* aacenc: Fix a segfault in search_for_quantizersNathan Caldwell2011-03-08
| | | | | | | | This reverts the removal of scoefs from AACEncContext. It resulted in scoefs being a NULL pointer when search_for_quantizers() is called. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* aac_latm_dec: use aac context and aac m4acThadeu Lima de Souza Cascardo2011-03-07
| | | | | | | | | | | 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. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com> Signed-off-by: Ronald S.

* cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec().Justin Ruggles2011-03-07
| | | | It only has Altivec functions and is not compiled if Altivec is disabled.

* h264_mp3toannexb_bsg: don't crash, but warn, if PPS/SPS not found.Sean McGovern2011-03-07
| | | | | | | | | | 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. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* ac3enc: add num_rematrixing_bands to AC3EncodeContext and use it instead of ↵Justin Ruggles2011-03-04
| | | | | | | | 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.

* threads: allow thread count of zeroMans Rullgard2011-03-02
| | | | | | | | | 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. Signed-off-by: Mans Rullgard <mans@mansr.com>

* pthreads: Fix bug introduced with thread_safe_callbacksAlexander Strange2011-03-01
| | | | | | | | | 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.

* dca: use EXT_AUDIO_ID field to determine core extensionsAnssi Hannula2011-02-24
| | | | | | | | | This avoids the core substream extensions scan when the EXT_AUDIO_ID 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. Signed-off-by: Mans Rullgard <mans@mansr.com>

* VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje2011-02-21

* VC1: inline vc1_put_block() in vc1_decode_i_blocks().Ronald S. Bultje2011-02-21
| | | | | | Advantage is that it allows us to combine several loops into a single one, and these can eventually be merged into the IDCT itself. Also, it allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.
