* manpage: Correct show-text duration default valueGravatar jaseg2018-08-05
| | | duration is parsed as an integer, and the default value is used if ```-1``` is passed. Passing ```-``` as described here causes a parameter value error.
* command: change cycle-value command behaviorGravatar wm42018-04-29
| | | | | | | | | | | | | | | | | | | | Instead of using an internal counter to keep track of the value that was set last, attempt to find the current value of the property/option in the value list, and then set the next value in the list. There are some potential problems. If a property refuses to accept a specific value, the cycle-values command will fail, and start from the same position again. It can't know that it's supposed to skip the next value. The same can happen to properties which behave "strangely", such as the "aspect" property, which will return the current aspect if you write "-1" to it. As a consequence, cycle-values can appear to get "stuck". I still think the new behavior is what users expect more, and which is generally more useful. We won't restore the ability to get the old behavior, unless we decide to revert this commit entirely. Fixes #5772, and hopefully other complaints.
* scripting: change when/how player waits for scripts being loadedGravatar wm42018-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fundamentally, scripts are loaded asynchronously, but as a feature, there was code to wait until a script is loaded (for a certain arbitrary definition of "loaded"). This was done in scripting.c with the wait_loaded() function. This called mp_idle(), and since there are commands to load/unload scripts, it meant the player core loop could be entered recursively. I think this is a major complication and has some problems. For example, if you had a script that does 'os.execute("sleep inf")', then every time you ran a command to load an instance of the script would add a new stack frame of mp_idle(). This would lead to some sort of reentrancy horror that is hard to debug. Also misc/dispatch.c contains a somewhat tricky mess to support such recursive invocations. There were also some bugs due to this and due to unforeseen interactions with other messes. This scripting stuff was the only thing making use of that reentrancy, and future commands that have "logical" waiting for something should be implemented differently. So get rid of it. Change the code to wait only in the player initialization phase: the only place where it really has to wait is before playback is started, because scripts might want to set options or hooks that interact with playback initialization. Unloading of builtin scripts (can happen with e.g. "set osc no") is left asynchronous; the unloading wasn't too robust anyway, and this change won't make a difference if someone is trying to break it intentionally. Note that this is not in mp_initialize(), because mpv_initialize() uses this by locking the core, which would have the same problem. In the future, commands which logically wait should use different mechanisms. Originally I thought the current approach (that is removed with this commit) should be used, but it's too much of a mess and can't even be used in some cases. Examples are: - "loadfile" should be made blocking (needs to run the normal player code and manually unblock the thread issuing the command) - "add-sub" should not freeze the player until the URL is opened (needs to run opening on a separate thread) Possibly the current scripting behavior could be restored once new mechanisms exist, and if it turns out that anyone needs it. With this commit there should be no further instances of recursive playloop invocations (other than the case in the following commit), since all mp_idle()/mp_wait_events() calls are done strictly from the main thread (and not commands/properties or libmpv client API that "lock" the main thread).
* client API: add a first class hook API, and deprecate old APIGravatar wm42018-03-26
| | | | | | | | | | | | | | | As it turns out, there are multiple libmpv users who saw a need to use the hook API. The API is kind of shitty and was never meant to be actually public (it was mostly a hack for the ytdl script). Introduce a proper API and deprecate the old one. The old one will probably continue to work for a few releases, but will be removed eventually. There are some slight changes to the old API, but if a user followed the manual properly, it won't break. Mostly untested. Appears to work with ytdl_hook.
* doc: fix formatting of video-frame-info propertiesGravatar Aman Gupta2018-03-11

* codecs: remove unused family fieldGravatar wm42018-02-01
| | | | | | | | | | MPlayer used this to distinguish multiple decoder wrappers (such as libavcodec vs. binary codec loader vs. builtin decoders). It lost meaning in mpv as non-libavcodec things were dropped. Now it doesn't serve any purpose anymore. Parsing was removed quite a while ago, and the recent filter change removed any use of the internal family field. Get rid of it.
* command: add a change-list commandGravatar wm42018-01-25
| | | | | | | | | | | | | Requested. See manpage additions. The main reason why this goes through the trouble to keep the action/operation parameter separate is so that we don't expose some option parser implementation details to the command (although that is a relatively weak reason), and also to make it more different from the "set" command, which can't support this type of option as it goes through the property layer. Fixes #5435.
