* avformat/mux: Rename FF_FMT_ALLOW_FLUSH->FF_OFMT_FLAG_ALLOW_FLUSHAndreas Rheinhardt2024-03-2211-28/+36

* avutil/frame: Rename av_frame_side_data_get and add wrapper for itAndreas Rheinhardt2024-03-226-19/+31
| | | | | | | | | | | | | | | | | | | av_frame_side_data_get() has a const AVFrameSideData * const *sd parameter; so calling it with an AVFramesSideData **sd like AVCodecContext.decoded_side_data (or with a AVFramesSideData * const *sd) is safe, but the conversion is not performed automatically in C. All users of this function therefore resort to a cast. This commit changes this: av_frame_side_data_get() is renamed to av_frame_side_data_get_c(); furthermore, a static inline wrapper for it name av_frame_side_data_get() is added that accepts an AVFramesSideData * const * and converts this to const AVFramesSideData * const * in a Wcast-qual safe way. This also allows to remove the casts from the current users. Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/libx265: Pass logctx as void*, not AVClass**Andreas Rheinhardt2024-03-221-3/+3
| | | | | | | | | | | | | | | | The latter need not be save, because av_log() expects to get a pointer to an AVClass-enabled structure and not only a fake object. If this function were actually be called in the following way: const AVClass *avcl = avctx->av_class; handle_mdcv(&avcl, ); the AVClass's item_name would expect to point to an actual AVCodecContext, potentially leading to a segfault.

* avcodec/libx265: Don't use AVBPrint unnecessarilyAndreas Rheinhardt2024-03-221-25/+6
| | | | | | | | | | | | | | | | | | This code uses the AVBPrint API for exactly one av_bprintf() in a scenario in which a good upper bound for the needed size of the buffer is available (with said upper bound being much smaller than sizeof(AVBPrint)). So one can simply use snprintf() instead. This also avoids the (always-false due to the current size of the internal AVBPrint buffer) check for whether the AVBPrint is complete. Furthermore, the old code used AV_BPRINT_SIZE_AUTOMATIC which implies that the AVBPrint buffer will never be (re)allocated and yet it used av_bprint_finalize(). This has of course also been removed.

| | | | | | | | | | | | AVCodecContext extradata should be an AVCDecoderConfigurationRecord when bitstream format is avcc. Simply concatenating the NALUs output by x264_encoder_headers does not form a standard AVCDecoderConfigurationRecord.

* avcodec/libx265: add support for writing out CLL and MDCVJan Ekström2024-03-203-0/+110
| | | | | | | The newer of these two are the separate integers for content light level, introduced in 3952bf3e98c76c31594529a3fe34e056d3e3e2ea , with X265_BUILD 75. As we already require X265_BUILD of at least 89, no further conditions are required.
* avcodec/libx264: add support for writing out CLL and MDCVJan Ekström2024-03-204-0/+102
| | | | | | | | | | | | Both of these two structures were first available with X264_BUILD 163, so make relevant functionality conditional on the version being at least such. Keep handle_side_data available in all cases as this way X264_init does not require additional version based conditions within it. Finally, add a FATE test which verifies that pass-through of the MDCV/CLL side data is working during encoding.
* avcodec/libsvtav1: add support for writing out CLL and MDCVJan Ekström2024-03-203-0/+88
| | | | | | | | | | | | These two were added in 28e23d7f348c78d49a726c7469f9d4e38edec341 and 3558c1f2e97455e0b89edef31b9a72ab7fa30550 for version 0.9.0 of SVT-AV1, which is also our minimum requirement right now. In other words, no additional version limiting conditions seem to be required. Additionally, add a FATE test which verifies that pass-through of the MDCV/CLL side data is working during encoding.

* lavc/vvc: Fix check whether QG is in first tile colFrank Plowman2024-03-201-1/+1
| | | | | | | | | | | The second part of this condition is intended to check whether the current quantisation group is in the first CTU column of the current tile. The issue is that ctb_to_col_bd gives the x-ordinate of the first column of the current tile *in CTUs*, while xQg gives the x-ordinate of the quantisation group *in samples*. Rectify this by shifting xQg by ctb_log2_size to get xQg in CTUs before comparing. Fixes FFVVC issues #201 and #203.

* ffmpeg: set extra_hw_frames to account for frames held in queuesMark Thompson2024-03-193-1/+40
| | | | | | | | | | Since e0da916b8f5b079a4865eef7f64863f50785463d the ffmpeg utility has held multiple frames output by the decoder in internal queues without telling the decoder that it is going to do so. When the decoder has a fixed-size pool of frames (common in some hardware APIs where the output frames must be stored as an array texture) this could lead to the pool being exhausted and the decoder getting stuck. Fix this by telling the decoder to allocate additional frames according to the queue size.

* avcodec/mpeg12dec: extract only one type of CC substreamMarth642024-03-191-3/+61
| | | | | | | | | | | | | | | | | | | | | In MPEG-2 user data, there can be different types of Closed Captions formats embedded (A53, SCTE-20, or DVD). The current behavior of the CC extraction code in the MPEG-2 decoder is to not be aware of multiple formats if multiple exist, therefore allowing one format to overwrite the other during the extraction process since the CC extraction shares one output buffer for the normalized bytes. This causes sources that have two CC formats to produce flawed output. There exist real-world samples which contain both A53 and SCTE-20 captions in the same MPEG-2 stream, and that manifest this problem. Example of symptom: THANK YOU (expected) --> THTHANANK K YOYOUU (actual) The solution is to pick only the first CC substream observed with valid bytes, and ignore the other types. Additionally, provide an option for users to manually "force" a type in the event that this matters for a particular source. Signed-off-by: Marth64 <marth64@proxyid.net>
