Jason Garrett-Glaser 73b02e2460 SSE version of clear_blocks 
Originally committed as revision 19206 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-06-16 17:33:57 +00:00
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).

Jason Garrett-Glaser 67fe508916 Analysis of logs show that there are in fact some files with m1v1 too (not just m2v2), 
which is documented to be MPEG-1 video.  Adding fourcc to isom.c.

Jason Garrett-Glaser 761cb87173 Add "0x11005354" as a fourcc for MOV audio; fixes audio detection in a problematic MOV file. 
The audio is actually adpcm_ima_wav.

Jason Garrett-Glaser a22eff36f9 Port x264 deblocking code to libavcodec. 
This includes SSE2 luma deblocking code and both MMXEXT and SSE2 luma
intra deblocking code for H.264 decoding. This assembly is available
under --enable-gpl and speeds decoding of Cathedral by 7%.

Jason Garrett-Glaser a5d2413345 x264 has removed the b-rdo and bime options, and instead integrated 
them into the subme number to attempt to reduce the number of
unnecessary options.  subme now scales up to 9.