* manpage: reword some vf command examplesGravatar wm42018-01-18

* player: remove internal `vo-resize` command againGravatar sfan52018-01-02
| | | | Its only usecase was automated in the previous commit.
* command: add demuxer-lavf-list propertyGravatar Ricardo Constantino2018-01-02
| | | | | | | | | Was only available with --demuxer-lavf-format=help and the demuxer needed to be used for it to actually print the list. This can be used in the future to check if 'dash' support was compiled with FFmpeg so ytdl_hook can use it instead. For now, dashdec is too rudimentary to be used right away.
* player: add on_load_fail hookGravatar Ricardo Constantino2018-01-02

* player: add internal `vo-resize` commandGravatar sfan52017-12-27
| | | | Intended to be used with the properties from previous commit.
* player: show demuxer cache buffered amount in bytes in the status lineGravatar wm42017-12-23
| | | | | | | | I don't want to add another field to display stream and demuxer cache separately, so just add them up. This strangely makes sense, since the forward buffered stream cache amount consists of data not read by the demuxer yet. (If the demuxer cache has buffered the full stream, the forward buffered stream cache amount is 0.)
* vo_gpu: make it possible to load multiple hwdec interop driversGravatar wm42017-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the VO<->decoder interface capable of supporting multiple hwdec APIs at once. The main gain is that this simplifies autoprobing a lot. Before this change, it could happen that the VO loaded the "wrong" hwdec API, and the decoder was stuck with the choice (breaking hw decoding). With the change applied, the VO simply loads all available APIs, so autoprobing trickery is left entirely to the decoder. In the past, we were quite careful about not accidentally loading the wrong interop drivers. This was in part to make sure autoprobing works, but also because libva had this obnoxious bug of dumping garbage to stderr when using the API. libva was fixed, so this is not a problem anymore. The --opengl-hwdec-interop option is changed in various ways (again...), and renamed to --gpu-hwdec-interop. It does not have much use anymore, other than debugging. It's notable that the order in the hwdec interop array ra_hwdec_drivers[] still matters if multiple drivers support the same image formats, so the option can explicitly force one, if that should ever be necessary, or more likely, for debugging. One example are the ra_hwdec_d3d11egl and ra_hwdec_d3d11eglrgb drivers, which both support d3d11 input. vo_gpu now always loads the interop lazily by default, but when it does, it loads them all. vo_opengl_cb now always loads them when the GL context handle is initialized. I don't expect that this causes any problems. It's now possible to do things like changing between vdpau and nvdec decoding at runtime. This is also preparation for cleaning up vd_lavc.c hwdec autoprobing. It's another reason why hwdec_devices_request_all() does not take a hwdec type anymore.
* demux: export demuxer cache sizes in bytesGravatar wm42017-11-10
| | | | | | Plus sort of document them, together with the already existing undocumented fields. (This is mostly for debugging, so use is discouraged.)
* demux: support multiple seekable cached rangesGravatar wm42017-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the demuxer cache was limited to a single range. Extend this to multiple range. Should be useful for slow network streams. This commit changes a lot in the internal demuxer cache logic, so there's a lot of room for bugs and regressions. The logic without demuxer cache is mostly untouched, but also involved with the code changes. Or in other words, this commit probably fucks up shit. There are two things which makes multiple cached ranges rather hard: 1. the need to resume the demuxer at the end of a cached range when seeking to it 2. joining two adjacent ranges when the lowe range "grows" into it (and resuming the demuxer at the end of the new joined range) "Resuming" the demuxer means that we perform a low level seek to the end of a cached range, and properly append new packets to it, without adding packets multiple times or creating holes due to missing packets. Since audio and video never line up exactly, there is no clean "cut" possible, at which you could resume the demuxer cleanly (for 1.) or which you could use to detect that two ranges are perfectly adjacent (for 2.). The way how the demuxer interleaves multiple streams is also unpredictable. Typically you will have to expect that it randomly allows one of the streams to be ahead by a bit, and so on. To deal with this, we have heuristics in place to detect when one packet equals or is "behind" a packet that was demuxed earlier. We reuse the refresh seek logic (used to "reread" packets into the demuxer cache when enabling a track), which checks for certain packet invariants. Currently, it observes whether either the raw packet position, or the packet DTS is strictly monotonically increasing. If none of them are true, we discard old ranges when creating a new one. This heavily depends on the file format and the demuxer behavior. For example, not all file formats have DTS, and the packet position can be unset due to libavformat not always setting it (e.g. when parsers are used). At the same time, we must deal with all the complicated state used to track prefetching and seek ranges. In some complicated corner cases, we just give up and discard other seek ranges, even if the previously mentioned packet invariants are fulfilled. To handle joining, we're being particularly dumb, and require a small overlap to be confident that two ranges join perfectly. (This could be done incrementally with as little overlap as 1 packet, but corner cases would eat us: each stream needs to be joined separately, and the cache pruning logic could remove overlapping packets for other streams again.) Another restriction is that switching the cached range will always trigger an asynchronous low level seek to resume demuxing at the new range. Some users might find this annoying. Dealing with interleaved subtitles is not fully handled yet. It will clamp the seekable range to where subtitle packets are.
