* video: trust container FPS early on if possibleGravatar wm42018-05-25
| | | | | If the container FPS is correct, this can help getting ideal mix factors for vo_gpu interpolation mode. Otherwise, it doesn't matter.
* demux, player: fix playback of sparse video streams (w/ still images)Gravatar Aman Gupta2018-05-24
| | | | | | | | | | | | | | | Fixes several issues playing back mpegts with video streams marked as having "still images". For example, see this video which has frames only every 6s: https://s3.amazonaws.com/tmm1/music-choice.ts Changes include: - start playback right away, without waiting for first video frame - do not consider the sparse video stream in demuxer underrun detection - do not require multiple video frames for the VO - use audio as the master stream for demuxer metadata events - use audio stream for playback time Signed-off-by: Aman Gupta <aman@tmm1.net>
* encode: get rid of the output packet queueGravatar wm42018-05-03
| | | | | | | | | | | | Until recently, ao_lavc and vo_lavc started encoding whenever the core happened to send them data. Since audio and video are not initialized at the same time, and the muxer was not necessarily opened when the first encoder started to produce data, the resulting packets were put into a queue. As soon as the muxer was opened, the queue was flushed. Change this to make the core wait with sending data until all encoders are initialized. This has the advantage that we don't need to queue up the packets.
* video: actually wait for last frame being rendered on EOFGravatar wm42018-05-03
| | | | | | | | | | | | | | | | | | | The video timing code could just decide that EOF was reached before it was displayed. This is not really a problem for normal playback (if you use something like --keep-open it'd show the last frame anyway, otherwise it'd at best flash it on screen before destroying the window). But in encode mode, it really matters, and makes the difference between having one frame more or less in the output file. Fix this by waiting for the VO before starting the real EOF. vo_is_ready_for_frame() is normally used to determine when the VO frame queue has enough space to send a new frame. Since the VO frame queue is currently at most 1 frame, it being signaled means the remaining frame was consumed and thus sent to the VO driver. If it returns false, it will wake up the playloop as soon as the state changes. I also considered using vo_still_displaying(), but it's not reliable, because it checks the realtime of the frame end display time.
* player: don't wait for last video frame in encode modeGravatar wm42018-04-29
| | | | | This code makes the player wait using real time, which makes sense for normal playback, but not encode mode.
* encode: rewrite half of itGravatar wm42018-04-29
| | | | | | | | | | | | | The main change is that we wait with opening the muxer ("writing headers") until we have data from all streams. This fixes race conditions at init due to broken assumptions in the old code. This also changes a lot of other stuff. I found and fixed a few API violations (often things for which better mechanisms were invented, and the old ones are not valid anymore). I try to get away from the public mutex and shared fields in encode_lavc_context. For now it's still needed for some timestamp-related fields, but most are gone. It also removes some bad code duplication between audio and video paths.
* vo: add vo_reconfig2()Gravatar wm42018-04-29
| | | | | | 1. I want to get away from mp_image_params (maybe). 2. For encoding mode, it's convenient to get the nominal_fps, which is a mp_image field, and not in mp_image_params.
* vo: pass through framedrop flag differentlyGravatar wm42018-03-15
| | | | | | | | There is some sort-of awkwardness here, because option access needs to happen in a synchronized manner, and the framedrop flag is not in the VO option struct. Remove the mp_read_option_raw() call and the awkward change notification via VO_EVENT_WIN_STATE from command.c, and pass it through as new vo_frame flag.
* video: add option to reduce latency by 1 or 2 framesGravatar wm42018-03-03
| | | | | | | | | | | | | | | | | | | | The playback start logic explicitly waits until the first frame has been displayed. Usually this will introduce a wait of 1 vsync. For normal playback this doesn't matter, but with respect to low latency needs, this only leads to additional data getting queued up in the demuxer or network buffers. Another thing is that the timing logic decodes 1 frame ahead (= 1 frame extra latency) to determine the exact duration of a frame. To be fair, there doesn't really seem to be a hard reason why this is needed. With the current code, enabling the option does lead to A/V desync sometimes (if the demuxer FPS is too inaccurate), and also frame drops at playback start in some situations. But this all seems to be avoidable, if the timing logic were to be rewritten completely, which should probably happen in the future. Thus the new option comes with the warning that it can be removed any time. This is also why the option has "hack" in the name.
