Mans Rullgard	ac08f798bb	mp3dec: hack: fix decoding with safe bitstream reader The buffer splicing relies on the bitstream reader over-reading the end of the buffer as declared in init_get_bits(), although more data is actually present. Manually moving the bitstream boundary after init_get_bits() allows this to work as expected. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	583d3b7f97	fate: fix eatqi test The sample has an incomplete last frame. Decoding it is pointless. The garbage produced was changed by the bitstream reader now protecting against over-reads. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Shitiz Garg	e614fac2e6	adpcm: Check for channels to be a non-zero integer channels would be 0 sometimes and would cause floating point exception Fixes bugzilla #124 Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago

Ronald S. Bultje	8cfbbd928c	get_bits: introduce safe bitreading to prevent overreads. When turned on, H264/CAVLC gets ~15% (CVPCMNL1_SVA_C.264) slower for ultra-high-bitrate files, or ~2.5% (CVFI1_SVA_C.264) for lower-bitrate files. Other codecs are affected to a lesser extent because they are less optimized; e.g., VC-1 slows down by less than 1% (all on x86). The patch generated 3 extra instructions (cmp, cmovae and mov) per call to get_bits(). The performance penalty on ARM is within the error margin for most files, up to 4% in extreme cases such as CVPCMNL1_SVA_C.264. Based on work (for GCI) by Aneesh Dogra <lionaneesh@gmail.com>, and inspired by patch in Chromium by Chris Evans <cevans@chromium.org>.	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

Derek Buitenhuis	365e1ec26d	wavpack: Clip samples after shifting It doesn't make much sense to clip pre-shift, nor is it correct for proper decoding. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Ronald S. Bultje	0b4c323213	h264: don't drop B-frames after next keyframe on POC reset. The keyframe after a POC reset may not be the first to be returned to the user. Therefore, don't reset the expected next POC once we return a keyframe to the user, but once we know that the next frame in the return-queue is a keyframe.	13 years ago
