All I see is info on RTSP (not sure if I should use this?) and that "newer" android devices support RTMP. Does this mean we need an application, or what? Trying the direct RTMP://blah:port/live simply doesn't work.
For Android 2.2+ you can do RTMP streaming to a Flash app same as you would Flash app on desktop. You can also do Flash HTTP (Sanjose) streaming with an OSMF Player. Strobe and Flash Media Playback will do RTMP or Flash HTTP:
If the Android device supports Flash, you can use a Flash RTMP client, like Wowza examples or JW Player. You just navigate to the player in Android as you would on desktop, and configure with Flashvar streamer with rtmp or rtmpe protocols
