Non-monotonous DTS in output stream 1:0

Describe the bug

Soon after starting frigate the logs fill up with ffmeg errors. I have been trying to find a solution and I see this issue has come up a number of times but there does not seem to be a comprehensive fix.

Is there a way to check what ffmeg command is being called and to test that to prove its ffmeg and not frigate?

The errors are as follows:

I also see:

Could be lots of things. Camera could be overloaded if you are connected from multiple clients. It could be network issues, or your camera just may not output a very reliable stream.
