It is necessary to broadcast with an English-speaking lecturer, to a Russian-speaking and English-speaking audience, that is, in fact, there is only one video, and the user selects the audio stream.
Has anyone had such an experience?

Nothing complicated, most popular formats (mpegts, mp4, mp2) support multiple audio streams. The same ffmpeg (in my opinion, through the -map option) can add them. And then choose how to give to clients (http, rtsp, udp, dvb), pick up a player and go.
If necessary, write in a personal on Habré, we will arrange it directly for your case.
