Michael Niedermayer	9522a752bf	xsubenc: only 1 rectangle is supported so dont allow 0 as it would crash. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago

Michael Niedermayer	3acc44b739	bitstream reader: remove unneeded variable initilization. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Ronald S. Bultje	7d2e03afc8	vc1: make overlap filter for I-frames bit-exact.	14 years ago
Ronald S. Bultje	5c9f147e05	vc1dec: use s->start/end_mb_y instead of passing them as function args.	14 years ago
Ronald S. Bultje	18b6a69ce9	Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." This reverts commit `f8bed30d8b`. The reason for this is that the overlap filter, which runs after IDCT, should run on unclamped values, and thus IDCT and put_pixels() cannot be merged if we want to attempt to be bitexact.	14 years ago
Alex Converse	1a5e4fd8c5	Replace strncpy() with av_strlcpy().	14 years ago
Alex Converse	aab6374bbe	indeo3: Eliminate use of long.	15 years ago

ami_stuff	c402ce418a	Remove lowres support from wmv2 decoder lowres option crashes with wmv2 files which I have for test, so I think it's better to remove the support to the time when lowres will be really supported by this codec Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	15 years ago
Carl Eugen Hoyos	7d70d1937a	Support decoding of 24 bit True Audio samples- Many samples will fail because "Output buffer size is too small."	14 years ago
Carl Eugen Hoyos	4cf2e30f05	Support decoding of 8 bit True Audio samples- Many samples will fail because "Output buffer size is too small."	14 years ago
Carl Eugen Hoyos	fba418e670	Do not assume AV_SAMPLE_FMT_S16 as tta sample format.	14 years ago
Alexandre Colucci	3b4621acbb	Fix init_get_bits length argument for init_get_bits. Do not use rlelen for buffer size in init_get_bits, it is only the size of the data for the first field. Since it is not reliable, just use the size of the whole buffer. Additional comments add removal of unused rlelen variable by Reimar Döffinger.	14 years ago
Reimar Döffinger	cf16104ad1	Change guess_palette so its output matches the most common palette. This means it uses full brightness range and brightness increasing instead of decreasing with index of non-opaque color. Based on patch by Alexandre Colucci [alexandre elgato com]	14 years ago

Kostya Shishkov	b178cd76b2	dpx: Do not use DPX encoder for decoding. 10l to the one who hasn't checked this.	14 years ago
Michael Niedermayer	007d352c1c	dct-test: Support testing bits>8 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Diego Biurrun	ad1862d64a	ALPHA: Replace sized int_fast integer types with plain int/unsigned. int/unsigned is the natural memory access type for CPUs, using sized types for temporary variables, counters and similar just increases code size and can possibly cause a slowdown.	14 years ago

Peter Ross	406629150c	DPX decoder: read sample aspect ratio Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	15 years ago
Reimar Döffinger	3777ea13fb	DPX decoder: add buffer size checks.	15 years ago
Justin Ruggles	63b1866ae1	ac3enc: clip large coefficient values and negative exponents rather than using av_assert2().	15 years ago
Justin Ruggles	177fed4e9b	ac3enc: do not store a bandwidth code for each channel. Although AC-3 allows it, it's not very useful. The encoder uses the same code for all full-bandwidth channels.	15 years ago
Justin Ruggles	a1d0f511fc	ac3enc: remove bandwidth reduction as fallback for bit allocation failure. It was only needed at low bitrates, which now already use a low bandwidth, so the bandwidth reduction is no longer needed.	15 years ago
Justin Ruggles	ba6bce5140	ac3enc: merge compute_exp_strategy_ch() into compute_exp_strategy()	15 years ago
Justin Ruggles	4142487d1c	ac3enc: return error if frame+exponent bits are too large instead of using av_assert2(). This can occur in some very rare cases with low bitrates.	15 years ago
Justin Ruggles	987fe2dc55	ac3enc: differentiate between current block and reference block in bit_alloc()	15 years ago
Justin Ruggles	6b2636bba6	ac3enc: simplify exponent_init() by calculating exponent_group_tab[] based on exponent group sizes.	15 years ago
Justin Ruggles	e0b33d479c	ac3enc: simplify stereo rematrixing decision options	15 years ago
Reimar Döffinger	636ee66f1c	Fix data_size handling for AC3 and dca decoders. They use now code identical to the AAC decoder. The AC3 decoder previously did not check the data_size and the dca decoder checked against and set wrong values for float.	14 years ago
Stefano Sabatini	77e9dee8ae	lavc: add a sample_aspect_ratio field to AVFrame The sample aspect ratio is a per-frame property, so it makes sense to define it in AVFrame rather than in the codec/stream context. Simplify application-level sample aspect ratio information extraction, and allow further simplifications.	14 years ago
Stefano Sabatini	1ba5727242	lavc: add a pkt_pos field to AVFrame This is similar to what was done with pkt_pts. This simplifies the operation of extracting the pos information from the AVPacket, and allows further simplifications.	14 years ago
