The issue
Our app makes multiple short recordings of 5-6 seconds while it's running. But when it reaches an amount of recordings (always around 230-250) the plugin gives the error:
[AVProMovieCapture] Failed to create recorder
And XCode shows:
(MCVideoRecorder.m:949) Failed to start writing, error: The operation could not be completed
After this error we cannot make more recordings even if the app is restarted or reinstalled. The only workaround is to restart the iPad. We think it can be related to mediaserverd but we aren't sure.
The method StopCapture() is called without parameters (so it doesn't delete the video directly) but the code does delete the file and Dispose() the handler at a later state (we need to wait a bit for the app to upload the video to the cloud).
We observed that the app works correctly in the editor too.
Any idea what's happening?
Thanks in advance!
