We’re using shoutcast for sending audio streams seperatelly from the server to our clients and we want to integrate all audio streams (2-5 languages…) into the wowza player. Is there any news about how to solve this?, besides what was already posted in this thread?

i am talking about multiple audio streams for a livestream, is your link also suitable for this? 🙂

Why is “a stream with multiple channels” not what i am asking for?

But that is surely somehow possible, no?

I am trying to add additional audio tracks to the video like many languages:

ffmpeg -i “F:\Video.mp4″ -i “F:\Audio.MP3″ -vcodec copy -acodec copy -shortest -f flv -map 0:0 -map 1:0 rtmp://IP/input.stream

But at the output I get the video without original audio with only mp3 audio, I cannot choose the audio track (original or additional mp3). Where could be the problem?