* video: don't read ahead a frame in --untimed modeGravatar wm42018-03-03
| | | | | The extra frame is used to compute the exact frame duration. But frame drop is disabvled with --untimed.
* client API: deprecate opengl-cb API and introduce a replacement APIGravatar wm42018-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | The purpose of the new API is to make it useable with other APIs than OpenGL, especially D3D11 and vulkan. In theory it's now possible to support other vo_gpu backends, as well as backends that don't use the vo_gpu code at all. This also aims to get rid of the dumb mpv_get_sub_api() function. The life cycle of the new mpv_render_context is a bit different from mpv_opengl_cb_context, and you explicitly create/destroy the new context, instead of calling init/uninit on an object returned by mpv_get_sub_api(). In other to make the render API generic, it's annoyingly EGL style, and requires you to pass in API-specific objects to generic functions. This is to avoid explicit objects like the internal ra API has, because that sounds more complicated and annoying for an API that's supposed to never change. The opengl_cb API will continue to exist for a bit longer, but internally there are already a few tradeoffs, like reduced thread-safety. Mostly untested. Seems to work fine with mpc-qt.
* video: do not buffer extra frames with VO_CAP_NORETAIN outputsGravatar Aman Gupta2018-02-17
| | | | | | | | | | | | | | This fixes playback stalls on some mediacodec hardware decoders, which expect that frame buffers will be rendered and returned back to the decoder as soon as possible. Specifically, the issue was observed on an NVidia SHIELD Android TV, only when playing an H264 sample which switched between interlaced and non-interlaced frames. On an interlacing change, the decoder expects all outstanding frames would be returned to it before it would emit any new frames. Since a single extra frame always remained buffered by mpv, playback would stall. After this commit, no extra frames are buffered by mpv when using vo_mediacodec_embed.
* video: fix passing down FPS to vf_vapoursynthGravatar wm42018-02-03
| | | | | | | To make this less of a mess, remove one of the redundant container_fps fields. Part of #5470.
* audio: move to decoder wrapperGravatar wm42018-01-30
| | | | | | | | | | | | | | | | Use the decoder wrapper that was introduced for video. This removes all code duplication the old audio decoder wrapper had with the video code. (The audio wrapper was copy pasted from the video one over a decade ago, and has been kept in sync ever since by the power of copy&paste. Since the original copy&paste was possibly done by someone who did not answer to the LGPL relicensing, this should also remove all doubts about whether any of this code is left, since we now completely remove any code that could possibly have been based on it.) There is some complication with spdif handling, and a minor behavior change (it will restrict the list of codecs to spdif if spdif is to be used), but there should not be any difference in practice.
* video: make decoder wrapper a filterGravatar wm42018-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | Move dec_video.c to filters/f_decoder_wrapper.c. It essentially becomes a source filter. vd.h mostly disappears, because mp_filter takes care of the dataflow, but its remains are in struct mp_decoder_fns. One goal is to simplify dataflow by letting the filter framework handle it (or more accurately, using its conventions). One result is that the decode calls disappear from video.c, because we simply connect the decoder wrapper and the filter chain with mp_pin_connect(). Another goal is to eventually remove the code duplication between the audio and video paths for this. This commit prepares for this by trying to make f_decoder_wrapper.c extensible, so it can be used for audio as well later. Decoder framedropping changes a bit. It doesn't seem to be worse than before, and it's an obscure feature, so I'm content with its new state. Some special code that was apparently meant to avoid dropping too many frames in a row is removed, though. I'm not sure how the source code tree should be organized. For one, video/decode/vd_lavc.c is the only file in its directory, which is a bit annoying.
* player: replace old lavfi wrapper with new filter codeGravatar wm42018-01-30
| | | | | lavfi.c is not necessary anymore, because f_lavfi.c (which was actually converted from it) can be used now.
