Mediarecorder start failed -19

Question

I am getting this error when running start() for mediarecorder.

06-28 18:46:22.570: E/MediaRecorder(9540): start failed: -19
06-28 18:46:22.570: W/System.err         


        

Answer 1

I found a subtle hint in documentation for the MediaRecorder.start() method that suggest if it fails to lock() the Camera before attempting to re-record. This worked for me. Implies a Camera state bug was fixed post API level 13 - calling Camera.lock() is the known workaround.
