[FFmpeg-user] "Failed to update header with correct duration."

[basteon]

Hi,
If you still not solve this. That when bmdcapture loosing one frame rtmp
could be confused about timebase of that frame. If you using -copytb.

That will happening for video, audio or both?
for flv you can try nellymoser.
