1) some sport live event is restreamed through Wowza
2) we need a commenter to sit somewhere and comment that live event with voice.
3) so client should receive the stream where audio = audio1(of live event) + audio2(commenter voice)
Is this possible with Wowza (transcoder) ?
If not, can you suggest another software to do this?
Client-side audio mixing solution is bad because for example it is impossible for iOS player.
So now we're searching for any possible way to mix the streams somewhere on server side.
