Mans Rullgard	bc90230b98	imc: fix size of a memset() IMCContext was changed from an array to a pointer in `66b84e4`, but this memset() was not updated. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Paul B Mahol	137e80817d	lavc: build some codecs only if they are actually enabled Saves few bytes if only some of them in same file are enabled. Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Kostya Shishkov	cac4760bf4	iac: generate codec tables as they are supposed to be Unlike its predecessor, Indeo Audio codec generates tables depending on sampling rate. Previously decoder used pre-generated tables for 22050 Hz which obviously doesn't work with other frequencies. Many thanks to Maxim Poliakovsky for providing all needed information for this.	13 years ago
Kostya Shishkov	c6061443f7	Indeo Audio decoder	13 years ago
Kostya Shishkov	34271cabac	imc: make IMDCT support stereo output This will be useful for Indeo Audio decoder which is almost the same but supports stereo.	13 years ago
Kostya Shishkov	c45e2da617	imc: move channel-specific data into separate context This will be useful for Indeo Audio decoder which is almost the same but supports stereo.	13 years ago
Kostya Shishkov	d073f122ea	imc: some cosmetics	13 years ago
Kostya Shishkov	f05b69a79f	fix typo in comment	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	a1e98f198e	get_bits: remove A32 variant The A32 bitstream reader variant is only used on ARMv5 and for Prores due to the larger bit cache this decoder requires. In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only statistically significant difference between ALT and A32 is a 4% advantage for ALT in FLAC decoding. There is thus no (longer) any reason to keep the A32 reader from this point of view. This patch adds an option to the ALT reader increasing the bit cache to 32 bits as required by the Prores decoder. Benchmarking shows no significant change in speed on Intel i7. Again, the A32 reader fails to justify its existence. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	a4998e448f	imc: return error codes instead of 0 for error conditions. This fixes a bug where the whole buffer was returned as decoded audio due to *data_size not being set to zero and the return value being >= 0.	13 years ago
Justin Ruggles	08e5cd3810	imc: return meaningful error codes instead of -1	13 years ago
Justin Ruggles	0473f29b60	imc: do not set channel layout for stereo we only support decoding of mono imc	13 years ago
Justin Ruggles	7b7f47e733	imc: validate channel count ask for a sample if not mono	13 years ago
Justin Ruggles	95fee70d67	imc: check for ff_fft_init() failure	13 years ago
Justin Ruggles	86962b13f6	imc: check output buffer size before decoding	13 years ago
Justin Ruggles	e9362aaedf	imc: use DSPContext.bswap16_buf() to byte-swap packet data	13 years ago
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
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	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.

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
Måns Rullgård	dd5f3238c1	imc: fix undefined float to int conversion Conversion of an out of range float to int is undefined. Clipping to the final range first avoids such problems. This fixes decoding on MIPS, which handles these conversions differently from many other CPUs. Originally committed as revision 24838 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	66b84e4ab2	Make Intel Music Coder output SAMPLE_FMT_FLT Originally committed as revision 24267 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
