* av_log: mark as almost LGPLGravatar wm42017-05-05
| | | | | All authors agreed. Some of the code originated from commit 3c49701490aecb by michael, thus the license change has to be delayed.
* msg.c/h: partially change license to LGPLGravatar wm42017-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | msg.c is "partial" due to "michael", whose work can be changed to LGPL only once the core is LGPL. It's explained in the Copyright file. I prefer to do the relicensing incrementally (due to the overwhelming workload). Changing the license before that happens would be legally questionable, but nothing can stop us from essentially marking it as "will be LGPL". All authors have agreed to LGPL, with the following exceptions: 9df11ee8bf: the author (probably) didn't agree, but the line that is added is later fully removed. 35e90f1556: was not asked, but all iconv code was 100% removed from the mp_msg mechanism (we alwas require UTF-8 now). 4e4f3f806e: the change by michael. 50a86fcc34: the identify variable was move, and completely removed the latest in commit 48bd03dd91232. 1f6c494641: did not agree, but due to a major mp_msg change the added line became unnecessary and was removed. da63498bf9: was not reachable, but the MPlayer GUI is gone from mpv anyway (also commit fc4d6e617d8d removed these specific additions a long time ago).
* common.h: change license to LGPLGravatar wm42017-04-21
| | | | | | | | | | | The only definitions from MPlayer code are the CONTROL_* defines (added in 7a2eec4b as part of libao2 - not part of libao), and MP_NOPTS_VALUE, which was added in e6338c58. The latter is by "michael", who has agreed under the condition that the core is LGPL, which has not happened yet, but considering the macro definition used to be different, has the same value and similar name to libavformat's AV_NOPTS_VALUE (which existed first, and as LGPL), and that this almost certainly not copyrightable, I'm assuming that this is fine.
* video: support positional arguments for automatic lavfi option bridgeGravatar wm42017-04-03
| | | | | | Now e.g. --vf=pad=1000:1000 works. All in all pretty ugly and hacky. Just look away.
* encode_lavc: fix build failure after libavcodec major bumpGravatar wm42017-03-23

* options: add M_OPT_FILE to some more file optionsGravatar Philip Sequeira2017-03-06
| | | | (Helps shell completion.)
* Use AV_INPUT_BUFFER_PADDING_SIZE instead of deprecated oneGravatar wang-bin2017-02-08
| | | | Signed-off-by: wm4 <wm4@nowhere>
* player: add experimental stream recording featureGravatar wm42017-02-07
| | | | | This is basically a WIP, but it can't remain in a branch forever. A warning is print when using it as it's still a bit "shaky".
* build: explicitly check for FFmpeg vs. Libav, and their exact versionsGravatar wm42017-01-27
| | | | | | | | | | | | | | | | | | In a first pass, we check whether libavcodec is present. Then we try to compile a snippet and check for FFmpeg vs. Libav. (This could probably also be done by somehow checking the pkgconfig version. But pkg-config can't deal with that idiotic FFmpeg idea that a micro version number >= 100 identifies FFmpeg vs. Libav.) After that we check the project-specific version numbers. This means it can no longer happen that we accidentally allow older, unsupported versions of FFmpeg, just because the Libav version numbers are somehow this way. Also drop the resampler checks. We hardcode which resampler to each with each project. A user can no longer force use of libavresample with FFmpeg.
* ad_lavc, vd_lavc: preserve codec_id/codec_type when setting paramsGravatar wm42017-01-25
| | | | | | | | | | avcodec_parameters_to_context() overwrites codec_type and codec_id. But we already set these by passing the selected AVCodec to avcodec_alloc_context3(). It's entirely possible that at least codec_id is different when forcing codecs with --ad/--vd. It's probably better not to cause confusion by overwriting them. It might even trigger undefined behavior in libavcodec (how it behaves or whether codec_id is supposed to be strictly set is unknown, though).
* ad_lavc, vd_lavc: move mpv->lavc decoder parameter setup to common codeGravatar wm42017-01-25
| | | | | | | | This can be useful in other contexts. Note that we end up setting AVCodecContext.width/height instead of coded_width/coded_height now. AVCodecParameters can't set coded_width, but this is probably more correct anyway.
* av_common: remove old/unused timestamp passthrough codeGravatar wm42017-01-24
| | | | | | | | | | | | | | | | | | This attempted to pass through double float timestamps in a bit exact way by reinterpret casting them to int64_t. This usually worked, because libavcodec (in decoding mode) is mostly not allowed to interpret timestamps. libavcodec doesn't even know the unit of the timestamps, unless the API user sets a timebase. We've stopped doing this, and always set a timebase. Only ad_spdif.c still used this (indirectly through mp_set_av_packet()), but doesn't actually need timestamps on the packet. In fact, it's already explicitly setting the packet timestamp fields to 0 before passing it to FFmpeg API. This code is unused, and the passthrough method wasn't terribly elegant to begin with. Drop this code. Arbitrarily use AV_TIME_BASE_Q as fallback in situations the passthrough was used.
