Mans Rullgard	95510be8c3	avcodec: remove AVCodecContext.dsp_mask This removes all references to AVCodecContext.dsp_mask and marks it for eviction at the next version bump. It has been superseded by av_set_cpu_flag_mask() which, unlike this field, works everywhere. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Michael Niedermayer	9849515214	Revert "h264: assembly version of get_cabac for x86_64 with PIC (v4)" This broke compilation on darwin, revert until a better solution is found. This reverts commit `a812b599b5`.	13 years ago
Jan Ekström	b5c3f0b994	utvideo: general cosmetics General cosmetics, such as keeping lines under 80 characters, fixing a couple of typos (predition -> prediction) and a general style fix that was pointed out by Derek when I was having my sliced multithreading patch in review by him.

Roland Scheidegger	a812b599b5	h264: assembly version of get_cabac for x86_64 with PIC (v4) This adds a hand-optimized assembly version for get_cabac much like the existing one, but it works if the table offsets are RIP-relative. Compared to the non-RIP-relative version this adds 2 lea instructions and it needs one extra register. There is a surprisingly large performance improvement over the c version (more so than the generated assembly seems to suggest) just in get_cabac, I measured roughly 40% faster for get_cabac on a K8. However, overall the difference is not that big, I measured roughly 5% on a test clip on a K8 and a Core2. Hopefully it still compiles on x86 32bit... v2: incorporated feedback from Loren Merritt to avoid rip-relative movs for every table, and got rid of unnecessary @GOTPCREL. v3: apply similar fixes to the the decode_significance functions, and use same macro arguments for non-pic case. v4: prettify inline asm arguments, add a non-fast-cmov version (as I expect the c code to be faster otherwise since both cmov and sbb suck hard on a Prescott, even can't construct the mask with a 64bit shift as that's just as terrible - it's quite difficult to find usable instructions on that chip...). This is tested to work but not on a P4, in theory it _should_ be fast there. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	903ccf71b7	error_concealment: Check that the reference is not NULL In normal picture decoding this does not need to be checked but as error concealment is run in the case of errors the availability of references is less certain.
