f1d8763a02 mpegvideo: allocate scratch buffers after linesize is known
Since we can't know which stride a custom get_buffer() implementation is
going to use we have to allocate this scratch buffers after the linesize
is known. It was pretty safe for 8 bit per pixel pixel formats since we
always allocated memory for up to 16 bits per pixel. It broke hoever
with cmdutis.c's alloc_buffer() and high pixel bit depth since it
allocated larger edges than mpegvideo expected.

Fixes fuzzed sample nasa-8s2.ts_s244342.

61c6eef545 h264: prevent decoding of slice NALs in extradata
It is not posible to call get_buffer during frame-mt codec
initialization. Libavformat might pass huge amounts of data as
extradata after parsing broken files. The 'extradata' for the fuzzed
sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains
multiple slices.

706acb558a h264: enable low delay only if no delayed frames were seen
Dropping frames is undesirable but that is the only way by which the
decoder could return to low delay mode. Instead emit a warning and
continue with delayed frames.
Fixes a crash in fuzzed sample nasa-8s2.ts_s20033 caused by a larger
than expected has_b_frames value. Low delay keeps getting re-enabled
from a presumely broken SPS.

1a8c6917f6 h264: avoid stuck buffer pointer in decode_nal_units
When decode_nal_units() previously encountered a NAL_END_SEQUENCE,
and there are some junk bytes left in the input buffer, but no start codes,
buf_index gets stuck 3 bytes before the end of the buffer.

This can trigger an infinite loop in the caller code, eg. in
try_decode_trame(), as avcodec_decode_video() then keeps returning zeroes,
with 3 bytes of the input packet still available.

With this change, the remaining bytes are skipped so the whole packet gets
consumed.

Instead of inlining everything into ff_h264_hl_decode_mb(), use
explicit templating to create versions of the called functions
with constant parameters filled in.  This greatly speeds up
compilation of h264.c and reduces the code size without any
measurable impact on performance.

Compilation time for h264.c on an i7 goes from 30s to 5.5s.
Code size is reduced by 430kB.

Below fixes the maximum reference count check for second reference list in

stringent by
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=dc9ce40069bde3d28f8d0b3e5bd733ae255fecb5)

Probably a silly corner case seldom seen irl, but thought I'd pass along
in case there was interest in correcting the check.

The alternative solutions of checking the index or modifying the VLC tables

The alternative of padding the global tables directly is more ugly and
moving them to the context should benefit cache locality.

1e26a48fa2 h264: fix deadlocks on incomplete reference frame decoding.
If decoding a second complementary field, and the first was
decoded in our thread, mark decoding of that field as complete.
If decoding fails, mark the decoded field/frame as complete.
Do not allow switching between field modes or field/frame mode
between slices within the same field/frame. Ensure that two
subsequent fields cover top/bottom (rather than top/frame,
bottom/frame or such nonsense situations).

Fixes various deadlocks when decoding samples with errors in
reference frames.

Conversion of the luma intra prediction mode to one of the constrained

a crash because we'll call a NULL function pointer for 16x16 block intra
prediction, since constrained intra prediction functions are only
implemented for chroma (8x8 blocks).

beb19a0444 h264: Disallow w/h/pixfmt changes for frame threads.
Previously this was just checked in case of slice threads,
but frame threads do not support this either currently.

Making them support this is of course the long term goal

55b9ef18e4 cabac: split cabac.h into declarations and function definitions
This fixes standalone compilation of some decoders with --disable-optimizations.
cabac.h defines some inline functions that use symbols from cabac.c.  Without
optimizations these inline functions are not eliminated and linking fails with
references to non-existing symbols.

Splitting the inline functions off into their own header and only #including
it in the places where the inline functions are used allows #including cabac.h
from anywhere without ill effects.

Trailing bits are likely to be non-zero if the NAL unit is truncated.

Start code emulation prevention is only required in Annex B bytestream
packed NAL units. For other coding formats the size is already known.
Looking for a start code prefix can result in false positives like in
http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4
which has a false positive in the SPS.

29a29226bb Set avctx->coded_width/height to uncropped h264 sizes
avctx->width/height remain right/bottom cropped as previous behaviour.

Hardware decoders need to know the uncropped data to allocate surfaces
of correct height. Some hardware is picky and fails to decoder properly
if a surface larger than needed is used during decode, so just aligning
up is not enough.

14c21c1ff5 H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock
This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.

eaa21b6870 H264: hotfix for speedloss on frame threading and h264 files with slices.
This fix is not ideal as it still limits the multithreading on field pictures
to the 2nd field only.
Ill try to fix it properly to allow both fields to decode concurrently but this
needs more work.

baad01d8b4 h264: improve checks before calling ff_h264_decode_extradata
The ff_h264_decode_extradata routine now checks for the buffer size
and pointer internally. This makes it possible to remove the external
checks in ff_h264_decode_init.

  In decode_frame there was a size check missing because the buffer
gets tested prior to the invocation of ff_h264_decode_extradata().
