Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Mans Rullgard	4538729afe	Move sine windows to a separate file These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	b5ec638343	cosmetics: indentation and spacing	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	14 years ago
Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
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

Martin Storsjö	f1a12c76cf	Reindent Originally committed as revision 23603 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Martin Storsjö	f7a30c0baa	nellymoserdec: Allow using unusual input block sizes Originally committed as revision 23602 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
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
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	14b8607065	Add support for hard-coded MDCT-related ff_sine_windows tables. Originally committed as revision 21108 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	b8cef7be5c	nellymoser: use constant seed for dithering RNG Originally committed as revision 20658 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
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
David Conrad	0a8dedc9e1	Use skip_bits_long() for large skips This fixes ogg/theora on ARM (more generally the A32 bitstream reader) Originally committed as revision 18819 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alexander Chemeris	c67d725589	Support 16K samplerate in Nellymoser. patch by Alexander Chemeris, ipse.ffmpeg gmail.com Originally committed as revision 18798 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
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
Stefano Sabatini	9c868219e9	Replace calls to the deprecated function av_init_random() with corresponding calls to av_random_init(). Originally committed as revision 16682 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
