Thanks a lot for the prompt answer.

I'll try this.

That's what I want to do: stream a list of files to one chanel, and another list to the second channel. I dind't make me clear, sorry about that. Indeed, I did a little test based on testMPEG1or2VideoStreamer with ByteStreamMultiFileSource and 1 sink and works ok, thanks.

So it would be for 2 sinks:

But how do I get to start again when the multifile source has ended? Do I have to reopen the source and call startPlaying() similar to what testMPEG1or2VideoStreamer does or there is something like a "loop" parameter?

Thanks again
