17c99b6158 h2645_parse: handle embedded Annex B NAL units in size prefixed NAL units
Fixes a regression in ca2f19b9cc with some mov/mp4 files. The files have
several NAL units in the supposed single NAL unit after the size field.
Annex B start code prefixes are used to separate them. The first NAL unit
is correctly parsed but the buffer does not point to the next size field.
Instead semi random data (it seems to be the rbsp_stop_one_bit and the
start code prefix) is then parsed as length and will exceed the
remaining length of the buffer.

Patch based on the code in h264's decode_nal_units() and a similar
patch by Hendrik Leppkes in FFmpeg (a9bb4cf87d).

a8cbe5a0cc h264_ps: export actual height in MBs as SPS.mb_height
Currently, SPS.mb_height is actually what the spec calls
PicHeightInMapUnits, which is half the frame height when interlacing is
allowed. Calling this 'mb_height' is quite confusing, and there are at
least two associated bugs where this field is treated as the actual
frame height - in the h264 parser and in the code computing maximum
reordering buffer size for a given level.

Fix those issues (and avoid possible future ones) by exporting the real
frame height in this field.

2866d108c9 vp8dsp: Remove the comment saying that the height is equal to the width
This comment isn't true, the height can be different from the width
for these functions (which is why the height is passed as a parameter
to them).

5f74bd31a9 vp8/armv6: mc: avoid boolean expression in calculation
GNU as evaluates true as '-1' while Apple's variant and llvm's internal
assembler evaluate it as '1'. The best way to avoid this madness is to
eliminate boolean expressions instead of trying to fix it with
preprocessor directives. Use a direct formula to calculate the
required temporary space on the stack in
ff_put_vp8_{epel,bilin}{4,8,16}_h[246]v[246]_armv6().

Fixes a checkasm segfault in vp8dsp.mc when using llvm's internal
assembler for a non-Apple target.

8a62d2c28f vaapi_encode: Maintain a pool of bitstream output buffers
Previously we would allocate a new one for every frame.  This instead
maintains an AVBufferPool of them to use as-needed.

Also makes the maximum size of an output buffer adapt to the frame
size - the fixed upper bound was a bit too easy to hit when encoding
large pictures at high quality.

32c8359093 lavc: export the timestamps when decoding in AVFrame.pts
Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.

Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.
