The PVideoInputDevice class has GetFrame, GetFrameData and
GetFrameDataNoDelay to do that. That is the reason I asked if you had
studied the video input plugin interface...

It doesn't sound correct: you're modifying gnomemeeting itself, not
writing a new plugin.

You can use the PVideoInputDevice api, as I pointed out. I don't know
exactly how to combine the signals, but openmcu does it, so you'll
probably find some code there...

Notice that the path I point you to will make it possible to keep
compatibility with other h323 clients. On the contrary, I fear the path
you're following means patching gnomemeeting and openh323, and means the
other end needs to use the same thing as you. I can't say for sure,
because you've been short on details for now...
