I also had a hard time getting to notice a difference with star/stop_timer, and it's clear why seeing how little difference this change truly makes. You can build the above tool with "make checkasm", and the executable will be in the tests/checkasm folder. The results tend to be less variable and it's better detecting small differences between functions. > And like, you both think it's a better way to do it, it's ok for me ! > > Thanks > > Martin > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel > _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
