Jason Garrett-Glaser 10bf2eebbe VP8: simplify token_prob handling 
~1.5% faster decode_block_coeffs

Jason Garrett-Glaser e25dee602f VP8: Much faster SSE2 MC 
5-10% faster or more on Phenom, Athlon 64, and some others.
Helps some on pre-SSSE3 Intel chips as well, but not as much.

Jason Garrett-Glaser 8a467b2d44 VP8: 30% faster idct_mb 
Take shortcuts based on statistically common situations.
Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT
blocks are common.
TODO: tie this more directly into the MB mode, since the DC-level transform is
only used for non-splitmv blocks?

Jason Garrett-Glaser ef38842f0b VP8: smarter prefetching 
Don't prefetch reference frames that were used less than 1/32th of the time so
far in the frame.
This helps speed up to ~2% on videos that, in many frames, make near-zero
(but not entirely zero) use of golden and/or alt-refs.
This is a very common property of videos encoded by libvpx.

Jason Garrett-Glaser c4211046d2 Smarter VP8 prefetching 
Prefetch all refs (including altref), but only if they've been used so far this
frame.
~2.5% faster overall.

TODO: Do something even smarter, like using how often each ref has been used
so far, so that a couple blocks of a rarely-used ref don't force us to prefetch
it.

 2010-07-22 11:55:55 +00:00
Jason Garrett-Glaser c55e0d34ba Convert VP8 macroblock structures to a ring buffer. 
Uses a slightly nonintuitive ring buffer size of (width+height*2) to simplify
addressing logic.
Also split out the segmentation map to a separate structure, necessary to
implement the ring buffer.

Jason Garrett-Glaser 968570d65f Calculate deblock strength per-MB instead of per-row 
Gives better cache locality, since the VP8Macroblock structs are still in cache.
Inspired by the way x264 does it.

Jason Garrett-Glaser 4148855ee4 Eliminate another redundant instruction in vp56/8 arithcoder 
Necessary because of this GCC bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474
To do this, convert some, but not all (!) of the variables in VP56RangeCoder
into local variables.
If we convert c->high into a local variable, gcc gets the stupids and refuses
to use a conditional move for the unpredictable main branch.

TODO: dispense with this bullshit and write an asm version.

 2010-06-30 23:59:27 +00:00
Jason Garrett-Glaser 36d6b545a1 CMOV-ify vp56 arithcoder 
This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option
than a completely unpredictable branch.
Hopefully this carries over to newer versions and other CPUs with conditionals.
~5 cycles saved per call on a Core i7.

Jason Garrett-Glaser fe022ce2f8 Fix libx264.c to not drop SEI userdata from x264 encoder. 
Most muxers in ffmpeg ignore the SEI if it is placed in extradata, so instead
it has to be catted to the front of the first video frame.

Jason Garrett-Glaser 351653a51e VC-1/WMV: Remove redundant ff_init_block_index() calls. 
These are only supposed to be called once per row, not once per macroblock.
~1.5% faster according to oprofile.

Jason Garrett-Glaser 010f98f96a VC-1/WMV3 decoding: don't clear blocks unless they're actually used. 
~8% faster VC-1 decoding.
Possible future optimization: clear blocks after use instead of before, and for
DC-only blocks, only clear the DC coefficient.

Jason Garrett-Glaser 4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. 
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

which is documented to be MPEG-1 video.  Adding fourcc to isom.c.
