On the other hand, both libx264 and libx265 do scale quite well by smartly dividing the work over all available threads. Yes, you can really have up to 800% cpu usage on a 4x2 cpu (which is quite impressive), with both of them. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
