How can I add meta-information to the mp3 stream I'm streaming, using UDP Multicast ?

I'm not sure that it'll work in a ts stream but you could try using --meta-author, --meta-title, --meta-description ...

I already try that and it doesn't work. It is possible using another mux for my stream ? Or it is better to add the information previously in the mp3 stream (when I create it) ?

Thanks

You can add meta information to asf stream (using some special asf meta command line parameters).
It might be possible for other muxes like mp4.

I've never really tried using those features so I really can't help more. You might want to come on #videolan on irc.freenode.net to get better help

Still for mp3 stream, I would like to know if there is performance difference between ts mux and raw mux ?

Thanks

ts adds some overhead. I'm not sure if raw mp3 streaming is reliable (while ts is meant to be streamed).
