Jason Garrett-Glaser 9a0dda8b3a H.264: disable 2tap qpel with CODEC_FLAG2_FAST and >8-bit 
2tap qpel isn't implemented yet for high bit depth, so it just breaks decoding.

Jason Garrett-Glaser 7b442ad918 H.264: fix CODEC_FLAG_GRAY 
It was broken in 4:4:4, and still did chroma deblocking for no reason in 4:2:0.
 2011-06-13 21:16:33 -07:00
Jason Garrett-Glaser c90b94424c 4:4:4 H.264 decoding support 
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
 2011-06-13 21:16:30 -07:00
Jason Garrett-Glaser 504811baea Roll back 4:4:4 H.264 for now 
Needs some ARM/PPC asm modifications.

Also delete some unused deblock asm macros.

Jason Garrett-Glaser 9f3d6ca4f1 Port x86 10-bit H.264 deblock asm from x264 2011-05-10 20:02:15 -07:00
Jason Garrett-Glaser 8ad77b65b5 Update x86 H.264 deblock asm 
Includes AVX versions from x264.
 2011-05-10 20:01:58 -07:00
Jason Garrett-GlaserandRonald S. Bultje 15919ee48f bswap: use native types for av_bwap16(). 
This prevents a call to bytestream_get_be16() using a movzwl both before
and after the ror instruction, which is obviously inefficient. Arm uses
the same trick also.

Sintel decoding goes from (avg+SD) 9.856 +/- 0.003 to 9.797 +/- 0.003 sec.

Jason Garrett-Glaser 81a131312d VP8: fix other function declaration 
Was missed in 3efbe137.
 2011-03-12 15:36:15 -08:00
Jason Garrett-Glaser 1eeca88691 VP8: optimize VP8Context struct ordering 
Shaves at least 3KB off code size on x86, should improve cache utilization.
This would probably be useful to do for other decoders/encoders as well.
 2011-03-12 03:43:42 -08:00
Jason Garrett-Glaser 3efbe13739 VP8: fix function declaration 2011-03-12 03:41:39 -08:00
Jason Garrett-Glaser b1d2f812c9 VP8: token probs doesn't need padding 
prob[0] is the only prob array ever accessed, so prob[1] can serve as padding
for prob[0].
 2011-03-12 03:41:36 -08:00
Jason Garrett-Glaser 628b48db85 VP8: use a goto to break out of two loops 
A break statement was supposed to break out of two loops, but only broke out of one.
Didn't affect output, just could have been marginally slower.
 2011-03-12 03:41:33 -08:00
Jason Garrett-Glaser 902685b8ab VP3: fix decoding of videos with stride > 2048 
Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't
use an MPEG-like quantizer scale.
 2011-02-18 14:40:57 -08:00
Jason Garrett-Glaser 891b1f15a7 VP8: init one less near_mv 
This one didn't actually need to be initialized.
 2011-02-17 15:25:28 -08:00
Jason Garrett-Glaser eb3755a5aa Force inlining of avutil common routines 
On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files.  This is generally bad, as most of these
functions are smaller inlined than not.

Jason Garrett-Glaser f3d09d44b7 VP8: optimized mv prediction and decoding 
Merge find_near_mvs and mv bitstream decoding: don't do prediction steps
until absolutely necessary.
 2011-02-10 16:18:16 -08:00
Jason Garrett-Glaser c7ac200d15 Update qmin/qmax values for libx264 presets 
Also allow qmin/qmax to go up to 69 (the current max value for libx264).  This
will have to increase when we add 9/10-bit support.
 2011-02-08 15:59:30 -08:00
Jason Garrett-Glaser f7f8120fb9 Fix broken vbv_buffer_init handling in libx264.c 
Due to being pants-on-head retarded, libavcodec defaults this to zero, which
results in broken output.  This didn't affect ffmpeg.c, which sets it itself,
but caused problems for other calling apps using VBV.
 2011-02-08 15:59:27 -08:00
Jason Garrett-Glaser 62457f9052 VP8: idct_mb optimizations 
Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet.

Jason Garrett-Glaser 64233e702a VP8: merge chroma MC calls 
Adds some duplicated code, but avoids duplicate edge checks and similar.
~0.5% faster overall on Parkjoy test sample.

Jason Garrett-Glaser 73be29b0c4 Slightly simplify VP8 inter_predict 
Merge an if and a switch.
