Personnal guess is Diego Biurrun.
After seek, s->duration need recalculation, AVCodecParserContext need be set
again. Without the fix, the first audio packet would be dropped after
compute_pkt_fields() as the final pts/dts become invalid.

Allow supporting files for which the image stride is smaller than
the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9
file or a 16x16 VP8 file with -fflags +emu_edge.
This is necessary to avoid target config settings bleeding into the host
compilation process with hardcoded tables and the DV VLC tables no longer
present as static tables in a header file.

The not handling of frame gaps has lead to the lack of a dummy reference
frame, which has lead to the failure of decode_slice_header() which has
lead to one SEI recovery message being skiped which had introduced a
slightly suboptimal recovery point for at least 1 h264 file compared to
JM.

We have a qemu based fate alpha client. And various failures
on alpha have previously pointed to issues in generic C code.
Thus IMHO it makes sense to keep alpha code as long as someone
is willing to do the little bit of maintaince it needs

XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.
This allows for updating metadata from new metadata packets in the
middle of a stream (e.g., MPD streams). There still needs to be a signal
that there *is* new metadata, but this is at least gets the data into a
data structure.

Fix coordinates of the lower right corner of the text area.
Note that the coordinates are redundant as the size and
position of the text area are known.
Many decoders (including Sony Playstation 3, VLC and FFmpeg)
ignore the redundant coordinates.
Some hardware decoders need them for correct playback.
Verified on Philips DVD player models HTS7201 and DVP3380.

return them to the user on the next calls to avcodec_decode_subtitle2.

pthread: drop avcodec_ prefixes from static functions
Merged-by: Michael Niedermayer <michaelni@gmx.at>
There are instructions pavgb and pavgusb. Both instructions do the same
operation but they have different enconding. Pavgb exists in SSE (or
MMXEXT) instruction set and pavgusb exists in 3D-NOW instruction set.
livavcodec uses the macro PAVGB to select the proper instruction. However,
the function avg_pixels8_xy2 doesn't use this macro, it uses pavgb
directly.
As a consequence, the function avg_pixels8_xy2 crashes on AMD K6-2 and
K6-3 processors, because they have pavgusb, but not pavgb.
This bug seems to be introduced by commit