* video: rewrite filtering glue codeGravatar wm42018-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the old vf.c code. Replace it with a generic filtering framework, which can potentially handle more than just --vf. At least reimplementing --af with this code is planned. This changes some --vf semantics (including runtime behavior and the "vf" command). The most important ones are listed in interface-changes. vf_convert.c is renamed to f_swscale.c. It is now an internal filter that can not be inserted by the user manually. f_lavfi.c is a refactor of player/lavfi.c. The latter will be removed once --lavfi-complex is reimplemented on top of f_lavfi.c. (which is conceptually easy, but a big mess due to the data flow changes). The existing filters are all changed heavily. The data flow of the new filter framework is different. Especially EOF handling changes - EOF is now a "frame" rather than a state, and must be passed through exactly once. Another major thing is that all filters must support dynamic format changes. The filter reconfig() function goes away. (This sounds complex, but since all filters need to handle EOF draining anyway, they can use the same code, and it removes the mess with reconfig() having to predict the output format, which completely breaks with libavfilter anyway.) In addition, there is no automatic format negotiation or conversion. libavfilter's primitive and insufficient API simply doesn't allow us to do this in a reasonable way. Instead, filters can use f_autoconvert as sub-filter, and tell it which formats they support. This filter will in turn add actual conversion filters, such as f_swscale, to perform necessary format changes. vf_vapoursynth.c uses the same basic principle of operation as before, but with worryingly different details in data flow. Still appears to work. The hardware deint filters (vf_vavpp.c, vf_d3d11vpp.c, vf_vdpaupp.c) are heavily changed. Fortunately, they all used refqueue.c, which is for sharing the data flow logic (especially for managing future/past surfaces and such). It turns out it can be used to factor out most of the data flow. Some of these filters accepted software input. Instead of having ad-hoc upload code in each filter, surface upload is now delegated to f_autoconvert, which can use f_hwupload to perform this. Exporting VO capabilities is still a big mess (mp_stream_info stuff). The D3D11 code drops the redundant image formats, and all code uses the hw_subfmt (sw_format in FFmpeg) instead. Although that too seems to be a big mess for now. f_async_queue is unused.
* msg: reinterpret a bunch of message levelsGravatar Niklas Haas2017-12-15
| | | | | | | | | | | | | | | | | | | | | | I've decided that MP_TRACE means “noisy spam per frame”, whereas MP_DBG just means “more verbose debugging messages than MSGL_V”. Basically, MSGL_DBG shouldn't create spam per frame like it currently does, and MSGL_V should make sense to the end-user and provide mostly additional informational output. MP_DBG is basically what I want to make the new default for --log-file, so the cut-off point for MP_DBG is if we probably want to know if for debugging purposes but the user most likely doesn't care about on the terminal. Also, the debug callbacks for libass and ffmpeg got bumped in their verbosity levels slightly, because being external components they're a bit less relevant to mpv debugging, and a bit too over-eager in what they consider to be relevant information. I exclusively used the "try it on my machine and remove messages from MSGL_* until it does what I want it to" approach of refactoring, so YMMV.
* video: add a shitty hack to avoid missing subtitles with vf_subGravatar wm42017-12-08
| | | | | | | | | | | | | | | | update_subtitles() makes sure all subtitle packets at/before the given PTS have been read and processed. Normally, this function is only called before sending a frame to the VO. This is too late for vf_sub, which expects the subtitles to be updated before feeding a frame to the filters. Apparently this was specifically a problem for the first frame. Subsequent frames might have been ok due to general prefetching. (This will fail anyway, should a filter dare to add an offset to the timestamps of the filered frames before they pass to vf_sub.) Fixes #5194.

* video: remove automatic stereo3d filter insertionGravatar wm42017-11-29
| | | | | | | | | | | | | The internal stereo3d filter was removed due to being GPL only, and due to being a mess that somehow used libavfilter's filter. Without this filter, it's hard to remove our internal stereo3d image attribute, so even using libavfilter's stereo3d filter would not work too well (unless someone fixes it and makes it able to use AVFrame metadata, which we then could mirror in mp_image). This was never well thought-through anyway, so just drop it. I think some "downsampling" support would still make sense, maybe that can be readded later.
* video: fix rotation and deinterlace auto filtersGravatar wm42017-11-29
| | | | | | | | Now using libavfilter filters directly. The rotation case is a bit lazy, because it uses the slow vf_rotate filter in all cases, instead of using special filters for 90° step rotations.
