Protrocol in Flash Player 10.x is not compatible with Flash Player 11.x when using video stream multicast

Question

I have a swc plugin embedded in my product to stream live video to a group of recipients.

The plugin uses the NetStream, NetGroup, and NetConnection objects, the server I use to handle the RTMFP session is Influxis.

One client creates a group as a publisher, and stream a live video. His Camera is enabled and I can see the video on the screen as well. The others connect to his group and play the video. Peer assisted Networking is enabled for both the publisher and the recipients.

The plugin worked well in all 10.x versions (10.1/10.2/10.3)

However, when upgrading to flash player 11.x, it stopped working.

• 11.x to 11.x isn't working.
• 10.x with 11.x isn't working.

Only 10.x to 10.x is working.

The server I use to handle the RTMFP protocol is Influxis.com I sent them the same question as well.

The weirdest fact is that I'm using flash builder 4.6 with 4.6 SDK, which is aimed for flash player 11.1, and it is only working with 10.x flash players.
