[FFmpeg-user] One input, two ffmpeg instances one output. Is that possible?

Good morning guys.

I have following setup:

Udp multicast (transport stream) -> ffmpeg encoder generating hls fragments
+ nginx serving them as static files -> cdn.

I wanted to provide high availability at encoder layer, but without messing
with cdn and player.

I can add to cdn more http backends, but the question is:

Is it possible to generate binary equal fragments on two different encoders
from the same udp source?

I've tried with copyts, scenecut, etc and I achieved fragments with similar
PTS inside, but not identical.

Best regards.
