Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Michael Smith	0881cbf314	proresdec: support mixed interlaced/non-interlaced content Set interlaced to false if we don't have an interlaced frame Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Diego Biurrun	8f4c414df6	Improve wording and spelling of av_log_missing_feature messages.	12 years ago

Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Kostya Shishkov	12b812d2e5	prores: store and retrieve extended colourspace information Based on the patch by Phil Barrett.	13 years ago
Kostya Shishkov	235d693286	prores: handle 444 chroma in right order ProRes codes chroma blocks in 444 mode in different order than luma blocks, so make both decoder and encoder read/write chroma blocks in right order. Reported by Phil Barrett	13 years ago
Christophe GISQUET	b5696ff2b8	prores: use natural integer type for the codebook index The operations that use it require it to be promoted to a larger (natural) type and thus perform sign extension on it. While an optimal compiler may account for this, gcc 4.6 (for x86 Windows) fails. Using the natural integer type provides a 2% speedup for Win64 and 1% for Win32.

Kostya Shishkov	8835c2c829	prores: move data shared between decoder and encoder to common file	13 years ago
Kostya Shishkov	3ec623c22f	prores: fix multithreaded decoding case when slice quantisers are not the same Since quantisation matrices are stored in context, decoding slices with different quantisers in parallel leads to unpredictable content of aforementioned matrices and wrong output picture thereof.	13 years ago
Ronald S. Bultje	73e15e8e6b	prores: specify array size outside DECLARE_ALIGNED brackets.	13 years ago
Mans Rullgard	a1e98f198e	get_bits: remove A32 variant The A32 bitstream reader variant is only used on ARMv5 and for Prores due to the larger bit cache this decoder requires. In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only statistically significant difference between ALT and A32 is a 4% advantage for ALT in FLAC decoding. There is thus no (longer) any reason to keep the A32 reader from this point of view. This patch adds an option to the ALT reader increasing the bit cache to 32 bits as required by the Prores decoder. Benchmarking shows no significant change in speed on Intel i7. Again, the A32 reader fails to justify its existence. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	179ae53fed	proresdec: fix decode_slice() prototype Make the function prototype match the argument of AVCodecCntext.execute() and remove the cast hiding this mismatch. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	da9cea77e3	Fix a bunch of common typos.	13 years ago
Mans Rullgard	91038cdbd1	prores: get correct size for coded V plane if alpha is present The size check must be updated to take into account both manners in which v_data_size might be set. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	cd14e297e6	prores: do not set pixel format on codec init The pixel format is not known until the frame header is parsed. Guessing it here only causes trouble for the caller if the guess turns out to be wrong (and actually causes very wrong output by avconv/avplay).

Janne Grunau	19ec283f49	prores: add missing feature warning for alpha	13 years ago
Ronald S. Bultje	91f4732913	prores: implement multithreading. 60% speedup (overall decoding time) at 2 threads, and another 60% speedup at 4 threads.	13 years ago
Ronald S. Bultje	e3f530feca	prores: idct sse2/sse4 optimizations. ~3.0-3.5x as fast as original C version, 1.6x as fast overall.	13 years ago
Ronald S. Bultje	92fb52d906	prores: extract idct into its own dspcontext and merge with put_pixels.	13 years ago
Alex Converse	fcbe421cee	prores: Handle 0 or fewer bits left show_bits() is undefined when the number of bits is less than or equal to zero.	13 years ago
