Mans Rullgard	28f9ab7029	vp3: move idct and loop filter pointers to new vp3dsp context This moves all VP3-specific function pointers from dsputil to a new vp3dsp context. There is no reason to ever use the VP3 IDCT where an MPEG2 IDCT is expected or vice versa. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Kostya Shishkov	4cfb0d871d	tscc2: do not add/subtract 128 bias during DCT It turns out that the reference decoder subtracts 128 from DC during block decode but adds it back during reordering block with zigzag pattern. Transforming block with incorrect DC caused heavy visual artifacts for many quantisers.	13 years ago

Paul B Mahol	7543fd80e5	exr: check size of uncompressed buffer returned by uncompress() The actual size of uncompressed buffer returned by uncompress() may be smaller than expected, so abort decoding in such cases. Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Mohammad Alsaleh	c37c383e59	libfdk-aac: Check if cutoff value is valid Passing a cutoff value < sample_rate/256 will cause a crash.

Paul B Mahol	2c31ed3330	exr: make channel_offsets int instead of int8_t Prior to this change max number of channels for float data which was going to be correctly decoded was 32, which is rather small considering that exr allows multiple channel layers.

Philip Langdale	2c501ae82b	movtextdec: 3GPP TS 26.245 Timed Text Decoder. This change introduces a basic decoder for 3GPP Timed Text subtitles, also known as TX3G, Quicktime subtitles, or "movtext" in the existing code. This initial change doesn't attempt to parse styling information, and just reads the plain text of the subtitles. I intend to add support for styles eventually, but it's challenging due to a lack of existing players that support them. Signed-off-by: Philip Langdale <philipl@overt.org>	13 years ago
Daniel Kang	951455c1c1	vp8: implement sliced threading Testing gives 25-30% gain on HD clips with two threads and up to 50% gain with eight threads. Sliced threading uses more memory than single or frame threading. Frame threading and single threading keep the previous memory layout. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
