A/V drift after unpluging HDMI #17

Open nrmmota opened 8 years ago

nrmmota commented 8 years ago

If I unplug and plug HDMI back again the audio video drifts apart a few ms.

The only way to fix this is to restart the avconv process. Is there a way to signal avconv upper layer to reset the decklink capture?

Possibly we can have a specific return value and on the avconv side try to adapt but I'm not really sure something more than have an EOF simulated in the situation could be done if the drift is caused in the decklink side.