* demux: improve and optimize cache pruning and seek range determinationGravatar wm42017-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | The main purpose of this commit is avoiding any hidden O(n^2) algorithms in the code for pruning the demuxer cache, and for determining the seekable boundaries of the cache. The old code could loop over the whole packet queue on every packet pruned in certain corner cases. There are two ways how to reach the goal: 1) commit a cardinal sin 2) do everything incrementally The cardinal sin is adding an extra field to demux_packet, which caches the determined seekable range for a keyframe range. demux_packet is a rather general data structure and thus shouldn't have any fields that are not inherent to its use, and are only needed as an implementation detail of code using it. But what are you gonna do, sue me? In the future, demux.c might have its own packet struct though. Then the other existing cardinal sin (the "next" field, from MPlayer times) could be removed as well. This commit also changes slightly how the seek end is determined. There is a note on the manpage in case anyone finds the new behavior confusing. It's somewhat cleaner and might be needed for supporting multiple ranges (although that's unclear).
* command: change demuxer-cache-state property to return multiple rangesGravatar wm42017-10-26
| | | | | | | | | | | | | | | | | | Even if the demuxer cache does not multiple ranges yet. This is to reduce the pain should caching of multiple ranges ever be implemented. Also change it from the sub properties stuff to return a mpv_node directly, which is less roundabout. Sub-property access won't work anymore, though. Remove the seekable-start/-end fields as well, as they're redundant with the ranges. All this would normally be considered an API change, but since it's been only a few days with no known users, change it immediately. This adds some node.c helpers as well, as the code would be too damn fugly otherwise.
* command: read the diff if you want to knowGravatar wm42017-10-21

* manpage: correct some comments about ordered chaptersGravatar wm42017-10-11
| | | | | Ordered chapters behavior changed at some point, and all of this was outdated.
* command: drop "audio-out-detected-device" propertyGravatar wm42017-10-09
| | | | | | Coreaudio stopped setting it a few releases ago (66a958bb4fa). There is not much of a user- or API-visible change, so remove it without deprecation.
* 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.
* manpage: video equalizer properties now behave differentlyGravatar wm42017-08-22
| | | | No more special behavior.
* manpage: remove removed "osd" commandGravatar wm42017-08-22
| | | | Someone pointed this out on github.
* vo_opengl: refactor vo performance subsystemGravatar Niklas Haas2017-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces `vo-performance` by `vo-passes`, bringing with it a number of changes and improvements: 1. mpv users can now introspect the vo_opengl passes, which is something that has been requested multiple times. 2. performance data is now measured per-pass, which helps both development and debugging. 3. since adding more passes is cheap, we can now report information for more passes (e.g. the blit pass, and the osd pass). Note: we also switch to nanosecond scale, to be able to measure these passes better. 4. `--user-shaders` authors can now describe their own passes, helping users both identify which user shaders are active at any given time as well as helping shader authors identify performance issues. 5. the timing data per pass is now exported as a full list of samples, so projects like Argon-/mpv-stats can immediately read out all of the samples and render a graph without having to manually poll this option constantly. Due to gl_timer's design being complicated (directly reading performance data would block, so we delay the actual read-back until the next _start command), it's vital not to conflate different passes that might be doing different things from one frame to another. To accomplish this, the actual timers are stored as part of the gl_shader_cache's sc_entry, which makes them unique for that exact shader. Starting and stopping the time measurement is easy to unify with the gl_sc architecture, because the existing API already relies on a "generate, render, reset" flow, so we can just put timer_start and timer_stop in sc_generate and sc_reset, respectively. The ugliest thing about this code is that due to the need to keep pass information relatively stable in between frames, we need to distinguish between "new" and "redrawn" frames, which bloats the code somewhat and also feels hacky and vo_opengl-specific. (But then again, this entire thing is vo_opengl-specific)
* vo_opengl: implement support for OOTFs and non-display referred contentGravatar Niklas Haas2017-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces (yet another..) mp_colorspace members, an enum `light` (for lack of a better name) which basically tells us whether we're dealing with scene-referred or display-referred light, but also a bit more metadata (in which way is the scene-referred light expected to be mapped to the display?). The addition of this parameter accomplishes two goals: 1. Allows us to actually support HLG more-or-less correctly[1] 2. Allows people playing back direct “camera” content (e.g. v-log or s-log2) to treat it as scene-referred instead of display-referred [1] Even better would be to use the display-referred OOTF instead of the idealized OOTF, but this would require either native HLG support in LittleCMS (unlikely) or more communication between lcms.c and video_shaders.c than I'm remotely comfortable with That being said, in principle we could switch our usage of the BT.1886 EOTF to the BT.709 OETF instead and treat BT.709 content as being scene-referred under application of the 709+1886 OOTF; which moves that particular conversion from the 3dlut to the shader code; but also allows a) users like UliZappe to turn it off and b) supporting the full HLG OOTF in the same framework. But I think I prefer things as they are right now.
