Comment (by vestigal):

 Replying to [comment:12 finalweb]:
 > Looks like that works for the live stream, but once you try to record,
 you end up having sync issues with the recorded file, so that doesn't seem
 to completely resolve the issue.

 I had audio/video syncing problems too, but not just with recorded streams
 I had them with the live transcoded stream also. My guess was that the
 sync problem was a result of transcoding audio; not because of the
 nonstrict timestamp flag.

 I had some excellent results using the -copyts flag. Your result may vary.

 I'm still curious why the AVFORMAT_TS_NONSTRICT flag isn't considered a
 good solution. My understanding of a monotonic function doesn't preclude
 two identical timestamps. Monotonically increasing, in my head, means that
 the timestamps never go backward.
