multi-track audio

Hello,

It’s possible to stream live video with two or more languages (english, german etc.)?

I found post about mp4 file streaming, but what about live stream?

Thanks.

This is possible with mpeg-ts and native rtp with multiple audio tracks. You need to turn on udp port sharing.

If mpeg-ts, use audiopid and videopid query params to select language. If native rtp, use multiple sdp files each pointing at different language.
