Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago
Paul B Mahol	5eda82aac9	frwu: check if allocation was successful Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mashiat Sarker Shakkhar	d51d6ae9c4	vc1dec.c: Don't use uninitialized values of dmv_[x, y] MVDATA may or may not be transmitted. If it is not, both dmv_x and dmv_y is to be assumed zero. This may not trigger wrong picture in all systems, but it's a bug nevertheless. Fixes SA10116.vc1 on my 64-bit Windows 7. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Alex Converse	b57d262412	mjpegbdec: Fix overflow in SOS. Based in part by a fix from Michael Niedermayer <michaelni@gmx.at> Fixes CVE-2011-3947 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	13 years ago

Alex Converse	90c0c83e14	smacker: remove dead store	13 years ago
Alex Converse	dac56d9ce0	qdm2: Check data block size for bytes to bits overflow. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Hendrik Leppkes	feaa40020b	vc1: always read the bfraction element for interlaced fields Previously, it would not be read if refdist_flag was not set, however according to the spec and the reference decoder, it should always be read. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	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
Janne Grunau	c3e10ae412	rv20: prevent calling ff_h263_decode_mba() with unset height/width Prevents a crash of VLC during playback of a invalid matroska file, found by John Villamil <johnv@matasano.com>. CC: libav-stable@libav.org	13 years ago
Diego Biurrun	07a873a277	build: Automatically include architecture-specific library Makefile snippets.	13 years ago
Janne Grunau	366ac22ea5	indeo5: prevent null pointer dereference on broken files Found by John Villamil <johnv@matasano.com>	13 years ago
Diego Biurrun	33ad8c3cab	cosmetics: Remove some unnecessary block braces.	13 years ago
Ronald S. Bultje	c3af52fa8b	dsputil: use vertical component for drawing bottom edge. Current code only writes 8 pixels of vertical edge for YUV422, which causes MC artifacts when subsequent frames use data from that edge.	13 years ago
Alex Converse	efe68076da	aacenc: Fix identification padding when the bitstream is already aligned.	13 years ago
Michael Niedermayer	cdfe94c5ab	aacenc: Write correct length for long identification strings. When the length is the escape value (15), the new length is calculated by 15 + get_bits(8) - 1. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Justin Ruggles	02e7dbf5ad	adpcm_ima_ws: fix stereo decoding Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for VQA version 2.	13 years ago
Justin Ruggles	220506d23f	avcodec: add a new codec_id for CRYO APC IMA ADPCM. The stereo layout and extradata is significantly different from that in Westwood IMA ADPCM, so a separate codec_id is warranted.	13 years ago
Anton Khirnov	1381e9bc92	lavc: postpone the removal of AVCodecContext.request_channels. Although it has been deprecated for a long time, its intended replacement (request_channel_layout) is not actually used anywhere, so request_channels is currently the only way to access that functionality.	13 years ago
Anton Khirnov	af0292f33a	lavc: postpone removing old audio encoding and decoding API It has been deprecated only recently.	13 years ago

Nathan Caldwell	80d44277e6	aacenc: Move Q^3/4 calculation to it's own table This should be moved to tablegen at some point. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago

Janne Grunau	2473a45c85	threads: change the default for threads back to 1 Using threaded decoding by default breaks backward compatibility if AVHWAccel is used or if an appliction sets threadunsafe callbacks. Avconv and avplay still use -threads auto if not specified.	13 years ago
Janne Grunau	afb8b207d6	threads: update slice_count and slice_offset from user context They are used to signal the number of slices and offsets of each slice out of band to the decoder.	13 years ago

John Brooks	9b6aafba6c	mpegvideo: fix invalid memory access for small video dimensions When either video dimension is only one macroblock, subtractions based on v_edge_pos and the macroblock size may be negative. In that situation, an unsigned comparison isn't sufficent to test for MV overruns, because a limit of (unsigned)-1 will let any other value pass.
