Flazr 0.7-RC1 experimental RTMP server with H.264 support
I've implemented a minimal RTMP server with H.264 + RTMPE support at http://flazr.com (LGPL)
It is all still very new, I would appreciate feedback. It is a less than 1.5 MB download, so please do try it, you just need Java 6.
Apologies for hijacking the Red 5 list, but I'm not the only server dev ;) here and hope the code out there as open source will prove useful. I would be especially interested in knowing if it works well on Android / Flash Lite - I remember a recent thread on this. Other things to look out for are seek and pause support, Flash player compatibility etc. There's also some interesting stuff like an RTMP proxy server available.
