Hi!
I am new to gstreamer and I think I have a very basic problem, which I am
still unable to solve!

So I have reduced my pipeline, because I was unsuccessful with my real one
:)

So my pipeline is: appsrc ! appsink
I keep sending data to pipeline, but I only received one event on appsink
and than it all stops :(
Why? How to solve it? I puted queue in between, but the problem is the
same....I need to some how tell the pipe that I want the party to go on :)
How? :)


By default, you only get a new event if you have emptied the appsink queue.
So keep pulling until it's empty en it should work.
