Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Jason Garrett-Glaser	ccba4f4c25	VP8: optimized mv prediction and decoding Merge find_near_mvs and mv bitstream decoding: don't do prediction steps until absolutely necessary. (cherry picked from commit `f3d09d44b7`)	14 years ago

Jason Garrett-Glaser	a1b0a3c8bd	VP8: idct_mb optimizations Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet. (cherry picked from commit `62457f9052`)	14 years ago

Ronald S. Bultje	ac3c04e4d6	Don't do edge emulation unless the edge pixels will be used in MC. 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 `44002d8323`)	14 years ago
