Aircast Beta 2 released (chromecast direct media streaming)
I just tried it out
(it mainly fixes some issue with the HTC ONE)
and it works FLAWLESSLY !!!
You can now directly stream video and other media content from android stored on your phone. No rooting or special versions of android needed, just install the .apk. If this is like the one released earlier it will probably be disabled since it's for testing. But it's basically done and finished as far as I am concerned. It works, and well.
All HTC One uses (i.e. people with good taste) with a chromecast should try it out.