* video: fix typo in log messageGravatar Nicolas F2017-10-22

* video: fix poitential NULL derefGravatar wm42017-10-18
| | | | | Regression introduced by direct rendering code additions. Found by same static analyzer.
* audio: make libaf derived code optionalGravatar wm42017-09-21
| | | | | | | | | | | | | | | This code could not be relicensed. The intention was to write new filter code (which could handle both audio and video), but that's a bit of work. Write some code that can do audio conversion (resampling, downmixing, etc.) without the old audio filter chain code in order to speed up the LGPL relicensing. If you build with --disable-libaf, nothing in audio/filter/* is compiled in. It breaks a few features, such as --volume, --af, pitch correction on speed changes, replaygain. Most likely this adds some bugs, even if --disable-libaf is not used. (How the fuck does EOF notification work again anyway?)
* video: change --deinterlace behaviorGravatar wm42017-08-22
| | | | | | | | | | | | This removes all GPL only code from it, and that's the whole purpose. Also happens to be much simpler. The "deinterlace" option still sort of exists, but only as runtime changeable option. The main change in behavior is that the property will not report back the actual deint state. Or in other words, if inserting or initializing the filter fails, the deinterlace property will still return "yes". This is in line with most recent behavior changes to properties and options.
* video: redo video equalizer option handlingGravatar wm42017-08-22
| | | | | | | | | | | | | | | | | | | | | | | I really wouldn't care much about this, but some parts of the core code are under HAVE_GPL, so there's some need to get rid of it. Simply turn the video equalizer from its current fine-grained handling with vf/vo fallbacks into global options. This makes updating them much simpler. This removes any possibility of applying video equalizers in filters, which affects vf_scale, and the previously removed vf_eq. Not a big loss, since the preferred VOs have this builtin. Remove video equalizer handling from vo_direct3d, vo_sdl, vo_vaapi, and vo_xv. I'm not going to waste my time on these legacy VOs. vo.eq_opts_cache exists _only_ to send a VOCTRL_SET_EQUALIZER, which exists _only_ to trigger a redraw. This seems silly, but for now I feel like this is less of a pain. The rest of the equalizer using code is self-updating. See commit 96b906a51d5 for how some video equalizer code was GPL only. Some command line option names and ranges can probably be traced back to a GPL only committer, but we don't consider these copyrightable.
* audio: introduce a new type to hold audio framesGravatar wm42017-08-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is pretty pointless, but I believe it allows us to claim that the new code is not affected by the copyright of the old code. This is needed, because the original mp_audio struct was written by someone who has disagreed with LGPL relicensing (it was called af_data at the time, and was defined in af.h). The "GPL'ed" struct contents that surive are pretty trivial: just the data pointer, and some metadata like the format, samplerate, etc. - but at least in this case, any new code would be extremely similar anyway, and I'm not really sure whether it's OK to claim different copyright. So what we do is we just use AVFrame (which of course is LGPL with 100% certainty), and add some accessors around it to adapt it to mpv conventions. Also, this gets rid of some annoying conventions of mp_audio, like the struct fields that require using an accessor to write to them anyway. For the most part, this change is only dumb replacements of mp_audio related functions and fields. One minor actual change is that you can't allocate the new type on the stack anymore. Some code still uses mp_audio. All audio filter code will be deleted, so it makes no sense to convert this code. (Audio filters which are LGPL and which we keep will have to be ported to a new filter infrastructure anyway.) player/audio.c uses it because it interacts with the old filter code. push.c has some complex use of mp_audio and mp_audio_buffer, but this and pull.c will most likely be rewritten to do something else.
* player: make refresh seeks slightly more robustGravatar wm42017-08-14
| | | | | | | | | | | | | | | | | | | | | | Refresh seeks are automatically issued when changing filters, which improves user experience if these filters change buffering or such. The refresh seek could actually overwrite a previously ongoing seek: set pause yes set time-pos 10 set vf "" Here, the video code issued a refresh seek to the previous video position, which could be different from the previously triggered (and still ongoing) seek, this overwriting the seek. Factor all refresh seek handling into a new function, and make it handle ongoing seeks correctly. Remove the weird new canonical_pts field, which actually had no use. Fixes #4757.
