2013-07-09imc: Catch a division by zeroLuca Barbato
Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-03-14avcodec: av_log_ask_for_sample() ---> avpriv_request_sample()Diego Biurrun
2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-02-12imc/iac: decode directly to the user-provided AVFrameJustin Ruggles
2013-02-09dsputil: Move LOCAL_ALIGNED macros to libavutilDiego Biurrun
2013-01-22floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje
This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-11-11Include libavutil/channel_layout.h instead of libavutil/audioconvert.hJustin Ruggles
Also reorder some other #include when applicable.
2012-11-01imc: set channels to 1 instead of validating itJustin Ruggles
2012-10-01iac/imc: use planar sample formatJustin Ruggles

2012-10-01avcodec: Drop some silly commented-out av_log() invocationsDiego Biurrun

2012-08-06imc: fix size of a memset()Mans Rullgard
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>

2012-06-09iac: generate codec tables as they are supposed to beKostya Shishkov
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.

2012-06-05imc: make IMDCT support stereo outputKostya Shishkov
This will be useful for Indeo Audio decoder which is almost the same but supports stereo.
2012-06-05imc: move channel-specific data into separate contextKostya Shishkov
This will be useful for Indeo Audio decoder which is almost the same but supports stereo.

2012-04-06cosmetics: Align codec declarationsMartin Storsjö
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>

2011-12-17get_bits: remove A32 variantMans Rullgard
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>
2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
2011-11-03imc: return error codes instead of 0 for error conditions.Justin Ruggles
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.
2011-11-03imc: return meaningful error codes instead of -1Justin Ruggles
2011-11-03imc: do not set channel layout for stereoJustin Ruggles
we only support decoding of mono imc
2011-11-03imc: validate channel countJustin Ruggles
ask for a sample if not mono
2011-11-03imc: check for ff_fft_init() failureJustin Ruggles
2011-11-03imc: check output buffer size before decodingJustin Ruggles
2011-11-03imc: use DSPContext.bswap16_buf() to byte-swap packet dataJustin Ruggles

2011-03-20Move sine windows to a separate fileMans Rullgard
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>
2011-03-19fft: remove inline wrappers for function pointersMans Rullgard
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>

2011-02-15Merge libavcore into libavutilReinhard Tartler
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.

2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-08-19imc: fix undefined float to int conversionMåns Rullgård
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

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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
