Anton Khirnov	f073b1500e	lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruft	12 years ago
Justin Ruggles	205a95f7b5	wmaenc: alloc/free coded_frame instead of keeping it in the WMACodecContext	12 years ago
Michael Niedermayer	984add64a4	wma: check byte_offset_bits Fixes assertion failure Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	5959bfaca3	floatdsp: move butterflies_float from dsputil to avfloatdsp. This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.	12 years ago
Justin Ruggles	2ed40608e9	wma: do not keep private copies of some AVCodecContext fields channels, sample_rate, bit_rate, and block_align can be used directly from the AVCodecContext	12 years ago
Justin Ruggles	31b2262dca	wmaenc: use float planar sample format	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Martin Storsjö	710bd8a33e	wma: Lower the maximum number of channels to 2 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>	13 years ago
Diego Biurrun	8ca6e523a6	wma: Refactor common code to fix standalone compilation of WMA lossless decoder.	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
Martin Storsjö	e96b4a53df	vlc/rl: Add ff_ prefix to the nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	7181c4edee	cosmetics: Remove extra newlines at EOF	13 years ago
Alex Converse	d78bb1a4b2	wma: Clip WMA1 and WMA2 frame length to 11 bits. 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	13 years ago
Justin Ruggles	05d1e45d1f	wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits. 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.	13 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	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	fe2ff6d247	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> (cherry picked from commit `c73d99e672`)	14 years ago
