* avcodec/h264_metadata_bsf: Allow zeroing constraint_set4_flag and ↵Derek Buitenhuis2021-06-29
| | | | | | | | | | | constraint_set5_flag These bits are reserved in earlier versions of the H.264 spec, and some poor hardware decoders require they are zero. Thus, it is useful to be able to zero these on streams that may have them set. The result is still a valid H.264 bitstream. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* h264_metadata: Support overscan_appropriate_flagMark Thompson2019-07-29
| | | | Fixes #8041.
* vp9_metadata: Improve spec-compliance and warningsAndreas Rheinhardt2019-07-28
| | | | | | | | | | | | | | | | | | The earlier version had three deficits: 1. It allowed to set the stream to RGB although this is not allowed when the profile is 0 or 2. 2. If it set the stream to RGB, then it did not automatically set the range to full range; the result was that one got a warning every time a frame with color_config element was processed if the frame originally had TV range and the user didn't explicitly choose PC range. Now one gets only one warning in such a situation. 3. Intra-only frames in profile 0 are automatically BT.601, but if the user wished another color space, he was not informed about his wishes being unfulfillable. The commit also improves the documentation about this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* dump_extra: Don't add extradata if it already existsAndreas Rheinhardt2019-07-14
| | | | | | | | | | | | | | | | | | | | | The dump_extra bitstream filter currently simply adds the extradata to the packets indicated by the user without checking whether said extradata already exists in the packets. Besides wasting space duplicated extradata in the same packet/access unit is also forbidden for some codecs, e.g. MPEG-2. This check has been added to be able to use the mpeg2_qsv encoder (which only adds the sequence headers to the first packet) in broadcast scenarios where repeating sequence headers are required. The check used here is not perfect: E.g. dump_extra would add the extradata to a H.264 access unit consisting of an access unit delimiter, SPS, PPS and slices. Fixes #8007.

| | | | | | | This is able to modify some header metadata found in the VPS/SPS/VUI, and can also add/remove AUDs. (cherry picked from commit b31a9eae0233325c4b382c657f4b687d5d8b0812)
* lavc: Add h264_redundant_pps bitstream filterMark Thompson2017-10-17
| | | | | | | | | | | This applies a specific fixup to some Blu-ray streams which contain redundant PPSs modifying irrelevant parameters of the stream which confuse other transformations which require correct extradata. A new single global PPS is created, and all of the redundant PPSs within the stream are removed. (cherry picked from commit e6874bc3af2f09af39b5d91b9c5f9ded67459696)
