Its not about low-end, its about 15+ years old hardware. At some point you just have to replace this stuff. For $100 you can buy a system at least 10 times as fast then those. Heck even a RPi might rival those for $20 or so. If you want to convince developers to fix the MMX situation properly, which would cost a lot of time to do, then the best course is to look forward, which the SSE2 option imho is doing. All other options are just band-aids. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
