Hi,
Glad to hear that you discovered the problem.
The ffmpeg approach is ok. However, we recommend using libav instead of ffmpeg (the brand new fork of ffmpeg)
I need more details on the inputs and outputs. This is what I understand so fat:
source –YUV–> ffmpeg –mpegts/liveflv–> EMS –> multicast
If that is the case, that is the proper way to do it
Best regards,
Andrei
