<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>

<div>Vijay, Can you send me the input files so I can help
come up with a fix? I am away from my home computer where
I have a variety of mp4s and mp3s to test with. To me,
this SHOULDN'T fail, so I am curious to see this myself.<br>

Hey Steve,<br>
<br>
I am wondering how the media can help solve a command format.<br></div></blockquote><div><br></div><div>It was a suggestion, because I would then be able to use the exact files you are tying to use without having to guess at codecs that were used to encode them beforehand, test 5-6 other things and then come back and tell you what worked best for me, and give you the command that would work for you. I've noticed there's about a significant delay between us and thought that this would help speed things up.</div>
