Roland Scheidegger	9b9df1cdff	h264: new assembly version of get_cabac for x86_64 with PIC 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. get_cabac() gets about 40% faster, for an overall speedup of about 5%. Signed-off-by: Ronald S.

Roland Scheidegger	14e9ffc1e4	h264: use one table instead of several for cabac functions The reason is this is easier for PIC code (in particular on darwin...). Keep the old names as pointers (static in cabac_functions.h so gcc knows these are just immediate offsets) so the c code can nicely stay the same (alternatively could use offsets directly in the functions needing the tables). This should produce the same code as before with non-pic and better code (confirmed) with pic. The assembly uses the new table but still won't work for PIC case. Signed-off-by: Ronald S.

Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
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 It has been superseded by av_set_cpu_flag_mask() which, unlike this field, works everywhere.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
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.

Ronald S. Bultje	b089ca871a	dsputil: fix optimized emu_edge function on Win64. Recent register allocation changes (x86inc.asm update) changed the register order and thus opcodes for the inner loops. One of them became >128bytes, which confuses other parts of this function where it jumps to fixed-offset positions to extend the edge by fixed amounts. A simple register change fixes this.	13 years ago