* player: do not destroy VO immediately if there is no video trackGravatar wm42017-08-14
| | | | | | | | | | | Commit f1d161d55f45 accidentally added the handle_force_window() call if no track is selected. This was OK, but breaks something like "mpv *", where some files are not playable (like subtitle files) - the unplayable files would remove and recreate the VO window, which is annoying. Just drop the call again.
* player: make --lavfi-complex changeable at runtimeGravatar wm42017-08-12
| | | | | | | | Tends to be somewhat glitchy if subtitles are enabled, and you enable and disable tracks. On error, this will disable --lavfi-complex, which will result in whatever behavior.
* player: fix --lavfi-complex freezeGravatar wm42017-08-11
| | | | | | | | | | | | | | | | | | | Commit 0e0b87b6f3297 fixed that dropped packets did not trigger further work correctly. But it also made trivial --lavfi-complex freeze. The reason is that the meaning if DATA_AGAIN was overloaded: the decoders meant that they should be called again, while lavfi.c meant that other outputs needed to be checked again. Rename the latter meaning to DATA_STARVE, which means that the current input will deliver no more data, until "other" work has been done (like reading other outputs, or feeding input). The decoders never return DATA_STARVE, because they don't get input from the player core (instead, they get it from the demuxer directly, which is why they still can return DATA_WAIT). Also document the DATA_* semantics in the enum. Fixes #4746.
* vo_opengl: add direct rendering supportGravatar wm42017-07-24
| | | | | | | | | | | | | | | | | | | | Can be enabled via --vd-lavc-dr=yes. See manpage additions for what it does. This reminds of the MPlayer -dr flag, but the implementation is completely different. It's the same basic concept: letting the decoder render into a GPU buffer to avoid a copy. Unlike MPlayer, this doesn't try to go through filters (libavfilter doesn't support this anyway). Unless a filter can work in-place, DR will be silently disabled. MPlayer had very complex semantics about buffer types and management (which apparently nobody ever understood) and weird restrictions that mostly limited it to mpeg2 style codecs. The mpv code does not do any of this, and just lets the decoder allocate an arbitrary number of untyped images. (No MPlayer code was used.) Parts of the code based on work by atomnuker (starting point for the generic code) and haasn (some GL definitions, some basic PBO code, and correct fencing).
* player: change license of most core files to LGPLGravatar wm42017-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These files have all in common that they were fully or mostly taken from mplayer.c. (mplayer.c was a huge file that contains almost all of the playback core, until it was split into multiple parts.) This was probably the hardest part to relicense, because so much code was moved around all the time. player/audio.c still does not compile. We'll have to redo audio filtering. Once that is done, we can probably actually provide an actual LGPL configure switch. Here is a relatively detailed list of potential issues: 8d190244: author did not reply, parts were made GPL-only in a previous commit. 7882ea9b: author could not be reached, but the code is gone. wscript still has --datadir switch, but I don't think this is relevant to copyright. f197efd5: unclear origin, but I consider the code gone anyway (replaced with generic OSD mechanisms). 8337d9c2: author did not reply, but only the option still exists (under a different name), other code was removed. d8fd7131: did not reply. Disabled in a previous commit. 05258251: same author as above. Both fields actually seem to have vanished (even when tracking renames), so no action taken. d459e644, 268b2c1a: author did not reply, but we reuse only the options (with different names and slightly or fully different semantics, and completely different implementations), so I don't think this is relevant for copyright. 09e742fe, 17c39c4e: same as above. e8a173de, bff4b3ee: author could not be reached. The commands were reworked to properties, and the code outside of the TV code were moved back to the TV code. So I don't think copyright applies to the current command.c parts (mp_property_tv_color, mp_property_tv_freq, mp_property_tv_scan). The TV parts remain GPL. 0810e427: could not be reached. Disabled in a previous commit. 43744a2d: unknown author, but this was replaced by dynamic alloc (if the change is even copyrightable). 