Hi, I have tried the latest SVN version (as of now) of ffmpeg2theora and libtheora. Seems to me that the MMX optimizations are not enabled: my binary is about 50% slower than the original binary ffmpeg2theora-0.16 found at http://www.v2v.cc/~j/ffmpeg2theora/ and my binary built with the old theora-mmx, and is slower as the pre-alpha6 theora. However the optimizations are enabled in the configure: ------------------------------------------------------------------------ libtheora 1.0alpha7-svn: Automatic configuration OK. General configuration: Encoding support: ........... yes Floating point support: ..... yes Assembly optimization: ...... 32 bit x86 Am I missing something or is it correct that current MMX enabled theora is much slower than the old theora-mmx?
