Summary Canvas.toDataURL incorrectly raises exception when using Media Source Extensions

Reported 2015-10-12 05:30:42 PDT
Hi all, these steps can be followed to reproduce the bug: 1. Create a "video" element, a "canvas" element and its 2d "context". 2. Have the video element's "src" be a "MediaSource" URL (createObjectURL is called for a new MediaSource object). 3. Draw an image with context.drawImage(video, 0, 0); 4. You will not be able to call canvas.toDataURL, because a security exception will be raised (incorrectly). Alex

Ok, this bug is now 6 months old and still has the NEW status :). So there is point in reporting the bugs here... Alex

Ve don't yet support painting MSE video into canvas (see bug #125157). This work (ensuring that painting MSE doesn't taint canvases) will take place in that bug.

We believe this issue is resolved now that Bug 125157 is shipping. If you believe there is still a problem, please REOPEN this radar with a relevant test case.
