Is it possible to get VLC to stream to a file a endlessly repeating mpeg file while at the same time dubbing an audio track over the top?

I have been doing:

vlc.exe -vvv video.mpg --input-repeat=5 --input-slave="sound.mp3" --sout="#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2}:duplicate{dst=std{access=file,mux=ts,dst=newvideo.mpg}}"

but unfortunately (and in reasonably slave-like fashion) that command sequence repeats the input-slave as well as the input.

Of course that everything is repeated, what would you want?

Yes I agree its exactly what the input-slave option should do - I didn't mean to imply any fault.

But is there an alternative set of parameters I could use to dub a single audio track over multiple repeats of a video?

Many thanks for your help.

Yes, with separate inputs, using VLM and bridging. Slave input is insufficient.

Many thanks - I will investigate that.

I have played around with VLM and it seems straightforward.

But for all my searching through the forums and documentation and cannot see how to combine two streams into one using the available syntax.

Be very grateful for some advice please.

Many thanks in advance
