New popup window created by Chrome extension does not show video streamed via WebRTC on WebApp

[Ricardo De Lemos]

HI,

I have an WebApp that creates a WebRTC peerconnection and I have a video call between 2 browsers. Now, i want to "pop-up" the video in a new window, and for that, I have an extension that creates a new window via chrome.windows.create, and then I inject a content script on this new window to allow the communication between this new window and the extension. All working fine.

The issue is that I pass the videoUrl displayed on my WebApp to the content-script, and use it to update the <video> element of new window. The issue is that I always get a 404 (below).

I did a quick test using window.open to create the window (from the WebApp, instead of the extension), and update the video URL via a jQuery function, and it works.

Failed to load resource: the server responded with a status of 404 (Not Found)                  blob:https%3A//vmw-server.yourcircuit.com%3A8094/e08e3d13-ddf5-400c-bbe9-afccd0d8a704

Could this be caused by the Content Security policy? if yes, how can I overcome this?  Do I need create a new peer connection on the new window created by the extension, or there is a way to use the videoUrl provided by the WebApp??

Media stream blob:-URLs are only known to pages/tabs within the same process.
Same-origin tabs opened using window.open() are hosted in the same process as the opener, whereas tabs that are created using chrome.tabs.create are always opened in a new process. That's why you're observing different behavior for seemingly equivalent actions.

You should call getUserMedia from the page/frame where you intend to you use it.

Kind regards,

 Rob

Thanks Rob,

I have suspected that it was something related to the same origin policy. What I plan to do is start a new peer connection from the new popup window created, and forward the remote media from the original window to the pop up window.

Ricardo,

Can you shed some light on how did you succeed to implement this?