116ca0c7: unknown author; reasoning see input.c relicensing commit. e7e4d1d8: these semantics still exist, but as generic code, and this code was fully removed. f1175cd9: the author of the cited patch is unknown, and upon inspection it turns out that I was only using the idea to pause the player on EOF, so I claim it's not copyright relevant. 25affdcc: author could not be reached (yet) - but it's only a function rename, not copyrightable. 5728504c was committed by Arpi (who agreed), but hints that it might be by a different author. In fact it seems to be mostly this patch: http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2001-November/002041.html The author did not respond, but it all seems to have been removed later. It's a terrible mess though. Arpi reverted the A-V sync code at first, but left the RTC code for a while. The following commits remove these changes 100%: 14b35442, 7181a091, 31482783, 614f8475, df58e822. cehoyos did explicitly not agree to LGPL, but was involved in the following changes: c99d8fc8: applied a patch and didn't modify it, the original author agreed. 40ac0d31: author could not be reached, but all code is gone anyway. The "af" command has a similar function, but works completely different and actually reuses a mechanism older than this patch. 54350436: applied a patch, but didn't modify it, except for adding a German translation, which was removed later. a2dda036: same situation as above 240b743e: this was made GPL-only in a previous commit 7b25afd7: same as above (for now) kirijua could not be reached, but was a regular patch contributor: c2c997fd: video equalizer code move; probably not copyrightable. Is GPL due to Nick anyway. be54f481: technically, this became the audio track property later. But all what is left is the fact that you pass a track ID to it, so consider the original coypright non-relevant. 2f376d1b: this was rewritten in b7052b43, but for now we can afford to be careful, so this was marked as GPL only in a previous commit. 43844d09: remaining parts in main.c were reverted in a previous commit. anders has mostly disagreed with the LGPL relicensing. Does not want libaf to become LGPL, but made some concessions. In particular, he granted us permission to relicense 4943e9c52c and 242aa6ebd4. We also consider some of his changes remaining in mpv not relevant for copyright (such as 735de602 - we won't remove the this option completely). We will completely remove his other contributions, including the entire audio filter chain. For now, this stuff is marked as GPL only. The remaining question is how much code in player/audio.c (based on the former mplayer.c and dec_audio.c) is under his copyright. I made claims about this in a previous commit. Nick(ols) Kurshev, svn username "nick" and "nickols_k", could not be reached. He had a lot of changes in early MPlayer. It seems all of that was removed, at least in mpv. His main work, like VIDIX or libswscale work, does not exist in mpv anymore, but the changes to mplayer.c and other core parts still deserve attention: a4119f6b, fb927549, ad3529b8, e11b23dc, 5f2178be, 93c371d5: removed in b43d67e0, d1628d12, 24ed01fe, df58e822. 0a83c6ec, 104c125e, 4e067f62, aec5dcc8, b587a3d6, f3de6e6b: DR, VAA, and "tune" stuff was fully removed later on or replaced with other mechanisms. 340183b0: screenshots were redone later (the VOCTRL was even removed, with an independent implementation using the same VOCTRL a few years later), so not relevant anymore. Basically only the 's' shortcut remains (but not its implementation). 92c5c274, bffd4007, 555c6766: for now marked as GPL only in a previous commit. Might contain some trace amounts of "michael"'s copyright, who agreed to LGPL only once the core is relicensed. This will still be respected, but I don't think it matters at this in this case. (Some code touched by him was merged into mplayer.c, and then disappeared after heavy refactoring.) I tried to be as careful and as complete as possible. It can't be excluded that amends to this will be made later. This does not make the player LGPL yet.
* player: disable video equalizer frontend code for WIP LGPL modeGravatar wm42017-06-23
| | | | | | | | | | Nick and kiriuja could not be reached, and created/changed this in 92c5c274, 6441a5ad, bffd4007, 555c6766, c2c997fd. The video equalizer stuff was redone fully later, but there are still parts that look too similar and basically use the same approach. I'm more comfortable with declaring it GPL only for now. I plan to redo them later in a way that will remove copyright.
* player: disable deinterlace property for WIP LGPL modeGravatar wm42017-06-23
| | | | | | cehoyos has not agreed to the LGPL relicensing. He added the deinterlace property in commit 7b25afd7. Make it GPL-only for now. The still working parts of the --deinterlace option are not affected by his copyright.
