Hi,
I'm new user, I'm using the qtwebkit-5.212.0_alpha2-qt59-mingw530-x86.zip
and I want to show video on canvas, example context.drawImage(video,0,0,width,height);
But it can't show video and I got these errors:
"IndexSizeError: DOM Exception 1: Index or size was negative, or greater than the allowed value"
"SecurityError: DOM Exception 18: An attempt was made to break through the security policy of the user agent"

Could you help me how can I resolve it. Thank you very much!
