Stefano Sabatini	7030501383	libopenjpeg: set internal frame defaults Fix ffmpeg decoding, which was broken after the recent changes in vsrc_buffer.	14 years ago
Reimar Döffinger	6fd00e9dd9	aacdec: add decode_channel_map overread check All decode_channel_map calls together can easily read more data than the amount of padding available. Thus below patch adds an input length check before reading them. Fixes some invalid reads with sample from http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1138	14 years ago
Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago
Stefano Sabatini	18ded93ab3	lavc: add format field to AVFrame The format is a per-frame property, having it in AVFrame simplify the operation of extraction of that information, since avoids the need to access the codec/stream context.	14 years ago
Stefano Sabatini	22333a6b19	lavc: add width and height fields to AVFrame width and height are per-frame properties, setting these values in AVFrame simplify the operation of extraction of that information, since avoids the need to check the codec/stream context.	14 years ago
Reimar Döffinger	f44967b1b5	Use av_fast_malloc instead of av_fast_realloc. Avoids a memleak, is less code and might be faster.	14 years ago
Reimar Döffinger	20e5d64a1a	msvideo1enc: minor cosmetic cleanup, use FFALIGN, avoid calculating value twice and add a missing "const".	14 years ago

JULIAN GARDNER	423986fc09	Allow encodiing empty subtitles.	14 years ago
Alex Converse	869303bebd	wmavoice: Use proper size in memeset(). sizeof(array_functrion_argument) gives the size of the pointer type not the size of the array to which it points.	14 years ago

JULIAN GARDNER	e822c237b3	dvbsubdec: Split delete_state()	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

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>	14 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

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
