I got off-list advice and a link to a stack-exchange discussion on this matter: https://superuser.com/questions/792525/how-to-change-ffmpeg-threads-settings It turns out that my use is probably totally wrong since it limits the threads for the download function, which is not a heavy worker: "ffmpeg -threads 1 -user_agent \"Mozilla\" -i $VIDEOURL -vf scale=w=-4:h=360 -c:v libx264 -preset fast -crf 26 -c:a copy -t $CAPTURETIME $TARGETFILE" The proper position seems to be *after* the VIDEOURL instead. But I don't know where exactly it should be located. Maybe it does not matter? Like this instead: "ffmpeg -user_agent \"Mozilla\" -i $VIDEOURL -threads 1 -vf scale=w=-4:h=360 -c:v libx264 -preset fast -crf 26 -c:a copy -t $CAPTURETIME $TARGETFILE" These items are arguments to the script or global variables: $VIDEOURL (read from file) $CAPTURETIME (argument 1) $TARGETFILE (argument 2) -- Bo Berglund Developer in Sweden _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
