Nathan CaldwellandRonald S. Bultje 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 CascardoandRonald S. Bultje 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 McGovernandRonald S. Bultje 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 StrangeandRonald S. Bultje 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.
