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.

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	e49d21306a	alacdec: implement the 2-pass prediction type. The reference encoder does not generate any streams using this, but the reference decoder can handle it, so we should as well.	13 years ago
