* lavc: AV-prefix all codec flagsVittorio Giovara2015-07-27
| | | | | | Convert doxygen to multiline and express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavc: Replace av_dlog and tprintf with internal macrosVittorio Giovara2015-04-19
|
* lavc: remove unused traces of fmtconvert usageAnton Khirnov2015-02-28
| | | | | Those decoders have been switched to float output and so do not use fmtconvert anymore.
* wma: check memory allocations and propagate errorsVittorio Giovara2014-12-18

* build: Split WMA frequencies into a separate object fileDiego Biurrun2014-09-04
| | | | | These are the only WMA bits shared with binkaudio. Splitting them off reduces the binnkaudio dependency on general WMA code.

* avcodec: Add av_cold attributes to init functions missing themDiego Biurrun2013-05-04
|
* lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruftAnton Khirnov2013-03-09

* wmaenc: alloc/free coded_frame instead of keeping it in the WMACodecContextJustin Ruggles2013-02-12
|
* floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.
* wma: do not keep private copies of some AVCodecContext fieldsJustin Ruggles2012-11-01
| | | | | channels, sample_rate, bit_rate, and block_align can be used directly from the AVCodecContext
* wmaenc: use float planar sample formatJustin Ruggles2012-10-06
|
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07
|
* wma: Lower the maximum number of channels to 2Martin Storsjö2012-07-01
| | | | | | | | | | | 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>

* wma: Clip WMA1 and WMA2 frame length to 11 bits.Alex Converse2012-01-25
| | | | | | | | | | | | 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
* wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits.Justin Ruggles2011-11-22
| | | | | | | | 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.
* Move sine windows to a separate fileMans Rullgard2011-03-20
| | | | | | | 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>
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-02
| | | | | | | 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>