* vo.c, vo.h, vo_null.c: change license to LGPLGravatar wm42017-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most contributors have agreed. vo.c requires a "driver" entry for each video output - we assume that if someone who didn't agree to LGPL added a line, it's fine for vo.c to be LGPL anyway. If the affected video output is not disabled at compilation time, the resulting binary will be GPL anyway. One problem are the changes by Nick Kurshev (usually using "nick" as SVN username). He could not be reached. I believe all changes to his files are actually gone, but here is a detailed listing: fa1d5742bc: nick introduces a new VO API. It was removed in 64bedd9683. Some of this was replaced by VOCTRLs are introduced in 7c51652a1b, obviously replacing at least some functionality by his API. b587a3d642: nick adds a vo_tune_info_t struct. Removed in 64bedd9683 too. 9caad2c29a: nick adds some VOCTRLs, which were silently removed in 8cc5ba5ab8 (they became unused probably with the VIDIX removal). 340183b0e9: nick adds VO-based screenshots, which got removed in 2f4b840f62. Strangely the same name was introduced in 01cf896a2f again, but this is a coincidence and worked differently (also it was removed yet again in 2858232220). 104c125e6d: nick adds an option for "direct rendering". It was renamed in 6403904ae9 and fully removed in e48b21dd87. 5ddd8e92a1: nick adds code to check the VO driver preinit arg to every single VO driver. The argument itself and any possibly remaining code associated with it was removed in 1f5ffe7d30. f6878753fb: nick adds header inclusion guards. We assume this is not relevant for copyright. Some of nick's code was merely moved to other files, such as the equalizer stuff added in 555c676683 and moved in 4db72f6a80 and 12579136ff, and don't affect copyright of these files anymore. Other notes: fef7b17c34: a patch by someone who wasn't asked for relicensing added a symbol that was removed again in 1b09f4633. 4a8a46fafd: author probably didn't agree to LGPL, but the function signature was changed later on anyway, and nothing of this is left. 7b25afd742: the same author adds a symbol to what is vo.h today, which this relicensing commit removes, as it was unused. (It's not clear whether the mere symbol is copyrightable, but no need to take a risk.) 3a406e94d7, 9dd8f241ac: slave mode things by someone who couldn't be reached. This aspect of the old slave mode was completely removed. bbeb54d80a: patch by someone who was not asked, but the added code was completely removed again.
* player: unmess pause state handlingGravatar wm42017-04-14
| | | | | | | | | Merge the pause_player() and unpause_player() functions. Make sure the pause events are emitted properly. We can now set the internal pause state based on a predicate, instead of e.g. handle_pause_on_low_cache() making a mess to trigger the internal pause state as wanted. Preparation for some more changes.
* video: deprecate almost all video filtersGravatar wm42017-04-02
| | | | | | | | | | | | | The plan is to nuke the custom filter chain completely. It's not clear what will happen to the still needed builtin filters (mostly hardware deinterlacing and vf_vapoursynth). Most likely we'll replace them with different filter chain concept (whose main purpose will be providing builtin things and bridging to libavfilter). The undocumented "warn" options are there to disable deprecation warnings when the player inserts filter automatically. The same will be done to audio filters, at a later point.
* lavfi: support hwdec filters for --lavfi-complexGravatar wm42017-02-20
| | | | | | Not so important by itself, but important for when we replace the vf libavfilter wrapper with the common implementation. (Which will hopefully happen, but not too soon.)
* player: print hw format on "VO: " line tooGravatar wm42017-01-29
| | | | | | | Useful for distinguishing bit depth when hardware decoding. (To the degree it's useful to show it at all. This just brings the hardware decoding case on the same level of showing information as the software decode call.)
* video: support filtering hardware frames via libavfilterGravatar wm42017-01-16
| | | | | | | | | | | | | | | | | | | | | | | | Requires a bunch of hacks: - we access AVFilterLink.hw_frames_ctx. This is not a public API in FFmpeg and Libav. Newer FFmpeg provides an accessor (av_buffersink_get_hw_frames_ctx), but it's not available in Libav or the current FFmpeg release or Libav. We need this value after filter graph creation, so We have no choice but to access this. One alternative is making filter creation and format negotiation fully lazy (i.e. delay it and do it as filters are output), but this would be a huge change. So for now, we knowingly violate FFmpeg's and Libav's ABI and API constraints because they don't provide anything better. On newer FFmpeg, we use the (quite ugly) accessor, though. - mp_image_params doesn't (and can't) have a field for the frames context AVBufferRef. So we pass it via vf_set_proto_frame(), and even more hacks. - if a filter needs a hw context, but we haven't created one yet (because normally we create them lazily), it will fail at init. - we allow any hw format now, although this could go horrible wrong. Why all this effort? We could move hw deinterlacing filters etc. to FFmpeg, which is a very worthy goal.
