Stefano Sabatini	63e8d9760f	Use the new libavcore audio channel API. This also allows to remove a linking dependency of libavfilter on libavcodec. Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Benjamin Larsson	62784e3733	Add the CODEC_CAP_CHANNEL_CONF capability code and add 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.

Nick Brereton	0712c230ae	DCA: Occasionally a false XCH sync word can turn up after the core DTS data, 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	15 years ago

Nick Brereton	63c3b716d7	Fix typo in macro name. Patch by Nick Brereton, nick nbrereton net Originally committed as revision 23668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Måns Rullgård	2bb29da602	DCA: indent Originally committed as revision 22872 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	69e171364e	DCA: optimise dca_subsubframe() 8% faster overall on Cortex-A8. Originally committed as revision 22871 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	309d16a4a0	DCA: break out lfe_interpolation_fir() inner loops to a function This enables SIMD optimisations of this function. Originally committed as revision 22861 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	843c7aa8fb	DCA: use FASTDIV in decode_blockcode() Originally committed as revision 22855 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	766fefe8e2	DCA: simplify lfe_interpolation_fir() 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	15 years ago
Måns Rullgård	b92d483bac	DCA: use a local variable for loop boundary 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	15 years ago
Måns Rullgård	0dc7df28dd	DCA: use some type-punning in qmf_32_subbands() Originally committed as revision 22847 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	f462ed1f82	Make synth_filter a function pointer Originally committed as revision 22827 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	38d52f3ea3	DCA: align some arrays 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	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	1429224b04	Move FFT parts from dsputil.h to fft.h Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros 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	15 years ago
Laurent Aimar	4e06acbde4	Fixed a segfault in the DCA decoder with corrupted streams. 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	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

David Conrad	144fec83b3	dca and aac decoders use float_to_int16_interleave, so check for 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	15 years ago
Måns Rullgård	01b2214758	Merge FFTContext and MDCTContext Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	6d9d289e76	DCA: move an aligned array from stack to context Originally committed as revision 19805 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. 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	16 years ago
Kostya Shishkov	0cfa85dd9f	Make VLC tables in DCA decoder use INIT_VLC_USE_NEW_STATIC Originally committed as revision 18643 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	b275500706	Split bitstream.h, put the bitstream writer stuff in the new file put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Carl Eugen Hoyos	e161e007be	Use INIT_VLC_USE_STATIC and not its value "1". Originally committed as revision 18430 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 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	16 years ago
