* dsputil: add bswap16_buf()Mans Rullgard2011-03-16
| | | | | | | | There are several places where a buffer is byte-swapped in 16-bit units. This allows them to share code which can be optimised for various architectures. Signed-off-by: Mans Rullgard <mans@mansr.com>

* mathops: fix MULL() when the compiler does not inline the function.Justin Ruggles2011-03-15
| | | | | | | If the function is not inlined, an immmediate cannot be used for the shift parameter, so the %cl register must be used instead in that case. This fixes compilation for x86-32 using gcc with --disable-optimizations.
* mathops: change "g" constraint to "rm" in x86-32 version of MUL64().Justin Ruggles2011-03-15
| | | | | The 1-arg imul instruction cannot take an immediate argument, only a register or memory argument.
* mathops: convert MULL/MULH/MUL64 to inline functions rather than macros.Justin Ruggles2011-03-15
| | | | | | This fixes unexpected name collisions that were occurring with variables declared within the macros. It also fixes the fate-acodec-ac3_fixed regression test on x86-32.

* ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.Justin2011-03-14
| | | | | | | | | This increases the accuracy of coefficients, leading to improved quality. Rescaling of the coefficients to full 25-bit accuracy is done rather than offsetting the exponent values. This requires coefficient scaling to be done before determining the rematrixing strategy. Also, the rematrixing strategy calculation must use 64-bit math to prevent overflow due to the higher precision coefficients.
* mm decoder: move buffer allocation from decode_init() to decode_frame()Peter Ross2011-03-14

* VP8: optimize VP8Context struct orderingJason Garrett-Glaser2011-03-12
| | | | | 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.

* VP8: token probs doesn't need paddingJason Garrett-Glaser2011-03-12
| | | | | prob[0] is the only prob array ever accessed, so prob[1] can serve as padding for prob[0].
* VP8: use a goto to break out of two loopsJason Garrett-Glaser2011-03-12
| | | | | 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.

* 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.

* 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>

* 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.