* av_common: drop unused functionGravatar wm42017-01-24
| | | | Unused since the AVCodecParameters change.
* options: drop deprecated --vd/--ad codecs selection featuresGravatar wm42017-01-19
| | | | | Only simple selection works now. Using "-" to terminate codec selection remains in the code (might get undeprecated).
* Prefix libavcodec CODEC_FLAG_ constants with AV_Gravatar wm42016-12-29
| | | | The unprefixed versions are silently deprecated.
* options: deprecate some other complex --ad/--vd featuresGravatar wm42016-12-23
| | | | | | | Who even needs those? Once these deprecations are gone, --ad/--vd are simple lists without any kind of complex matching.
* options: deprecate codec family selection in --vd/--adGravatar wm42016-12-23
| | | | | Useless now, so get rid of it. Also affects some user-visible display things (like reported codec in use).
* audio: change how spdif codecs are selectedGravatar wm42016-12-23
| | | | | | | | | | | | | | Remove ad_spdif from the normal codec list, and select it explicitly. One goal was to decouple this from the normal codec selection, so they're less entangled and the decoder selection code can be simplified in the far future. This means spdif codec selection is now done explicitly via select_spdif_codec(). We can also remove the weird requirements on "dts" and "dts-hd" for the --audio-spdif option, and it can just do the right thing. Now both video and audio codecs consist of a single codec family each, vd_lavc and ad_lavc.
* Remove compatibility thingsGravatar wm42016-12-07
| | | | | | Possible with bumped FFmpeg/Libav. These are just the simple cases.
* av_common: always make sure to return a valid timebaseGravatar wm42016-11-10
| | | | | | | | | | | | | | | av_reduce(&num, &den, 1, 14112000, 1000000) can return num=0, den=1. This means a 1/14112000 timebase (as used by the mp3 demuxer) would become invalid. The intention of mp_get_codec_timebase() is to always return a valid timebase. av_reduce() probably does the logically correct thing - so add a fallback to the safe default timebase. Also, increase the av_reduce() parameter to INT_MAX. Let's just pray this doesn't cause any actual problems. libavformat does the same, but might be in a different position due to using av_rescale() etc., while we convert between fractional timestamps and floats.
* demux_lavf: "support" mov edit lists and log errors if usedGravatar wm42016-10-18
| | | | | | | | | | | | | | | | | | | | | | | FFmpeg recently got "support" for mov edit lists. This is a terrible hack that will fail completely at least with some decoders (in particular wrappers for hardware decoding might be affected). As such it makes no point to pretend they are supported, even if we assume that the "intended" functionality works, that there are no implementation bugs (good luck with all that messy code added to the already huge mov demuxer), and that it covers enough of the mov edit list feature to be of value. So log an error if the FFmpeg code for mov edit lists appears to be active - AV_PKT_FLAG_DISCARD is used only for "clipping" edit list segments on non-key frame boundaries. In the first place, FFmpeg committed this only because Google wanted it in, and patch review did not even pick up obvious issues. (Just look how there was no lavc version bump when AV_PKT_FLAG_DISCARD was added.) We still pass the new packet flag to the decoders (av_common.c change), which means we "support" FFmpeg's edit list code now. (Until it breaks due to FFmpeg not caring about all the details.)
* ad_lavc, vd_lavc: fix a recent libavcodec deprecation warningGravatar wm42016-10-17
| | | | | | | | | | | | | | Both AVFrame.pts and AVFrame.pkt_pts have existed for a long time. Until now, decoders always returned the pts via the pkt_pts field, while the pts field was used for encoding and libavfilter only. Recently, pkt_pts was deprecated, and pts was switched to always carry the pts. This means we have to be careful not to accidentally use the wrong field, depending on the libavcodec version. We have to explicitly check the version numbers. Of course the version numbers are completely idiotic, because idiotically the pkg-config and library names are the same for FFmpeg and Libav, so we have to deal with this explicitly as well.
* msg: flush after every message for --log-fileGravatar wm42016-09-30
| | | | | | We'd like to get log messages on the output as soon as possible in the output. I also feel like using fflush() is nicer than using setvbuf(). Who knows how the latter behaves on win32.
* msg: make --log-file and --dump-stats accept config path expansionGravatar wm42016-09-28
| | | | | | | | | Seems like a valid use-case. Not sure if I like it calling back into the config code. Care has to be taken for not letting the config path resolving code dead-lock (which is why locking details in the msg.c code are changed). Fixes #3591.
