ffmpeg multithreading #24

Closed andrasfuchs closed 11 years ago

andrasfuchs commented 11 years ago

ffmpeg has the option to use multiple cores, if we pass the -threads x parameter to it.

I've tested it with the "-threads 8" and it looked like it had an impact on the performance of the codec.

I think others would benefit from this option as well.

I've just stumbled upon this thread: http://stackoverflow.com/questions/7379980/thread-count-option-in-ffmpeg-for-fastest-conversion-to-h264

According to this, the -threads parameter is useless in most cases, since the default setting is probably slightly more efficient. (one-thread-per-core)
