Google Cast Beta for Chrome
More About Google Cast Beta
This is the *BETA* channel of the Google Cast extension. It is intended for developers and advanced users who want early access to upcoming APIs and features in advance of public release. Most users should install the stable Google Cast extension (https://chrome.google.com/webstore/detail/google-cast/boadgeojelhgndaghljhdicfkmllpafd). The beta channel will often be less stable and contain more bugs.
