I am using a blackmagic ultra studio mini (sdi to thunderbolt) to get video with embedded audio into OBS studio. I have noticed that when I stream, the audio will go out of sync with the video over time. I am having trouble correcting this with a delay on either audio or video as It seems to desync more and more over time.

My questions are:

Is there a simple way to refresh your source or the embedded audio with out completely recreating the scene/source?

Could this have to do with dropped frames during my stream?

Any advice/insight/reccomendation is very welcome! Thanks!

@rcombs are you using the last binary ? this issue should be fixed. The Blackmagic device is not always providing correct timestamps; this was fixed by Jim with a manual computation of the timestamps
