This is my data flow:

Janus -> RTP_forward -> FFMPEG -> Nginx RTMP -> HLS/M3U

================== =============================

Server 1 Server 2

When i run debug at FFMPEG there is warning:
...

[NULL @ 0x220aa40] RTP: missed 24 packets 79.5kbits/s

[NULL @ 0x220aa40] RTP: missed 36 packets 79.5kbits/s

[NULL @ 0x220aa40] RTP: missed 20 packets 79.3kbits/s

....

Is this the Janus or FFMpeg problem?

Is this the Janus or FFMpeg problem?

Maybe network between server 1 and server 2 ?

Thank you Steve and Jo Jo.

CentOS much more friendly (less missed packet) than Ubuntu.
