* Use the new libavcore audio channel API.Stefano Sabatini2010-11-21
| | | | | | | This also allows to remove a linking dependency of libavfilter on libavcodec. Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enumStefano Sabatini2010-11-12
| | | | | | SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add the CODEC_CAP_CHANNEL_CONF capability code and addBenjamin Larsson2010-10-02
| | | | | | | | | that flag to the dca codec. This capability when set will make sure the codec will initialize the channel configuration instead of trusting the container. This fixes issue 2137 and issue 850. Originally committed as revision 25320 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | Patch by Nick Brereton Originally committed as revision 24554 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | Patch by Christophe.Gisquet (gmail) Originally committed as revision 24213 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 24170 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: Occasionally a false XCH sync word can turn up after the core DTS data,Nick Brereton2010-07-05
| | | | | | | | | to verify the sync word the extension fsize field should be compared to the core data length field. Patch by nick.nbrereton@net Originally committed as revision 24054 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: *_bits() -> *_bits_long() where needed, half fix for broken bitstream ↵Benjamin Larsson2010-07-05

| | | | | | Patch by Nick Brereton, nick at nbrereton dot net Originally committed as revision 23698 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | structure Patch by Nick Brereton, nick at nbrereton dot net Originally committed as revision 23694 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix typo in macro name.Nick Brereton2010-06-20
| | | | | | Patch by Nick Brereton, nick nbrereton net Originally committed as revision 23668 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: indentMåns Rullgård2010-04-13
| | | | Originally committed as revision 22872 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: optimise dca_subsubframe()Måns Rullgård2010-04-13
| | | | | | 8% faster overall on Cortex-A8. Originally committed as revision 22871 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: break out lfe_interpolation_fir() inner loops to a functionMåns Rullgård2010-04-12
| | | | | | This enables SIMD optimisations of this function. Originally committed as revision 22861 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: use FASTDIV in decode_blockcode()Måns Rullgård2010-04-12
| | | | Originally committed as revision 22855 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: simplify lfe_interpolation_fir()Måns Rullgård2010-04-12
| | | | | | | | | | This reorders the lfe_fir tables, and drops the mirrored half, such that the loops in lfe_interpolation_fir() can be simplified. The new loop structure should be easier to implement with SIMD. Static data size is reduced by 2kB. 3% faster on Cortex-A8. Originally committed as revision 22849 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: use a local variable for loop boundaryMåns Rullgård2010-04-12
| | | | | | | This prevents gcc reloading the value from memory on each iteration of the loop. Originally committed as revision 22848 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: use some type-punning in qmf_32_subbands()Måns Rullgård2010-04-12
| | | | Originally committed as revision 22847 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make synth_filter a function pointerMåns Rullgård2010-04-10
| | | | Originally committed as revision 22827 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: align some arraysMåns Rullgård2010-04-10
| | | | | | | Optimised implementations of the synth filter will require these arrays 16-byte aligned. Originally committed as revision 22826 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30
| | | | | | is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move FFT parts from dsputil.h to fft.hMåns Rullgård2010-03-06
| | | | Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård2010-03-06
| | | | | | | These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fixed a segfault in the DCA decoder with corrupted streams.Laurent Aimar2010-02-26
| | | | | | | | It happens when the number of channels defined by DCAContext:acmod is lower than DCAContext:prim_channels. In this case, dca_subsubframe() will call qmf_32_subbands() using s->channel_order_tab[] entries equal to -1. Originally committed as revision 22083 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move array specifiers outside DECLARE_ALIGNED() invocationsMåns Rullgård2010-01-22
| | | | Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove unused variable j.Michael Niedermayer2009-10-28
| | | | Originally committed as revision 20398 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split synth filter out of dca.c.Michael Niedermayer2009-10-28
| | | | Originally committed as revision 20396 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix 100l incorrect bitmask check.Reimar Döffinger2009-10-10
| | | | Originally committed as revision 20197 to svn://svn.ffmpeg.org/ffmpeg/trunk
* dca and aac decoders use float_to_int16_interleave, so check forDavid Conrad2009-10-08
| | | | | | | the C version of that rather than float_to_int16. Fixes output on ARM/VFP Originally committed as revision 20192 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Merge FFTContext and MDCTContextMåns Rullgård2009-09-20
| | | | Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCA: move an aligned array from stack to contextMåns Rullgård2009-09-10
| | | | Originally committed as revision 19805 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Support for getting (i)MDCT output multiplied by a constant scaling factor.Siarhei Siamashka2009-05-16
| | | | | | | | Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make VLC tables in DCA decoder use INIT_VLC_USE_NEW_STATICKostya Shishkov2009-04-21
| | | | Originally committed as revision 18643 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename bitstream.h to get_bits.h.Stefano Sabatini2009-04-13
| | | | Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split bitstream.h, put the bitstream writer stuff in the new fileStefano Sabatini2009-04-12
| | | | | | put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use INIT_VLC_USE_STATIC and not its value "1".Carl Eugen Hoyos2009-04-11
| | | | Originally committed as revision 18430 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann2009-04-07
| | | | | | | | | | | AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-01
| | | | | | | Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add support for parsing and decoding DCA-HD streams.Kostya Shishkov2008-11-29
