I'm referring more to the fact that if I output to two outputs, from the same ffmpeg instance, in essence, this: ffmpeg -i input output1 output2 takes twice as long as running these two in parallel: ffmpeg -i input output1 ffmpeg -i input output2 It appears to me that the encoders are working in serial (at least in this instance, which is libx264 -preset ultrafast). In the first example it uses around 250% cpu, in the second, it uses around 500% cpu. Would be nice to be able to have the first use 500% cpu, if that makes sense. I assume it's just a feature request. Cheers! _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
