Cannot read property 'chooseDesktopMedia'

问题:

I am working on desktopCapture API of google chrome webrtc. When I run the application I am getting error "Cannot read property 'chooseDesktopMedia' of undefined". Means browser is not able to find the chrome.desktopCapture inside chrome browser.

My chrome browser version is 38.

Yep, access to the desktopCapture API is disabled by default. You either need to write an extension or modify the browsers internal flags.

I wrote such an example extension which might be helpful.
