816932 - getUserMedia doesn't call success/failure callback nor any catchable error (with media.navigator.enabled == false)

Status: RESOLVED WONTFIX

(Core :: WebRTC: Audio/Video, defect, P3)

Description

[Jean Claveau]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:20.0) Gecko/20121129 Firefox/20.0
Build ID: 20121129074803

Steps to reproduce:

go there http://addyosmani.github.com/getUserMedia.js/face-detection-demo/index.html with firefox 17.




Actual results:

Nothing appends if the media.navigator.enabled is false (as by default). The flash fallback is not launched because 
try {
   getUserMedia(....)
} catch(e) {

}
never catch any error.


Expected results:

The flash fallback should have been launched.

I have got the same problem since my update to Firefox 17.
On Firefox 16 it worked for me.

But it doesn't matter if I change the value of navigator.media.enabled. This feature is always disabled and no getUserMedia example page in the internet is working.

I have tested this on two computers:
1. Windows 7 x64
2. Windows XP x86

Always the same result after the update.

Hmm...the demo works in Chrome, but fails in Firefox. We do get the prompt to appear for permissions, but the camera stream doesn't render.

The demo needs to be updated; the current API consensus is for video.srcObject = stream (and mozilla has implemented it for now as video.mozSrcObject = stream).  This replaces our earlier experiment with video.src = stream.  We also support createObjectURL(stream) now, though we don't recommend it.

The issue remaining here is lack of error/exception when using it when it's preffed off.

Problems trying to use it when it's preffed off are non-blocking

I've tested it with mozSrcObject and I got a screenshot of myself.

But I found out, that Firefox doesn't support audio and video at the same time.

E. g.:
<script>
navigator.mozGetUserMedia({ video: true, audio: true }, function(stream) { alert("Success!"); }, function(e) { alert("Error: " + e); });
</script>

Returns with "Error: NOT_IMPLEMENTED" on FF18.
If I call mozGetUserMedia with either video or audio (but not both) then it works...

Right. You will have to use Firefox 20 which is currently on the Nightly channel. Not sure about Aurora.

We're preffed on by default on all channels now, so this is a WONTFIX.