* video: refactor HDR implementationGravatar Niklas Haas2017-06-18
| | | | | | | | | | | | | | | List of changes: 1. Kill nom_peak, since it's a pointless non-field that stores nothing of value and is _always_ derived from ref_white anyway. 2. Kill ref_white/--target-brightness, because the only case it really existed for (PQ) actually doesn't need to be this general: According to ITU-R BT.2100, PQ *always* assumes a reference monitor with a white point of 100 cd/m². 3. Improve documentation and comments surrounding this stuff. 4. Clean up some of the code in general. Move stuff where it belongs.
* command: add all options to property->option bridgeGravatar wm42017-06-15
| | | | | | | | | | | | | | | | Before this, options with co->data==NULL (i.e. no storage) were not added to the bridge (except alias options). There are a few options which might make sense to allow via the bridge ("profile" and "include"). So allow them. In command_init(), we merely remove the co->data check, the rest of the diff is due to switching the if/else branches for convenience. We also must explicitly error on M_PROPERTY_GET if co->data==NULL. All other cases check it in some way. Explicitly exclude options from the property bridge, which would be added due this, and the result would be pointless.
* manpage, client API: add some clarifications when commands use OSDGravatar wm42017-04-01
| | | | | The APIs that run commands in a more API-like manner disable OSD and string expansion by default.

* player: make screenshot commands honor the async flagGravatar wm42017-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | And also change input.conf to make all screenshots async. (Except the every-frame mode, which always uses synchronous mode and ignores the flag.) By default, the "screenshot" command is still asynchronous, because scripts etc. might depend on this behavior. This is only partially async. The code for determining the filename is still always run synchronously. Only encoding the screenshot and writing it to disk is asynchronous. We explicitly document the exact behavior as undefined, so it can be changed any time. Some of this is a bit messy, because I wanted to avoid duplicating the message display code between sync and async mode. In async mode, this is called from a worker thread, which is not safe because showing a message accesses the thread-unsafe OSD code. So the core has to be locked during this, which implies accessing the core and all that. So the code has weird locking calls, and we need to do core destruction in a more "controlled" manner (thus the outstanding_async field). (What I'd really want would be the OSD simply showing log messages instead.) This is pretty untested, so expect bugs. Fixes #4250.
* input: add "async" flagGravatar wm42017-04-01
| | | | | | | | | | | Obviously, this has no effect on commands which do not support this explicitly. A later commit will enable this for screenshots. Also add some wording on mpv_command_async(), which has nothing to do with this. Having a more elegant, unified behavior would be nice. But the API function was not created for this - it's merely for running commands _synchronously_ on the core, but without blocking the client API caller (if the API user consistently uses only async functions).
* command: add expand-text command to property-expand a stringGravatar Avi Halachmi (:avih)2017-03-26
|
* command: change and simplify filter toggle syntaxGravatar wm42017-03-26
| | | | | | | | | | | "@name:!" becomes simply "@name". This is actually slightly more complex to parse, but makes for a much simpler syntax and will be less weird to the user. Suggested by haasn. The old syntax is now rejected with an error. Also add some more explicit error checks, instead of e.g. allowing empty filter names and erroring only when it's not found.
