Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Justin Ruggles	3f6aa85ed4	avcodec: attempt to clarify the CODEC_CAP_DELAY documentation	13 years ago
Justin Ruggles	07837e4158	avcodec: fix avcodec_encode_audio() documentation. the previous documentation indicated how many bytes are read from the input, not how many samples are read.	13 years ago
Justin Ruggles	cf1a259ad6	g722enc: validate AVCodecContext.trellis	13 years ago
Justin Ruggles	77c5b66cbe	g722enc: set frame_size, and also handle an odd number of input samples The fate reference is updated because the previous test skipped a sample in each encode() call due each input frame having an odd number of samples.	13 years ago
Justin Ruggles	34093ba081	g722enc: split encoding into separate functions for trellis vs. no trellis	13 years ago

Martin Storsjö	c5d907b6b0	libavcodec: Handle param change side data in avcodec_decode_video2, too Also call avcodec_set_dimensions on dimension param change packets. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	867f923df4	libavcodec: Move apply_param_change up above avcodec_decode_video2 This is in preparation to calling it from avcodec_decode_video2. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Janne Grunau	be540e0cb3	indeo3: check motion vectors for validity Fixes null pointer dereferences in fuzzed files found by Oana Stratulat. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Michael Niedermayer	b18a0cc781	indeo5: Fix null pointer dereference. Bug found by: Oana Stratulat Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago

Chris Evans	57cd6d7095	vorbis: Avoid some out-of-bounds reads Fixes Bug: #190 Chromium Bug: #100543 Related to CVE-2011-3893 Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Diego Biurrun	3aa3fc45fe	cabac: remove unused function renorm_cabac_decoder	13 years ago
Diego Biurrun	301fb92131	h264: Only use symbols from the SVQ3 decoder under proper conditionals. Fixes --disable-everything --enable-decoder=h264 --disable-optimizations.	13 years ago
Justin Ruggles	6e8bf6db48	add bytestream2_tell() and bytestream2_seek() functions	13 years ago
Janne Grunau	f907615f08	parsers: initialize MpegEncContext.slice_context_count to 1 The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly) a MpegEncContext in their private context. Since they do not call the common mpegvideo init function slice_context_count has explicitly set to 1. Prevents a null pointer dereference in the h264 parser and fixes bug 193.	13 years ago
Janne Grunau	696ace50ea	truemotion2: check size before GetBitContext initialisation Prevents null ptr derefence for negative sizes.	13 years ago
Janne Grunau	bb5b3940b0	adpcm: ADPCM Electronic Arts has always two channels	13 years ago
Aneesh Dogra	9b55b4bb3a	4xm: Prevent buffer overreads. 4xm decoder while decoding i2 frames can overread the buffer if proper checks are not made. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Janne Grunau	e268a352af	mjpegdec: parse RSTn to prevent skipping other data in mjpeg_decode_scan Check explicitly if enough bits are left to prevent an infinite loop when the bitstream buffer is not followed by zero-padding. Based on patches by Michael Niedermayer <michaelni@gmx.at>.	13 years ago
Janne Grunau	9b4767e478	vp3: fix streams with non-zero last coefficient Fixes a regression introduced in `8b94df0f20`.	13 years ago
Oana Stratulat	7f09791d28	Report an error if pitch_lag is zero in AMR-NB decoder. This fixes an infinite loop in the decoder on specially crafted files, and fixes bug 151. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	3fa646e859	Revert "4xm: Prevent buffer overreads." This reverts commit `295a7c0238`. The patch breaks decoding of regular files (e.g. fate-4xm-2).	13 years ago
Aneesh Dogra	295a7c0238	4xm: Prevent buffer overreads. 4xm decoder while decoding i2 frames can overread the buffer if proper checks are not made. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Aneesh Dogra	4b84f68223	4xm: pass the correct remaining buffer size to decode_i2_frame(). frame_size is the number of bytes left in the packet, so if we are passing buf-4 we can safely read frame_size+4 bytes. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Aneesh Dogra	893f137679	4xm: fix calculation of the next output line position in decode_i2_frame(). The current code doesn't work unless width is an exact multiple of 16. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	89d26797f5	ulti: convert to new bytestream API.	13 years ago
Diego Biurrun	00a1cdd264	Place some START_TIMER invocations in separate blocks. This fixes compilation failures related to START_TIMER/STOP_TIMER macros and -Werror=declaration-after-statement. START_TIMER declares variables and thus may not be placed after statements outside of a new block.	13 years ago
John Brooks	d209c27b09	vc1dec: fix invalid memory access for small video dimensions For small video dimensions, these calculations of the upper bound for pixel access may have a negative result. Using an unsigned comparison to bound a potentially negative value only works if the greater operand is non-negative. Fixed by doing edge emulation when the upper bound is probably negative, everywhere that this pattern appears. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
John Brooks	aacf6b3a2f	rv34: fix invalid memory access for small video dimensions For small video dimensions calculations of the upper bound for pixel access may result in negative value. Using an unsigned comparison works only if the greater operand is non-negative. This is fixed by doing edge emulation explicitly for such conditions. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Christophe GISQUET	98f24ecd6c	rv34: joint coefficient decoding and dequantization Perform dequantization while decoding coefficients instead of performing it on the entire coefficients buffer. Since quantized coefficients are very sparse, this usually causes a small speedup. Speedup of around 1% on Panda board compared to the removed here neon code. Global speedup is probably around 3%.

Ronald S. Bultje	400ba1d735	h264: return index in buffer on end-of-sequence. Fixes hangs if the last packet contains an end-of-sequence NAL unit, bug 158.	13 years ago
Diego Biurrun	54e68fb3b8	Merge some declarations and initializations. This fixes compilation failures related to START_TIMER/STOP_TIMER macros and -Werror=declaration-after-statement. START_TIMER declares variables and thus may not be placed after statements outside of a new block.	13 years ago

Justin Ruggles	6c117bd8e0	adxenc: remove unneeded loops avctx->frame_size is 32, so that is how many samples we process per call.	13 years ago
