Justin Ruggles	81c9e2e6d0	alac: split element parsing into a separate function This will make multi-channel implementation simpler. Based partially on a patch by Andrew D'Addesio <modchipv12@gmail.com>.	13 years ago
Justin Ruggles	cd632619d9	alac: support a read sample size of up to 32 Use get_bits_long() in decode_scalar(). Use unsigned int for decoded value.	13 years ago
Justin Ruggles	73dc0db486	alac: output in planar sample format Avoids unneeded interleaving and allows for reusing the AVFrame output buffer as the internal buffer for 24-bit and 32-bit sample size.	13 years ago

Justin Ruggles	4bcd637dcb	alac: use sizeof() instead of hardcoded data sizes	13 years ago
Justin Ruggles	91620a04f1	alac: make block_size signed It does not need to be unsigned.	13 years ago
Justin Ruggles	2fc24b3273	alac: remove a duplicate local variable	13 years ago
Justin Ruggles	5177413d20	alac: conditionally set sign_modifier to 1 It is already unconditionally set to 0 prior to this, so we can modify it only when needed.	13 years ago
Justin Ruggles	7e6593e977	alac: eliminate 2 unneeded local variables in bastardized_rice_decompress() x_modified is just unnecessary, and final_val can be removed by simplifying the unsigned-to-signed conversion.	13 years ago
Justin Ruggles	6fd8a28b59	alac: adjust conditions for updating entropy decoder history avoids some unnecessary arithmetic in certain situations	13 years ago
Justin Ruggles	a06fdadd97	alac: cosmetics: reindent after last commit	13 years ago
Justin Ruggles	d9837434a9	alac: limit the rice param before passing to decode_scalar() reduces the number of parameters to decode_scalar() and slightly simplifies the code	13 years ago
Justin Ruggles	6e91f62256	alac: reduce the number of parameters to bastardized_rice_decompress() Use the ALACContext fields directly instead.	13 years ago

Justin Ruggles	2ac1737583	alac: clean up and update comments leftover from reverse-engineering	13 years ago
Mans Rullgard	bf1cf4d5a5	flacdec: reverse lpc coeff order, simplify filter Reversing the lpc coefficient order simplifies indexing in the filter. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	9f97af2688	x86: dsputil: drop some unused CPU flag debug code	13 years ago
Mans Rullgard	ffdd93a25e	ppc: fix build with altivec disabled Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
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
Mans Rullgard	ab9f987661	build: add CONFIG_VP3DSP, reduce repetition in OBJS lists 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
Kostya Shishkov	3c6c19184c	tscc2: fix typo in DCT	13 years ago
Michael Bradshaw	453c02f971	libopenjpeg: introduce encoding support Based on FFmpeg version from commit `713a7854e0` Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Michael Bradshaw	b43a7bb4f9	libopenjpeg: rename decoder source file. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Kostya Shishkov	0b40153d20	tscc2: DCT output should not be clipped This fixes decoding some TSCC2 files with large quantisers.	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. Also, values >20000 will have no effect and 20000 will be used anyway. Signed-off-by: Mohammad Alsaleh <msal@tormail.org> Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mashiat Sarker Shakkhar	082829520e	vc1dec: Do not use random pred_flag if motion vector data is skipped This fixes SA10143.vc1 from test-suite. Also partially fixes MC-VC1.ts from videolan streams archive. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	25f056e6d4	vp8: Enclose pthread function calls in ifdefs This fixes building with threads disabled. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Ronald S. Bultje	c44091a9f7	snow: refactor code to work around a compiler bug in MSVC. This fixes the compiler error "cannot convert from 'BlockNode' to 'int16_t'".	13 years ago
Martin Storsjö	a794600c00	vp8: Include the thread headers before using the pthread types This was unnoticed on linux, since stdlib.h apparently includes files declaring the pthread_mutex_t and pthread_cond_t types. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
