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	c73d99e672	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>	14 years ago

Vitor Sessak	6776061b04	Add two more sizes to ff_sine_windows[] and also pad it with NULLs so that FF_ELEMS(ff_sine_windows[x]) == 1 << x. Fix issue 1384. Originally committed as revision 19862 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Sascha Sommer	4df8bdeef3	Simplify run level decoding: - remove unneeded vlc code < 0 check - reorder vlc code handling so that the unlikely escape decoding part comes last - move overflow check out of the decode loop - branchless sign conversion Originally committed as revision 19234 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Sascha Sommer	9970c61b4b	Introduce WMACoef typedef for decoded coefficients and change default type to float so that the run level decoding functionality can be shared with wmapro Originally committed as revision 19231 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Sascha Sommer	c0e9b2e84f	Move run level decode functionality to ff_wma_run_level_decode so that it can be reused for wmapro Originally committed as revision 19171 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