* m_option: consistent af/vf filter entry "enabled" flag default valueGravatar wm42017-03-25
| | | | | | | It should default to true, but setting the filter list via mpv_node (relevant for client API and Lua scripting) left it to false. Also "document" the flag.
* command: add better runtime filter toggling methodGravatar wm42017-03-25
| | | | | | | | | | Basically, see the example in input.rst. This is better than the "old" vf-toggle method, because it doesn't require the user to duplicate the filter string in mpv.conf and input.conf. Some aspects of this changes are untested, so enjoy your alpha testing.
* command: add demux-start-time propertyGravatar Matthias Hunstock2017-03-25
| | | | Add a demux_start_time property, update docs.
* command: add a property to signal whether networking is usedGravatar wm42017-03-24
| | | | | | Requested. The property semantics are a bit muddy due to lack of effort. Anticipated use is different display of cache status, so it should not matter anyway.
* manpage: slightly improve screenshot-raw descriptionGravatar wm42017-03-18

* manpage: minor clarification to screenshot command argument handlingGravatar wm42017-03-15

* player: remove --stream-capture option/propertyGravatar wm42017-01-21
| | | | | | | | | | | | | | | This was excessively useless, and I want my time back that was needed to explain users why they don't want to use it. It captured the byte stream only, and even for types of streams it was designed for (like transport streams), it was rather questionable. As part of the removal, un-inline demux_run_on_thread() (which has only 1 call-site now), and sort of reimplement --stream-dump to write the data directly instead of using the removed capture code. (--stream-dump is also very useless, and I struggled coming up with an explanation for it in the manpage.)
* command: rename framedrop propertiesGravatar wm42017-01-20
| | | | | | | | | | "drop-frame-count" -> "decoder-frame-drop-count" "vo-drop-frame-count" -> "frame-drop-count" This gets rid of the backwards "drop-frame" part in the name. Maybe calling the new property "frame-drops" would be better, but there are already a bunch of similar properties that end in "-count".
* vo_opengl, vo_opengl_cb: better hwdec interop backend selectionGravatar wm42017-01-17
| | | | | | | | | | | Introduce the --opengl-hwdec-interop option, which replaces --hwdec-preload. The new option allows explicit selection of the interop backend. This is relatively complex, and I would have preferred not to add this, but it's probably useful to debug certain problems. In exchange, the "new" option documents that pretty much any but the simplest use of it will not be forward compatible.
* command: redefine some deprecated propertiesGravatar wm42016-11-22
| | | | | | | | | | | | | | As threatened by the API changes document. We can actually keep the deprecated --playlist-pos and --cache options, since they are aliases and not used by the corresponding properties. They are inconsistent, but do no harm. Keep them for now for the sake of the command line user. mpv_identify.sh partially stopped working, because it was never updated. The shell magic can't deal with property names that contain "/", so we can't replace "samplerate" with "audio-params/samplerate" - just remove these properties. (How about you use ffprobe?)
* audio: avoid returning audio-device-list entries without descriptionGravatar wm42016-11-14
| | | | | | Use the device name as fallback. This is ugly, but still better than skipping the description entirely. This can be an issue on ALSA, where the API can return entries without proper description.
* command: allow absolute seeks relative to end of streamGravatar Philip Sequeira2016-10-02
| | | | | | "seek -10 absolute" will seek to 10 seconds before the end. This more or less matches the --start option and negative seeks were otherwise useless (they just clipped to 0).
* w32_common: implement VOCTRL_GET_DISPLAY_NAMESGravatar James Ross-Gowan2016-09-29
| | | | | | | | This should make display-names usable on Windows. It returns a list of GDI monitor names like "\\.\DISPLAY1". Since it may be useful to get the monitor that Windows considers associated with the window (with MonitorFromWindow,) this will always be returned as the first argument. This monitor is the one used for display-fps and icc-profile-auto.
* command: add a load-script commandGravatar wm42016-09-22
| | | | | | | The intention is to give libmpv users as much flexibility to load scripts as using mpv from CLI, but without restricting libmpv users from having to decide everything on creation time, or having to go through hacks like recreating the libmpv context to update state.
* command: add a video-dec-params propertyGravatar wm42016-09-20
| | | | | | This is the actual decoder output, with no overrides applied. (Maybe video-params shouldn't contain the overrides in the first place, but damage done.)
