parleys.com video streaming infrastructure

I was wondering does anyone knows what video streaming infrastructure these guys are using.Front end(gui) is clear which technology these guys are using. On the net I found streaming servers are available, from flash, wowza and red5. From this link

red5 seems 开发者_开发问答to have a bit bad reputation, is it so? has anyone used it? how was the experience?

I dont want to use third party host for streaming. Any suggestions to achieve the same on java based technologies.

Thanks in advance......

They are using RTMP (Real Time Media Transfer Protocol). You can use RTMPDump (a free utility) to save streaming media to your disk.
