Thanks for reporting. Do you know what triggered it?

[Sean-Der]

This is right on startup! This also always had the visual corruption.

I don't know the AVFoundation APIs, is it possible that you aren't getting back the pix_fmt you expect?

[maxhawkins]

The camera doesn't activate until the intro animation is done. Could it be the ivf reader for the intro?

[Sean-Der]

Sorry right on startup for the camera, the videos do play correctly!

[maxhawkins]

Good to know!

I bet the camera doesn't support the dimensions we request and is sending different ones. I'll look into this...

[Sean-Der]

Oh good idea.

If you have any debugging code I can run send it my way and can test it out!

It appears #25 and this issue are related.

When I launched Photo Booth I got this error

[maxhawkins]

1. This should return an error rather than panicking
2. Maybe this has to do with the image dimensions changing to an unexpected size

[maxhawkins]

Possible solution to 1)

Pass the frame size in the cam_avfoundation callback. If it's different than expected the code will scale it anyway.
