Currently only H.263 is supported with H.239. You need to add the PluginCodec_MediaTypeExtVideo to the H.261 plugin codec definition to tell h323plus to load it into the H.239 plugin factory.

Hi everyone

I was trying to make a call using H.261 codec and then I opened ExtendedVideoSession. The session opens and closes immediately. I guess it is because the call was established using H.261 codec so it returns from the library,

Does anyone have any idea about these.

...

Is H.261 plug in supporting extended session or not? Does Extended session use the same codec as selected for main video

channel or it can use a different codec. If yes how can we specify a different codec for extended channel?

Thanks
