Bug ID: 166758
Summary: using sWidth and/or sHeight not matching video source
in drawImage crashes safari
Classification: Unclassified
Product: WebKit
Version: Safari 10
Hardware: iPhone / iPad
OS: iOS 10
Status: NEW
Severity: Normal
Priority: P2
Component: Canvas
Assignee: webkit-unassigned at lists.webkit.org

if you use the drawImage method with a video as a source and change the source dimensions (skewed or scaled proportionally) safari crashes after a couple of seconds, current workaround is to change the dimension of the canvas and reposition/crop the canvas itself

void ctx.drawImage(image, sx, sy, sWidth, sHeight, dx, dy, dWidth, dHeight);