* client API: more or less deprecate mpv_set_option()Gravatar wm42016-09-21
| | | | | | | | | | | | | | | | | | | | | | With the merging of options and properties, the mpv_set_option() function is close to being useless, and mpv_set_property() can be used for everything instead. There are certain conflicts remaining, which are explained in depth in the docs. For now, none of this should affect existing code using the client API. Make mpv_set_property() redirect to mpv_set_option() before initialization. Remove some options marked as M_OPT_FIXED. The "pause" and "speed" options cannot be written anymore without the playloop being notified by it, so the M_OPT_FIXED does nothing. For "vo-mmcss-profile", the problem was lack of synchronization, which has been added. I'm not sure what the problem was with "frames" - I think it was only marked as M_OPT_FIXED because changing it during playback will have no effect. Except for pause/speed, these changes are needed to make them writable as properties after mpv_initialize(). Also replace all remaining uses of CONF_GLOBAL with M_OPT_FIXED.
* player: make --log-file and --dump-stats freely settable at runtimeGravatar wm42016-09-19
| | | | | Same deal as with the previous commit. We use the file paths to decide when we should attempt to reopen them.
* osdep: rename atomics.h to atomic.hGravatar wm42016-09-07
| | | | | The standard header is stdatomic.h, so the extra "s" freaks me out every time I look at it.
* common: use char array for version stringGravatar wm42016-09-06
| | | | | Use a char array instead of a pointer, which allows using the version variables in a constant context.
* m_config: introduce basic mechanism to synchronize global option updatesGravatar wm42016-09-02
| | | | | | | | | | | | | | | | | | The way option runtime changes are handled is pretty bad in the current codebase. There's a big option struct (MPOpts), which contains almost everything, and for which no synchronization mechanism exists. This was handled by either making some options read-only after initialization, duplicating the option struct, using sub-options (in the VO), and so on. Introduce a mechanism that creates a copy of the global options (or parts of it), and provides a well-defined way to update them in a thread-safe way. Most code can remain the same, just that all the component glue code has to explicitly make use of it first. There is still lots of room for improvement. For example, the update mechanism could be better.
* common: add assert.h includeGravatar wm42016-08-28
| | | | Because why not.
* video/audio: always provide "proper" timestamps to libavcodecGravatar wm42016-08-19
| | | | | | | | | | | | | | | | | | | Instead of passing through double float timestamps opaquely, pass real timestamps. Do so by always setting a valid timebase on the AVCodecContext for audio and video decoding. Specifically try not to round timestamps to a too coarse timebase, which could round off small adjustments to timestamps (such as for start time rebasing or demux_timeline). If the timebase is considered too coarse, make it finer. This gets rid of the need to do this specifically for some hardware decoding wrapper. The old method of passing through double timestamps was also a bit questionable. While libavcodec is not supposed to interpret timestamps at all if no timebase is provided, it was needlessly tricky. Also, it actually does compare them with AV_NOPTS_VALUE. This change will probably also reduce confusion in the future.
* av_common: improve rounding for float->int timestamp conversionsGravatar wm42016-08-19

* player: fatal error if linked and compiled FFmpeg versions mismatchGravatar wm42016-07-01
| | | | | | | | | We don't support this anymore. This tries to exit in a controlled way after command line options are applied in order to honor logging options and, in case of libmpv, not to kill the host. Not sure if it would be better to just vomit text to stderr and call abort().
* av_log: readd ffmpeg library runtime version mismatch warningGravatar wm42016-05-01
| | | | It just happens far too often.
* encode_lavc: Migrate to codecpar API.Gravatar Rudolf Polzer2016-04-11
|
* demux_lavf, ad_lavc, ad_spdif, vd_lavc: handle FFmpeg codecpar API changeGravatar wm42016-03-31
| | | | | | | | | AVFormatContext.codec is deprecated now, and you're supposed to use AVFormatContext.codecpar instead. Handle this for all of the normal playback code. Encoding mode isn't touched.
* playlist: improve shuffle algorithmGravatar Niklas Haas2016-03-20
| | | | | | | | | | | The old algorithm produced results which were not uniformly distributed, i.e. some particular shuffles were preferred over others. The new algorithm is an implementation of the Fisher-Yates shuffle which is guaranteed to shuffle uniformly given a sufficiently uniform rand() and ignoring potential floating-point errors.

* av_common: explicitly exclude _vdpau deccoders from enumerationGravatar wm42016-03-02
| | | | | | | | | | Completely pointless abominations that FFmpeg refuses to remove. They are ancient, long deprecated API which we can't use anymore. They confused users as well. Pretend that they don't exist. Due to the way --vd works, they can't even be forced anymore. The older hack which explicitly rejects these can be dropped as well.
