CVE-2011-3895

Signed-off-by: Reinhard Tartler <siretart@tauware.de>

This fixes a segfault on startup.

Also remove a commented-out and completely unused variable.

the previous documentation indicated how many bytes are read from the input,
not how many samples are read.

The fate reference is updated because the previous test skipped a sample in
each encode() call due each input frame having an odd number of samples.

Fixes --disable-everything --enable-decoder=h264 --disable-optimizations.

This fixes some timecode probing in MOV.

The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly)
a MpegEncContext in their private context. Since they do not call the
common mpegvideo init function slice_context_count has explicitly set
to 1.
Prevents a null pointer dereference in the h264 parser and fixes
bug 193.

removed in 98df93c, this makes the documentation correct again.

    	x86: cabac: replace explicit memory references with "m" operands

    	This replaces the explicit offset(reg) memory references with
    	"m" operands for the same locations.  As a result, one fewer
    	register operand is needed for these inline asm statements.

This change appears to have broken compilation on darwin, and subsequent
fixes by martin (which did not fix compilation) removed the register
advantage, thus this change seems not a good idea to keep.

This issue was discovered while decoding the FATE sample vqa/ws_snd.vqa.
For some unknown reason only audio decoding is tested by FATE for that file,
but not video.

Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

Check explicitly if enough bits are left to prevent an infinite loop
