Jason Garrett-Glaser 1eeca88691 VP8: optimize VP8Context struct ordering 
Shaves at least 3KB off code size on x86, should improve cache utilization.
This would probably be useful to do for other decoders/encoders as well.

Jason Garrett-Glaser b1d2f812c9 VP8: token probs doesn't need padding 
prob[0] is the only prob array ever accessed, so prob[1] can serve as padding
for prob[0].

Jason Garrett-Glaser 628b48db85 VP8: use a goto to break out of two loops 
A break statement was supposed to break out of two loops, but only broke out of one.
Didn't affect output, just could have been marginally slower.

Nathan Caldwell 31ff9bd7b8 aacenc: Fix a segfault in search_for_quantizers 
This reverts the removal of scoefs from AACEncContext.
It resulted in scoefs being a NULL pointer when
search_for_quantizers() is called.

Thadeu Lima de Souza Cascardo 36864ac354 aac_latm_dec: use aac context and aac m4ac 
When decoding latm config, use the corresponding aac context and its
m4ac instead of using NULL and a local variable. This fixes decoding of
audio in MPEG TS from SBTVD (the Brazillian Digital TV Sytem), when
there is no extradata. This is the case when using the decoder with
gst-ffmpeg and a GStreamer mpegts demuxer.

Sean McGovern 02dd3666c2 h264_mp3toannexb_bsg: don't crash, but warn, if PPS/SPS not found. 
Should an AVC-1 in MP4 stream not contain SPS or PPS NAL units,
this BSF is then unable to allocate an output buffer for the
modified stream. Warn that the resulting stream may be unplayable.

Fix roundup issue #2386.

Justin Ruggles 53e35fd340 ac3enc: add num_rematrixing_bands to AC3EncodeContext and use it instead of the hardcoded value. 
Currently it is always 4, but this change will allow it to be adjusted when
bandwidth-related features are added such as channel coupling, enhanced
channel coupling, and spectral extension.

Mans Rullgard ff1efc524c threads: allow thread count of zero 
This moves setting the thread count to a minimum of 1 to
frame_thread_init(), allowing a value of zero to propagate
through to the codec if frame threading is not used.  This
makes auto-threads work in libx264.

Alexander Strange ad9791e12b pthreads: Fix bug introduced with thread_safe_callbacks 
For intra codecs, ff_thread_finish_setup() is called before decoding starts
automatically. However, get_buffer can only be used before it's called, so
adding this requirement broke frame threading for them. Fixed by moving the
call until after get_buffer is finished.

field indicates no extensions or only unsupported extensions. The scan
is done only if the value of EXT_AUDIO_ID is unknown or indicates a
present XCh extension which we can decode.
