webView getUserMedia =>Could not start video source

Bonjour,

J'ai du HTML, CSS, JS qui fonctionne sur un PC avec fireFox pour afficher le flux vidéo d'une webCam et prendre une photo pour l'envoyer en PHP.

Si j'essaie d'utiliser la même chose dans un webView Android, j'ai l'erreur

Citation:

NotReadableError: Coulnd not start video source

function photo()
{	var video=document.getElementById("video"),
	canvas=document.getElementById("canvas"),
	photo=document.getElementById("photo"),
	take=document.getElementById("msgButtonPhotoTake"),
	send=document.getElementById("msgButtonPhotoTake");
	navigator.mediaDevices.getUserMedia({video:true})
	.then(function(stream)
	{	video.srcObject=stream;
		video.play();
		take.addEventListener("click",function()
		{	var draw=canvas;
			draw.width=video.videoWidth;
			draw.height=video.videoHeight;
			canvas.getContext('2d').drawImage(video,0,0,video.videoWidth,video.videoHeight);
			var data=canvas.toDataURL('image/png');
			photo.setAttribute('src',data);
			draw.toBlob(function(blob)
			{	var data=new FormData();
				data.append('upimage', blob);
				console.log("Photo->"+photo.src);
				mailSend("mailVisual",[photo.src]);
			});
		});
	})
	.catch(function(err)
	{		alert(err);
	});
};