* player: change aspects of cover art handlingGravatar wm42017-01-10
| | | | | | | | | | | | | | | | | | | | | | | | Cover art handling is a disgusting hack that causes a mess in all components. And this will stay this way. This is the Xth time I've changed cover art handling, and that will probably also continue. But change the code such that cover art is injected into the demux packet stream, instead of having an explicit special case it in the decoder glue code. (This is somewhat more similar to the cover art hack in libavformat.) To avoid that the over art picture is decoded again on each seek, we need some additional "caching" in player/video.c. Decoding it after each seek would work as well, but since cover art pictures can be pretty huge, it's probably ok to invest some lines of code into caching it. One weird thing is that the cover art packet will remain queued after seeks, but that is probably not an issue. In exchange, we can drop the dec_video.c code, which is pretty convenient for one of the following commits. This code duplicates a bunch of lower-level decode calls and does icky messing with this weird state stuff, so I'm glad it goes away.
* video: use demuxer-signaled duration for last video frameGravatar wm42016-12-21
| | | | | | | | | Helps with gif, probably does unwanted things with other formats. This doesn't handle --end quite correctly, but this could be added later. Fixes #3924.
* manpage: replace `-vo` with `--vo`Gravatar Douglas Christman2016-12-08

* player: make sure non-video subtitle rendering is reset if video resumesGravatar wm42016-11-18
| | | | | | | | | | | | | | | | | If video reaches EOF, subtitle timing will be switched to timing without video frames. This means it calls osd_set_force_video_pts() and overrides the PTS of whatever video frame is current (since the video frame's PTS has nothing to do with the current playback position anymore). This was not reset when seeking back into video. Subtitles wouldn't show up, or if there was a subtitle displayed, it would get stuck with it. In particular, this could happen even if EOF was only temporary (such as with --keep-open). Fix this by clearing the override PTS whenever a video frame is shown. Fixes #3770.
* player: show subtitles on VO if --force-window is usedGravatar wm42016-10-26
| | | | | | | | | | | | | | | | | | | | | If a VO is created, but no video is playing (i.e. --force-window is used), then until now no subtitles were shown. This is because VO subtitle display normally depends on video frame timing. If there are no video frames, there can be no subtitles. Change this and add some code to handle this situation specifically. Set a subtitle PTS manually and request VO redrawing manually, which gets the subtitles rendered somehow. This is kind of shaky. The subtitles are essentially sampled at arbitrary times (such as when new audio data is decoded and pushed to the AO, or on user interaction). To make a it slightly more consistent, force a completely arbitrary minimum FPS of 10. Other solutions (such as creating fake video) would be more intrusive or would require VO-level API changes. Fixes #3684.
* player: speed up audio/video re-sync when there is a huge delayGravatar Aman Gupta2016-10-21
| | | | | | | | when there is a huge delay between audio/video sync, it can take a really long time to converge back. this speeds up the resync time by increasing the max_change allowed per iteration. Signed-off-by: wm4 <wm4@nowhere>
* player: make --stop-screensaver runtime-changeableGravatar wm42016-10-02
| | | | | | | | | | Move the screensaver enable/disable determination to a central place, and call it if the stop-screensaver property is changed. Also, do not stop the screensaver when in idle mode (i.e. no file is loaded). Fixes #3615.
* video: trust demuxer framerate on invalid timestampsGravatar wm42016-09-26
| | | | | | | | | If the PTS goes backwards (whether it's a timestamp reset or some other problem) would just use 0 as frame duration. (At least until the logic for detecting divergence with the timestamps gets active.) Trust the demuxer framerate in these cases instead, if it's available. I think this improves behavior slightly with some broken files.
