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	1193d3fedd	alac: use get_sbits() to read LPC coefficients instead of casting	13 years ago
Justin Ruggles	7a50ec6799	alac: move the current samples per frame to the ALACContext This will simplify the multi-channel implementation.	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

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
