• I have used Google with the error message or bug in association with the library and Cordova words to make sure the issue I’m reporting is only related to iOSRTC.
• I have provided steps to reproduce (e.g. sample code or updated extra/renderer-and-libwebrtc-tests.js file).
• I have provided third party library name and version, ios, Xcode and plugin version and adapter.js version if used.

Note: If the checkboxes above are not checked (which you do after the issue is posted), the issue will be closed, removing this checkbox will result in automatic closed issue.

Description

It appears that the plugin doesn’t emit the necessary data for canvas drawImage(videoElem…) to function (capture the current frame basically) this prevents libraries like https://github.com/zxing-js from working.

Steps to reproduce

canvas: CanvasRenderingContext2D; videoElem: HTMLVideoElement;

canvas.drawImage(videoElem, 0, 0); // Doesn’t error but data isn’t valid

Expected results

The frame should be copied over

Actual results

Nothing is copied over
