2011-02-17Merge libavcore into libavutilReinhard Tartler
Done to keep ABI compatible. Otherwise this is just silly
2011-02-13VP8: ARM optimised decode_block_coeffs_internalMans Rullgard
Approximately 5% faster on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit a7878c9f73c12cfa685bd8af8f3afcca85f56a8b)
2011-02-11VP8: optimized mv prediction and decodingJason Garrett-Glaser
Merge find_near_mvs and mv bitstream decoding: don't do prediction steps until absolutely necessary. (cherry picked from commit f3d09d44b70492022964e2ead5f439bb7c96eaa2)
2011-02-09VP8: idct_mb optimizationsJason Garrett-Glaser
Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet. (cherry picked from commit 62457f9052ea15123688455aad866cb070634f13)

2011-01-26Don't do edge emulation unless the edge pixels will be used in MC.Ronald S. Bultje
Do not emulate larger edges than we will actually use for this round of MC. Decoding goes from avg+SE 29.972+/-0.023sec to 29.856+/-0.023, i.e. 0.12sec or ~0.4% faster. (cherry picked from commit 44002d8323023c35f51d523a7d305e45103ba7a1)

Originally committed as revision 24671 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-08-03VP8: much faster DC transform handlingJason Garrett-Glaser
A lot of the time the DC block is empty: don't do the WHT in this case. A lot of the rest of the time, there's only one coefficient: make a special DC-only transform for that case. When the block is empty, don't incorrectly mark luma DCT blocks as having DC coefficients. Originally committed as revision 24670 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-08-03VP8: move zeroing of luma DC block into the WHTJason Garrett-Glaser

Originally committed as revision 24469 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-24Decode DCT tokens by branching to a different code path for each branchDavid Conrad

2010-07-24VP8: always_inline some things to force gcc to do the right thingJason Garrett-Glaser
Mostly seems to help in the MC code, which gets a hundred cycles faster. Originally committed as revision 24463 to svn://svn.ffmpeg.org/ffmpeg/trunk
