* avcodec/hevc_ps: add proper bound checks around cm_ref_layer_id in ↵HEADmasterClement Lecigne2023-05-172-7/+17
| | | | | | | colour_mapping_table. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: James Almer <jamrial@gmail.com>
* av1_parse: Don't reject zero-size padding OBUsMark Thompson2023-05-171-1/+3
| | | | Padding OBUs are not required to be nonempty.
* av1_parse: Remove unused getbits instanceMark Thompson2023-05-172-8/+1
|
* cbs_av1: Don't reject unknown metadataMark Thompson2023-05-173-2/+38
| | | | | | | Accept it and pass it through unchanged. The standard requires that decoders ignore unknown metadata, and indeed this is tested by some of the Argon coverage streams.
* cbs_av1: Add tracing headers for metadata typesMark Thompson2023-05-171-0/+10
| | | | Make it a little easier to interpret metadata in trace output.

* avcodec/vdpau_mpeg4: fix order of quant matrix coefficientsHendrik Leppkes2023-05-151-2/+3
| | | | | | The matrix coefficients are stored permutated for the IDCT, rather then in plain raster order, and need to be un-permutated for the hardware.

* lavc/libdav1d: fix exporting framerateAnton Khirnov2023-05-152-7/+5
| | | | Same issues as in the previous commit.
* lavc/av1*: fix exporting framerateAnton Khirnov2023-05-155-15/+29
| | | | | | | | | * take num_ticks_per_picture_minus_1 into account, since that is a part of the framerate computation * stop exporting num_ticks_per_picture_minus_1 into AVCodecContext.ticks_per_frame, as that field is used for other purposes (in conjunction with repeat_pict, which is not used at all by av1)
* lavc: deprecate AVCodecContext.ticks_per_frameAnton Khirnov2023-05-1527-23/+158
| | | | | | | | For encoding, this field is entirely redundant with AVCodecContext.framerate. For decoding, this field is entirely redundant with AV_CODEC_PROP_FIELDS.
* lavc/libvpxenc: send frame durations to the encoderAnton Khirnov2023-05-151-2/+13
| | | | | Adapt similar code from libaomenc - stop using ticks_per_frame except as a last resort.
* lavc/libkvazaar,libopenh264enc: drop redundant checksAnton Khirnov2023-05-152-10/+0
| | | | The same check is present in encode_preinit_video().
* libaomenc: use AVCodecContext.framerate when availableAnton Khirnov2023-05-151-2/+6

* lavc/msmpeg4enc: use AVCodecContext.framerate when availableAnton Khirnov2023-05-151-1/+7
|
* lavc/ratecontrol: use AVCodecContext.framerate when availableAnton Khirnov2023-05-151-0/+3
|
* lavf: use AV_CODEC_PROP_FIELDS where appropriateAnton Khirnov2023-05-152-3/+3
| | | | | | | | | | H.264 and mpeg12 parsers need to be adjusted at the same time to stop using the value of AVCodecContext.ticks_per_frame, because it is not set correctly unless the codec has been opened. Previously this would result in both the parser and lavf seeing the same incorrect value, which would cancel out. Updating lavf and not the parsers would result in correct value in lavf, but the wrong one in parsers, which would break some tests.
* lavc/codec_desc: add a property for codecs that support field codingAnton Khirnov2023-05-153-5/+19
| | | | | | | Multiple places currently use AVCodecContext.ticks_per_frame > 1 to identify such codecs, which * requires a codec context * requires it to be open
* lavc: deprecate AV_CODEC_CAP_SUBFRAMESAnton Khirnov2023-05-1519-24/+98
| | | | There is nothing meaningful the caller can do with it.
* lavc/decode: drop a useless warningAnton Khirnov2023-05-152-9/+0
| | | | | | | | | | Decoders will currently warn if an audio decoder not marked with AV_CODEC_CAP_SUBFRAMES consumes less than the whole packet, but * this happens for regular files * this has no negative consequences * there is no meeaningful action that can or should be taken in response The warning is thus useless noise.
* avcodec/cbs_av1: add valid range of values for num_units_in_decoding_tickJames Almer2023-05-141-1/+1

* libavcodec/libsvtav1: Allow -1 for preset optionChristopher Degawa2023-05-111-2/+2

* lavc/tak: do not store invalid values in stream infoAnton Khirnov2023-05-051-7/+13
| | | | | | | | | | When tak_get_nb_samples() fails, it will currently write AVERROR_INVALIDDATA as TAKStreamInfo.frame_samples. The parser will then use this negative value as a frame duration, which leads to various breakage. Avoid this by returning the error code from tak_parse_streaminfo() directly; never store negative values in the parsed header.

* lavf/dv: use a more granular timebase for audioAnton Khirnov2023-05-021-0/+3
| | | | | | | | | | | | | One that is fine enough to represent all DV audio sample rates. Audio packet durations are now sample-accurate. This largely undoes commit 76fbb0052df471075858c1cb82b04c8be7adba8d. To avoid breaking the issue fixed by that commit, resync audio timestamps against video if they get more than one frame apart. The sample from issue #8762 still works correctly after this commit. Slightly changes the results of the lavf-dv seektest, due to the audio timebase being more granular.
