[FFmpeg-user] FFserver, switching, without interrupting, between multiple incoming sources for one stream outgoing rtsp

[Meta Coma]

Hello!

Guys, please help me with following RTSP streaming scheme:

my workflow:
  1. by default, stream is from Xvfb0 source to RTSP server
  2. after some time, I send, through zmq (zmqsend), some command sequence
to switch the source from Xvfb0 to Xvfb1 without RTSP stream interrupting

My question:
  Is it a possibility with ffmpeg + ffserver? If it's possible, which
commands sequence I'll send to ffserver?

Thanks!
