Hi - 

My mistake, I must've deleted an object from the manifest.json right before uploading. Problem's fixed in the attached files.

Figured out the reason for this - the video streamed to the background page wasn't being auto-played due to the latest changes to auto-play. Therefore, adding video.play() was necessary to start the streamed video and grab a screenshot.

Working background.js attached.

As per comment# 3, we need a sample extension to check and confirm the issue from our end, as it would be out of scope for us to proceed further with the provided '.js' files, hence adding TE-NeedsTriageHelp label for further triaging the issue.

Thanks!
