* avcodec/h264_mp4toannexb: Prepend SPS/PPS to buffering period SEIJosh Allmann2024-08-141-0/+15
| | | | | | | | | | | | | Encoders may emit a buffering period SEI without a corresponding SPS/PPS if the SPS/PPS is carried out-of-band, eg with avcc. During Annex B conversion, this may result in the SPS/PPS being inserted *after* the buffering period SEI but before the IDR NAL. Since the buffering period SEI references the SPS, the SPS/PPS needs to come first. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* avcodec/h265_metadata: Add options to set width/height after cropZhao Zhili2024-06-071-3/+98
| | | | | | | | | | It's a common usecase to request a video size after crop. Before this patch, user must know the video size before crop, then set crop_right/crop_bottom accordingly. Since HEVC can have different CTU size, it's not easy to get/deduce the video size before crop. With the new width/height options, there is no such requirement.

* avcodec/adts_header: Add ff_adts_header_parse_buf()Andreas Rheinhardt2024-05-201-4/+2
| | | | | | | | | | | | Most users of ff_adts_header_parse() don't already have an opened GetBitContext for the header, so add a convenience function for them. Also use a forward declaration of GetBitContext in adts_header.h as this avoids (implicit) inclusion of get_bits.h in some of the users that now no longer use a GetBitContext of their own.

| | | | | | | This reverts commit 41b73ae883ec2a70c814e394de0e5ae5f1f13e87. This patch was pushed extremely quickly, without giving developers the time to object.
* bsf: use standard include pathsAndrew Kelley2024-04-0944-186/+184
| | | | | | | | | | | | | | Removes the special -I flag specified in the avcodec/bsf/ subdirectory. This makes code copy-pastable to other parts of the ffmpeg codebase, as well as simplifying the build script. It also reduces ambiguity, since there are many instances of same-named header files existing in both libavformat/ and libavcodec/ subdirectories.

Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/bsf/mp3_header_decompress: Remove BSFAndreas Rheinhardt2024-03-022-131/+0
| | | | | | | | | | | | | | | | | This BSF is supposed to be used in conjunction with mp3_header_compress, which has been removed more than ten years ago in commit c6080d89009056530119ab794ad02e4d515c7754. It mangled the headers by removing the CRC field as well as fields that are supposed to stay constant for the entirety of a stream (which are put into extradata). This made these files unplayable; they need to be decompressed with the BSF first (which does not happen automatically). Even in this case the CRC does not get restored. I am not aware that such compressed files exist at all; therefore this commit removes the BSF completely.
