Re: Video Stream Application

[Bernd Robertz <bernd robertz cssweb de>]

Hello,

first, thank you for you answer. I think that is a base wich I can build
on.

So simply you mean, I can use gstreamermm and giomm to get this work?
I don't habe any expierence in one of them, but I think this should be
an achievable goal.

Many thanks for you help.

Bernd
