Can it be quicker and less resource<br>
hungry by altering the following command?<br>
<br>
:~$ /usr/local/bin/ffmpeg -i /link/to/music.mp3<br>
-i /link/to/video.mp4 -vcodec libx264 -crf 23<br>
-vf subtitles=/link/to/subtitles.srt -strict -2<br>
/link/to/muxed.mp4<br>

This is missing console output but at least<br>
-preset ultrafast (and friends) come to<br>
mind.

<div>This command will (if I understand correctly)
transcode your audio. Using "-c:a copy" will copy the
audio.mp3 into the muxed.mp4 container. Same thing with
"-c:v copy" as the video.mp4 is (obviously) already in
an MP4 container, it should be a trivial matter to mux
the two streams into a single MP4.<br>

Sorry, what do you mean by missing console output? This
command does output to the shell.<br>

<div>It would help us even more if you could provide what
your console outputs when the command runs.<br>
