var canvasDraw = document.getElementById(‘imageView’);
var w = canvasDraw.width;
var h = canvasDraw.height;
var ctxDraw = canvasDraw.getContext(’2d’);

ctxDraw.clearRect(0, 0, w, h);
ctxDraw.clearRect(0, 0, w, h);
ctxDraw.drawImage(video, 0, 0, w, h);
_________________________________________________________________
The above works perfectly.
Below is the code to get the dataURL:
_________________________________________________________________
function getURIformcanvas() {
var ImageURItoShow = “”;
var canvasFromVideo = document.getElementById(“imageView”);
if (canvasFromVideo.getContext) {
var ctx = canvasFromVideo.getContext(“2d”); // Get the context for the canvas.

var ImageURItoShow = canvasFromVideo.toDataURL(“image/png”); //<– It fails on this line.
}
var doc = document.getElementById("txtUriShow");
doc.value = ImageURItoShow;

}
_______________________________________________________________
It always fails on the line:
var ImageURItoShow = canvasFromVideo.toDataURL("image/png");

Any thought on what might be the problem. If I load a normal image into the canvas it works fine, but as soon as I load the image from video into the canvas that line fails.

Any ideas?

now that it’s on 4.2 I can try and see if they updated something, and ‘ll update my blog.
