2013-05-04avcodec: Add av_cold attributes to init functions missing themDiego Biurrun
2013-03-09lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruftAnton Khirnov
2013-02-12wmaenc: alloc/free coded_frame instead of keeping it in the WMACodecContextJustin Ruggles
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.
2012-11-01wma: do not keep private copies of some AVCodecContext fieldsJustin Ruggles
channels, sample_rate, bit_rate, and block_align can be used directly from the AVCodecContext
2012-10-06wmaenc: use float planar sample formatJustin Ruggles
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-07-01wma: Lower the maximum number of channels to 2Martin Storsjö
ff_wma_init is used only by wmadec and wmaenc, and neither of them can handle more than 2 channels. This fixes crashes with invalid files. Based on patch by Piotr Bandurski and Michael Niedermayer. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-03-07wma: Refactor common code to fix standalone compilation of WMA lossless decoder.Diego Biurrun

2012-01-26wma: Clip WMA1 and WMA2 frame length to 11 bits.Alex Converse
The MDCT buffers in the decoder are only sized for up to 11 bits. The reverse engineered documentation for WMA1/2 headers say that that for all samplerates above 32kHz 11 bits are used. 12 and 13 bit support were added for WMAPro. I was unable to make any Microsoft tools generate a test file at a samplerate above 48kHz. Discovered by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2011-11-22wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits.Justin Ruggles
The initial values are not checked against the number of block sizes. Initializing them to frame_len_bits will result in a block size index of 0 in these cases instead of something that might be out-of-range. Fixes Bug 81.
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>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-02Separate format conversion DSP functions from DSPContext.Justin Ruggles
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>
