Playback of H.264 should be supported on all Windows Phones, but encoding
looks like it is device specific.
It may or may not return H.264, but in reality most Windows Phones probably
do support it. I am not sure.
I don't think it would be possible to download and use the Cisco library
though.

The future is uncertain. I have no idea if new platforms will popup without
H.264 support.