* msg: introduce partial line buffers per mp_logGravatar wm42016-03-01
| | | | | | | | | | | | | | | | The goal is reducing log messups (which happen surprisingly often) by buffering partial lines in mp_log. This is still not 100% reliable, but better. The extrabuffers for MSGL_STATUS and MSGL_STATS are not needed anymore, because a separate mp_log instance can be used if problems really occur. Also, give up, and replace the snprintf acrobatics with bstr. mp_log.partial has a quite subtle problem wrt. talloc: talloc parents can not be used, because there's no lock around the internal talloc structures associated with mp_log. Thus it has to be freed manually, even if this happens through a talloc destructor.
* msg: minor simplificationGravatar wm42016-03-01
| | | | | Instead of playing ugly tricks with the buffer to append a \r or \n to the text buffer, extend print_terminal_line() to print a second string.
* av_log: avoid partial linesGravatar wm42016-03-01
| | | | | | | | | | | | | We want to add a prefix to the ffmpeg log message, so we called mp_msg multiple times until now. But logging such partial lines is a race condition, because there's only one internal mp_msg buffer, and no external mp_msg locks. Avoid this by building the message on a stack buffer. I might make a mp_log-local partial line buffer, but even then av_log() can be called from multiple threads, while targetting the same mp_log. (Really, ffmpeg's log API needs to be fixed.)
* msg: use dynamic buffer for message formattingGravatar wm42016-03-01
| | | | | | | | | | | | | | | | | Until now, a rather large stack buffer was used for this, and also a static buffer in mp_log_root. The latter was added to buffer partial lines, and the stack buffer was used only for MSGL_STATUS and MSGL_STATS (I guess because these are the most likely/severe to clash with partial line buffering). Make the buffer in mp_log_root dynamically sized, so we don't get cut off log lines if the text is excessively large. (The OpenGL extension list dumped by vo_opengl is such an example.) Since we still have to support partial line buffering (FFmpeg's log callbacks leave no other choice), keep the stack buffer. But make it smaller; there's no way all ~6KB are going to be needed in any situation.
* command: add encoder-list propertyGravatar wm42016-03-01
| | | | | Also change decoder-list (for the sake of sharing the underlying code for both properties).
* Initial Android supportGravatar Jan Ekström2016-02-10
| | | | | * Adds an 'android' feature, which is automatically detected. * Android has a broken strnlen, so a wrapper is added from FreeBSD.
* common/common.c: handle utf16 in mp_parse_escapeGravatar kwkam2016-02-06
| | | | Signed-off-by: wm4 <wm4@nowhere>
* build: make libavfilter mandatoryGravatar wm42016-02-05
| | | | | | The complex filter support that will be added makes much more complex use of libavfilter, and I'm not going to bother with adding hacks to keep libavfilter optional.
* audio/video: merge decoder return valuesGravatar wm42016-02-01
| | | | | | Will be helpful for the coming filter support. I planned on merging audio/video decoding, but this will have to wait a bit longer, so only remove the duplicate status codes.
* Relicense some non-MPlayer source files to LGPL 2.1 or laterGravatar wm42016-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This covers source files which were added in mplayer2 and mpv times only, and where all code is covered by LGPL relicensing agreements. There are probably more files to which this applies, but I'm being conservative here. A file named ao_sdl.c exists in MPlayer too, but the mpv one is a complete rewrite, and was added some time after the original ao_sdl.c was removed. The same applies to vo_sdl.c, for which the SDL2 API is radically different in addition (MPlayer supports SDL 1.2 only). common.c contains only code written by me. But common.h is a strange case: although it originally was named mp_common.h and exists in MPlayer too, by now it contains only definitions written by uau and me. The exceptions are the CONTROL_ defines - thus not changing the license of common.h yet. codec_tags.c contained once large tables generated from MPlayer's codecs.conf, but all of these tables were removed. From demux_playlist.c I'm removing a code fragment from someone who was not asked; this probably could be done later (see commit 15dccc37). misc.c is a bit complicated to reason about (it was split off mplayer.c and thus contains random functions out of this file), but actually all functions have been added post-MPlayer. Except get_relative_time(), which was written by uau, but looks similar to 3 different versions of something similar in each of the Unix/win32/OSX timer source files. I'm not sure what that means in regards to copyright, so I've just moved it into another still-GPL source file for now. screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but they're all gone.
* global: add client API pointer to library handleGravatar wm42016-01-15
| | | | | | | Makes the next commit simpler. It's probably a bad idea to add more fields to the global state, but on the other hand the client API state is pretty much per-instance anyway. It also will help with things like the proposed libmpv custom stream API.
* mpv_talloc.h: rename from talloc.hGravatar Dmitrij D. Czarkoff2016-01-11
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
