Issue using Windows 10 with Firefox ver52 (32-bit)

Hi Mauz,

When I try screen capture + microphone from this demo page https://www.webrtc-experime..., using Windows 10 with Firefox ver52 (32-bit), when i press "Stop Recording" the video is not generated and the button just returns to "Start Recording".

please note that when i access the same page, using mac and firefox ver52 (64-bit), the demo page works and after click "Stop Recording" the button "Open in New Tab" appears.

Hi,

Any updates on this?

I'm having the same issue using Firefox 52.0.2 (64-bit) on Ubuntu 16.04.3 LTS and Firefox 52.0.2 (64-bit) on Windows 10. When I start recording a screen, browser console also gives me the following message:

The UA cannot provide the codec or recording option that has been requested. error { target: MediaRecorder, isTrusted: true, name: "GenericError", currentTarget: MediaRecorder, eventPhase: 2, bubbles: false, cancelable: false, defaultPrevented: false, composed: false, timeStamp: 695969.382953, cancelBubble: false }

I also use RecordRTC library in a screen recording project and I noticed that whatever operating system I use the callback function of the method stopRecording(callback) is not called in Firefox. That causes the recording is not actually stopped and browser continues capturing screen (and microphone). In Chrome the method in question works as expected.
