Turning off the device between recordings

I want to be able to turn off the camera when the user has pressed the stop button (for privacy reasons). I know, there is a stopDevice method and it works as advertised. It turns off the recording device. So I can call this method after the user clicks the stop button. But the problem is that if I stop the device and the user clicks record again the recorder stops working. I get an error: DOMException [InvalidStateError: "An attempt was made to use an object that is not, or is no longer, usable" code: 11 nsresult: 0x8053000b

I understand that the MediaRecorder gets destroyed after the device is turned off. But is it possible to reinitialize the recorder somehow? I also tried manually calling getDevice but it results in all kinds of strange behaviors (not being able to stop the new recording, no play button…).

So is it possible turn the device off and on again somehow between recordings?

@alsar you can do this:

• after stop record is pressed: player.record().stopStream() to stop the devices
• set processing to true: player.record()._processing = true; (this will block the start button)
• listen for record btn click once: player.recordToggle.one(['tap', 'click'],
• and in that callback handler you call getDevice and set _processing back to false (after deviceReady event fired) so start button works again

Does that work for you? Perhaps it can be a new option, turnOffDeviceAfterRecord (with a better name of course).

Update

this works for me (with v2.0.0):

// user clicked the stop record button
player.on('stopRecord', function() {

        // user completed recording and stream is available
	player.one('finishRecord', function() {

	    console.log('stopped recording, turning off devices...');

	    // stop device stream only
	    player.record().stopStream();

	    player.recordToggle.one(['click', 'tap'], function() {
	        // start device and recording
	        player.record().getDevice();
	    });
	});

});

And adding this functionality behind a new plugin option shouldn’t be too difficult, but what’s a good name…

please open a new ticket with some code that reproduces the problem.
