VideoRecorder.startRecording crashes Android with IOException "prepare failed"

[disbelief]

When calling VideoRecorder.startRecording the Android app crashes with an IOException and message "prepare failed". The stack trace goes all the way into the MediaRecorder._prepare native method. I have attached a debugger to just before this call and can see that the MediaRecords does have a valid mPath for the file to write to.

Here are the logs when startRecording is called:

I can see that the output video file does get created on the device, but it remains empty (size 0 B). So I think this indicates that IO to the file is not the problem. The file is being stored in the private data directory of the app, any of the shared system directories (eg. "Photos" or "Movies").

As can be seen in the manifest both CAMERA and RECORD_AUDIO permissions are specified, and I can confirm that the app requests the correct permissions from the user.
