* avcodec/(h263|mpeg4?video)_parser: Make *_find_frame_end() staticAndreas Rheinhardt2021-09-20

* lavc: deprecate AV_CODEC_(FLAG|CAP)_TRUNCATEDAnton Khirnov2021-09-20
| | | | | | | | | | It is supported only by a few decoders (h263, h263p, mpeg(1|2|)video and mpeg4) and is entirely redundant with parsers. Furthermore, using it leads to missing frames, as flushing the decoder at the end does not work properly.

* avcodec/bsf: Unref the packet when flushingAndreas Rheinhardt2021-09-14
| | | | | | | | The documentation does not require the packet to be blank in this case (i.e. it can now contain opaque_ref), but it does contain that the contents will be reset upon success. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/bsf: Use null-bsf for passthrough when availableAndreas Rheinhardt2021-09-14

* avcodec/wmadec: fix WMA gapless playbackbnnm2021-09-12
| | | | | | | | | | | | | Fixes trac issue #7473. Removes encoder delay (skip samples) and writes remaining frame samples after EOF to get correct sample count. Output is now accurate vs players that use Microsoft's codecs (Windows Media Format Runtime). Tested vs encode>decode WMAv2 with MS's codecs and most sample rate/bit rate/channel/mode combinations in ASF/XWMA. WMAv1 appears to use the same delay, from FFmpeg samples.

* avcodec/h274: trim unnecessarily large arrayNiklas Haas2021-09-12
| | | | | | We only ever read to idx+3, so 256 values are overkill. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/h274: don't read from uninitialized array membersNiklas Haas2021-09-12
| | | | | | | | | | | | This bug flew under the radar because, in practice, these values are 0-initialized for the first invocation. But for subsequent invocations (with different h/v values), reading from the uninitialized parts of `out` is undefined behavior. Avoid this by simply adjusting the iteration range of the following loops. Has the added benefit of being a minor speedup. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/libvpxenc: Apply codec options to alpha codec contextAdam Chelminski2021-09-08
| | | | | | | | | | | | | | | | | When encoding yuva420 (alpha) frames, the vpx encoder uses a second vpx_codec_ctx to encode the alpha stream. However, codec options were only being applied to the primary encoder. This patch updates codecctl_int and codecctl_intp to also apply codec options to the alpha codec context when encoding frames with alpha. This is necessary to take advantage of libvpx speed optimizations such as 'row-mt' and 'cpu-used' when encoding videos with alpha. Without this patch, the speed optimizations are only applied to the primary stream encoding, and the overall encoding is just as slow as it would be without the options specified.
