Issues with the code: 1) The skip_bits_long breaks packed B-frames since we skip of the packed frame, even for VDPAU. 2) Calling ff_h263_find_resync_marker_reverse is nonsense for MPEG-4, and for H.263 the only code using this (vaapi_mpeg4) explicitly reverts this change! 3) mb_x/mb_y are always 0 when vaapi_mpeg4_decode_slice, so doing computations with them is just obfuscation 4) due to not updating mb_y the code would always go into the error resilience case, causing nonsense error messages and maybe further issues. While tested to fix the data provided to the decoder in case of VDPAU so it is the same as for the non-hwaccel code, the VA-API code was not tested to still work, and adding regression testing even as a quick hack is much more complicated for it.

Currently the code can in some cases draw tiles that hang outside the allocated buffer. This patch increases the buffer size to avoid out of array accesses. An alternative would be to fail if such tiles are encountered. I do not know if any valid files use such hanging tiles. Fixes Ticket2971 Found-by: ami_stuff Signed-off-by:

Use it only on subtitle CuePoints. With proper demuxer/splitter support this should improve the display of subtitles right after seeking to a given point in the stream. Signed-off-by:

Avoid overwriting the bitstream buffer data before we have ended processing the frame. This is necessary to fix hwaccels which might try to use the buffer during the end_frame call. I am not sure but it is possible this could even trigger a use-after-free if the av_fast_malloc allocated a new buffer. This would require that decode_slice did not wind the bitstream forward all the way to the end, which does not currently happen in normal streams. Signed-off-by:

The specification does not allow multiple bits to be set, but some encoders do it anyway. Applying it only to the first seems to give better results. Signed-off-by:
