1182938 - getUserMedia fake constraint always returns 640x480 resolution

Status: RESOLVED DUPLICATE of bug 1088621

(Core :: WebRTC: Audio/Video, defect, P2)

Description

[Philipp Hancke [:fippo]]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/43.0.2357.81 Chrome/43.0.2357.81 Safari/537.36

Steps to reproduce:

call getUserMedia with a resolution constraint (e.g. for 640x360) and fake: true and attach it to a video element. The following snippet does that:

var vid = document.createElement('video');
vid.onresize = function() { console.log(vid.videoWidth, vid.videoHeight); };
navigator.mozGetUserMedia({fake: true, audio:false, video: {width: {exact: 1280}, height: {exact: 720}}}, function (stream) { vid.mozSrcObject = stream; }, function (err) { console.log(err); })


Actual results:

the resulting stream is 640x480


Expected results:

the resulting stream is 1280x720, the width/height constraints are ignored.

Would be useful for tests.  Note that we may not want to return the requested resolution, but instead mimic a camera with a set of resolutions (352x288, 320x240, 640x480, 1024x768, 1280x720, 1920x1080, etc.)
