  1. Start a FaceTime Video call or phone call.
  2. Open an app that uses PBJVision as the viewfinder in Video mode.

The preview layer flashes like a strobe light, with the log being spammed by errors.
Trying to record does starts "recording" but doesn't actually record anything.

Did you ever figure out this issue? I have the same with just a normal phone call

No. I did notice that the Video output of the FaceTime call gets paused when in the background. This leads me to think it might be audio related.

commented

I suspected that it is an audio thing. I try to test the instagram app's video just to see if it was PBJ specific or a general iOS thing. the app seemed to behave fine showing the camera view at the same time. So must mean it's something with PBJVision/PBJVideoPlayer

commented

the library doesn't fully support backgrounding. unfortunately, i'm not sure when i'll be able to get that added. but it's tracked here:

📎 #2

commented

This isn't an issue with PBJVision being in the background, it is an issue with PBJVision being in the foreground with a call in progress in the background.

This issue occurs without the app using PBJVision being sent to the background.

commented

yeah, @piemonte set this up to use audio samples but it seems like the phone call is causing an issue with collecting those samples properly. he's supposed to fix it with #2

commented

thx, yep.

📎 #178
