Improve error logging

Log at debug level immediately when MediaCodec throws. This logging will be
output closer to the time when the error actually happened so should make it
easier to identify the order of components failing.

Downgrade logging of errors after export ends to warning level, as output may
still be fine if there was a problem after exporting completed (though it's
still worth logging a warning as the device may not be in a good state).
