Steps to reproduce

  1. Run the camera example app
  2. Select a camera
  3. Start recording
  4. Switch to a different camera (this currently doesn't work because of this issue, but I will merge a fix for it shortly)
  5. Stop recording
  6. Take a picture

Expected results

Picture is taken and saved

Actual results

Crash with an exception

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVCapturePhotoOutput capturePhotoWithSettings:delegate:] No active and enabled video connection'
*** First throw call stack:
(0x18a50d2ec 0x187991a7c 0x1a967fcf4 0x100e57514 0x100e4c9c4 0x100e465f0 0x101aa4584 0x101abe064 0x101aac91c 0x101aad5a4 0x101ab9894 0x101ab8eb0 0x214971660 0x21496e9f8)
libc++abi: terminating due to uncaught exception of type NSException

Code sample

The issue can be reproduced on the current (hash: 8d01cd9a48399d52821e35212644037bdbe8eab7) camera example app (not the camera_avfoundation example app because IIRC it blocks switching cameras during recording)

Screenshots or Video

No response

A bit more context:

  1. There are some fairly obvious issues with the setDescriptionWhileRecording that I've noticed before that may be related to this issue comment
  2. It seems this issue was already reported earlier but without a concrete steps to reproduce 131916, 144975
  3. I'm currently working on migrating camera_avfoundation to Swift and will be migrating the FLTCam class in a next PR which includes setDescriptionWhileRecording but I will translate it as close to verbatim as possible so this shouldn't affect this issue
