Replacing the audio stream without re-encoding the video

[fafaman]

Hi,

I would like to know if I can use VLC to change the audio track of a video without having to re-encode (and potentially lose quality in) video stream. as VLC is very good at differentiating container from codec, I imagine this should be possible, but all examples I found use the #transocde module... Does using transcode encoding to be the same as the original video format will 'bypass' the transcoder allowing to keep the original quality? Should I use an other method?

For info, my original video has .m4v extention.

Thanks for your help,
Fa.

Don't specify any vcodec in your transcode line.

Hi. Not wanted to create a new subject. I have a question. How do I replace the original audio track with a new one without saving the old one?

No answer, but nothing). I found a wonderful solution called "Avidemux". But I would love to return to VLC as soon as the opportunity arises. I do not like when a lot of programs)
