* avfilter/af_channelmap: fix error message if FL source channel was missingMarton Balint2024-03-241-2/+2
| | | | | | | | FL channel ID is 0, so for an unset value we must check for ID < 0. Regression since 1f96db959c1235bb7079d354e09914a0a2608f62. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/mov_chan: respect channel order when parsing and creating chan atomMarton Balint2024-03-241-253/+211
| | | | | | | | Previously we always assumed that the channels are in native order, even if they were not. The new channel layout API allows us to signal the proper channel order, so let's do so. Fixes ticket #98.
* configure: Explicitly check for static_assert, _Static_assertAndreas Rheinhardt2024-03-241-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C11 provides static assertions via _Static_assert and provides static_assert as a convenience define for this in assert.h. Our codebase uses the latter, as _Static_assert has actually already been deprecated in C23. Not all toolchains that declare support for C11 actually support it; e.g. MSVC 19.27 does not support _Static_assert, but somehow supports static_assert. MSVC 19.27 admits to be a "preview implementation of the ISO C11 standard", so this is not surprising (MSVC 19.28 does not come with this caveat). Furthermore some FATE boxes [1] use old GCC toolchains (with only experimental support for C11) where _Static_assert is supported, but assert.h does not provide the fallback define. They are broken since the first usage of static_assert. This commit therefore checks whether static_assert and _Static_assert work with assert.h included; if not, configure errors out. This intentionally drops support for MSVC 19.27. Users like the old FATE boxes above can still add -Dstatic_assert=_Static_assert to cflags as a workaround if desired.

* avcodec/aom_film_grain: implement AFGS1 parsingNiklas Haas2024-03-232-0/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the AOMedia Film Grain Synthesis 1 (AFGS1) spec: https://aomediacodec.github.io/afgs1-spec/ The parsing has been changed substantially relative to the AV1 film grain OBU. In particular: 1. There is the possibility of maintaining multiple independent film grain parameter sets, and decoders/players are recommended to pick the one most appropriate for the intended display resolution. This could also be used to e.g. switch between different grain profiles without having to re-signal the appropriate coefficients. 2. Supporting this, it's possible to *predict* the grain coefficients from previously signalled parameter sets, transmitting only the residual. 3. When not predicting, the parameter sets are now stored as a series of increments, rather than being directly transmitted. 4. There are several new AFGS1-exclusive fields. I placed this parser in its own file, rather than h2645_sei.c, since nothing in the generic AFGS1 film grain payload is specific to T.35, and to compartmentalize the code base.
* avcodec/aom_film_grain: add AOM film grain synthesisNiklas Haas2024-03-233-0/+925
| | | | | | | | | | | | | | | | | | | Implementation copied wholesale from dav1d, sans SIMD, under permissive license. This implementation was extensively verified to be bit-exact, so it serves as a much better starting point than trying to re-engineer this from scratch for no reason. (I also authored the original implementation in dav1d, so any "clean room" implementation would end up looking much the same, anyway) The notable changes I had to make while adapting this from the dav1d code-base to the FFmpeg codebase include: - reordering variable declarations to avoid triggering warnings - replacing several inline helpers by avutil equivalents - changing code that accesses frame metadata - replacing raw plane copying logic by av_image_copy_plane Apart from this, the implementation is basically unmodified.
* avutil/film_grain_params: add av_film_grain_params_select()Niklas Haas2024-03-234-1/+76
| | | | | | | | Common utility function that can be used by all codecs to select the right (any valid) film grain parameter set. In particular, this is useful for AFGS1, which has support for multiple parameters. However, it also performs parameter validation for H274.
* avutil/frame: clarify AV_FRAME_DATA_FILM_GRAIN_PARAMS usageNiklas Haas2024-03-231-0/+4
| | | | | To allow for AFGS1 usage, which can expose multiple parameter sets for a single frame.
* avcodec/libdavv1d: signal new AVFilmGrainParams membersNiklas Haas2024-03-231-0/+10
| | | | | | Not directly signalled by AV1, but we should still set this accordingly so that users will know what the original intended video characteristics and chroma resolution were.
* avcodec/av1dec: signal new AVFilmGrainParams membersNiklas Haas2024-03-231-0/+10
| | | | | | Not directly signalled by AV1, but we should still set this accordingly so that users will know what the original intended video characteristics and chroma resolution were.
* avcodec/h2645_sei: signal new AVFilmGrainParams membersNiklas Haas2024-03-231-18/+28
| | | | | | H.274 specifies that film grain parameters are signalled as intended for 4:4:4 frames, so we always signal this, regardless of the frame's actual subsampling.
* ffprobe: adapt to new AVFilmGrainParamsNiklas Haas2024-03-231-15/+26
| | | | | Follow the establish convention of printing the bit depth metadata per-component.

|
* avutil/film_grain_params: add metadata to common structNiklas Haas2024-03-233-4/+62
| | | | | | | | | | | | This is needed for AV1 film grain as well, when using AFGS1 streams. Also add extra width/height and subsampling information, which AFGS1 cares about, as part of the same API bump. (And in principle, H274 should also expose this information, since it is needed downstream to correctly adjust the chroma grain frequency to the subsampling ratio) Deprecate the equivalent H274-exclusive fields. To avoid breaking ABI, add the new fields after the union; but with enough of a paper trail to hopefully re-order them on the next bump.

| | | | | | | | AVOutputFormat has default codecs for audio, video and subtitle and often these are the only codecs of this type allowed. So add a flag to AVOutputFormat so that this can be checked generically. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Enforce one-stream limit where appropriateAndreas Rheinhardt2024-03-2219-4/+41
| | | | | | | | | | Several muxers (e.g. pcm muxers) did not check the number of streams even though the individual streams were not recoverable from the muxed files. This commit changes this by using the FF_OFMT_MAX_ONE_OF_EACH flag where appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mux: Add flag for "not more than one stream of each type"Andreas Rheinhardt2024-03-2238-237/+239
| | | | | | | | | | | | | | | | More exactly: Not more than one stream of each type for which a default codec (i.e. AVOutputFormat.(audio|video|subtitle)_codec) is set; for those types for which no such codec is set (or for which no designated default codec in AVOutputFormat exists at all) no streams are permitted. Given that with this flag set the default codecs become more important, they are now set explicitly to AV_CODEC_ID_NONE for "unset"; the earlier code relied on AV_CODEC_ID_NONE being equal to zero, so that default static initialization set it accordingly; but this is not how one is supposed to use an enum.

* fate/filter-audio: Don't use pcm output for channelsplit testAndreas Rheinhardt2024-03-222-4/+4
| | | | | | | | | | | This test muxes two streams into a single pcm file, although the two streams are of course not recoverable from the output (unless one has extra information). So use the streamhash muxer instead (which also provides coverage for it; it was surprisingly unused in FATE so far). This is in preparation for actually enforcing a limit of one stream for the PCM muxers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mux_utils: Don't report that AV_CODEC_ID_NONE can be muxedAndreas Rheinhardt2024-03-221-3/+4
| | | | | | | | If AVOutputFormat.video_codec, audio_codec or subtitle_codec is AV_CODEC_ID_NONE, it means that there is no default codec for this format and not that it is supported to mux AV_CODEC_ID_NONE. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
