LCCS on Flash 11 Flash Builder 4.6

[Former Community Member]

Hi,

We have moved to flash builder 4.6 sdk 4.6 for our development. We want to incorporate LCCS collaboration in our application. Is LCCS swc for flash 11 going to be available anytime soon? I only see 10.3 version in downloaded sdk.

[Raff_]

The only reason why we have SWC for different versions of the Flash player is because we can't support new feature and keep backward compatibility (i.e. 10.x added support for rtmfp and p2p, and 10.3 added support for echo cancellation) but otherwise you can use any of them with any higher version of the Flash player (I tend to use the Flash 9 version for everything unless I need some of the newer features).

If you are talking about a specific version for Flex 4 (i.e. Spark components) we have an alpha/beta version posted on the forum but development has been stopped so if you want to use it you'll have to take it from there.

Hi Raff,

Thank you for your response and clarification of different sdks.

My interest is to setup a working LCCS sdk for flex SDK 4.6. I am not perticularly interested in Spark components.

I took source code of 10.3 LCCS sdk, in my project and updated video sample to run on Flex 4.6 sdk. When I run the sample I am getting blank screen. Is this expected behavior? Can 10.3 LCCS SDK source code work with Flex SDK 4.6? Or spark components are only option to get sdk working with Flex SDK 4.6? I understand that there is no more new development on LCCS SDK, but can we have atleast a maintenance release compatible with Flex SDK 4.6?

Following is my updated video app sample for your reference. I used correct userid,password and room url when running this sample.
