* player/command: add video-codec-info and audio-codec-infoKacper Michajłow9 days1-0/+1
| | | | | | | | | | | Adds support for extracting codec profile. Old properties are redirected to new one and removed from docs. Likely will stay like that forever as there is no reason to remove them. As a effect of unification of properties between audio and video, video-codec will now print codec (format) descriptive name, not decoder long name as it were before. In practice this change fixes what docs says. If you really need decoder name, use the `track-list/N/decoder-desc`.
* common/av_common: clean up mp_lavc_set_extradataJan Ekström2023-03-141-1/+0
| | | | | It no longer has any users, as the last ones (subtitle decoders) were switched to mp_set_avctx_codec_headers.
* common/av_common: constify mp_codec_params related gettersJan Ekström2023-03-141-3/+3
| | | | | | They should not be modifying the argument, so clearly marking it as const makes sure we don't do it in the future as well as allows for read-only optimizations.
* ffmpeg: update to handle deprecation of `av_init_packet`Philip Langdale2022-12-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has been a long standing annoyance - ffmpeg is removing sizeof(AVPacket) from the API which means you cannot stack-allocate AVPacket anymore. However, that is something we take advantage of because we use short-lived AVPackets to bridge from native mpv packets in our main decoding paths. We don't think that switching these to `av_packet_alloc` is desirable, given the cost of heap allocation, so this change takes a different approach - allocating a single packet in the relevant context and reusing it over and over. That's fairly straight-forward, with the main caveat being that re-initialising the packet is unintuitive. There is no function that does exactly what we need (what `av_init_packet` did). The closest is `av_packet_unref`, which additionally frees buffers and side-data. However, we don't copy those things - we just assign them in from our own packet, so we have to explicitly clear the pointers before calling `av_packet_unref`. But at least we can make a wrapper function for that. The weirdest part of the change is the handling of the vtt subtitle conversion. This requires two packets, so I had to pre-allocate two in the context struct. That sounds excessive, but if allocating the primary packet is too expensive, then allocating the secondary one for vtt subtitles must also be too expensive. This change is not conditional as heap allocated AVPackets were available for years and years before the deprecation.
* demux: use no overlapping packets for lossless audiowm42019-09-191-0/+2
| | | | | | Worthless optimization, but at least it justifies that the --audio-backward-overlap option has an "auto" choice. Tested with PCM and FLAC.
* f_lavfi: support setting common filter options like "threads"wm42018-04-291-0/+1
| | | | | | | | | AVFilterContext instances support some additional AVOptions over the actual filter. This includes useful options like "threads". We didn't support setting those for the "direct" wrapper (--vf=yadif:threads=1 failed). Change this. It requires setting options on the AVFilterContext directly, except the code for positional parameters still needs to access the actual filter's AVOptions.
* mp_image: replace rude function with less rude FFmpeg upstream functionwm42018-03-031-3/+0
| | | | This is new, thus a dependency bump is required.
* command: add demuxer-lavf-list propertyRicardo Constantino2018-01-021-0/+1
| | | | | | | | | 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.
* video: properly pass through ICC datawm42017-10-161-0/+3
| | | | | | | | | | | | | | | | | | The same should happen with any other side data that matters to mpv, otherwise filters will drop it. (No, don't try to argue that mpv should use AVFrame. That won't work.) ffmpeg_garbage() is copy&paste from frame_new_side_data() in FFmpeg (roughly feed201849b8f91), because it's not public API. The name reflects my opinion about FFmpeg's API. In mp_image_to_av_frame(), change the too-fragile *new_ref = (struct mp_image){0}; into explicitly zeroing out the fields that are "transferred" to the created AVFrame.
* ad_lavc, vd_lavc: move mpv->lavc decoder parameter setup to common codewm42017-01-251-1/+3
| | | | | | | | 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: drop unused functionwm42017-01-241-1/+0
| | | | Unused since the AVCodecParameters change.
* Remove compatibility thingswm42016-12-071-9/+0
| | | | | | Possible with bumped FFmpeg/Libav. These are just the simple cases.
* ad_lavc, vd_lavc: fix a recent libavcodec deprecation warningwm42016-10-171-0/+9
| | | | | | | | | | | | | | 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.
* video/audio: always provide "proper" timestamps to libavcodecwm42016-08-191-0/+1
| | | | | | | | | | | | | | | | | | | 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.
* demux_lavf, ad_lavc, ad_spdif, vd_lavc: handle FFmpeg codecpar API changewm42016-03-311-0/+2
| | | | | | | | | 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.
* command: add encoder-list propertywm42016-03-011-0/+1
| | | | | Also change decoder-list (for the sake of sharing the underlying code for both properties).
* Relicense some non-MPlayer source files to LGPL 2.1 or laterwm42016-01-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* player: print used number of threads in verbose modewm42015-01-051-1/+1
| | | | Also, don't use av_log() for mpv output.
* Improve setting AVOptionswm42014-08-021-0/+3
| | | | | | | | Use OPT_KEYVALUELIST() for all places where AVOptions are directly set from mpv command line options. This allows escaping values, better diagnostics (also no more "pal"), and somehow reduces code size. Remove the old crappy option parser (av_opts.c).
* stream_lavf: allow setting AVOptions with --stream-lavf-owm42014-07-301-0/+2
| | | | | This commit also creates a private option struct for stream_lavf.c, but since I'm lazy, I'm not moving any existing options to it.
* Factor out setting AVCodecContext extradatawm42014-01-111-0/+1
