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

Reimar Döffinger	268fcbe2c8	Fix 100l incorrect bitmask check. Originally committed as revision 20197 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	16 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	16 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

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
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. 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	16 years ago
