SHM sink waiting for connection

[Takido]

Hello,

I managed to extract a stream from Gstreamer using shmsink, and it works correctly when the property "wait-for-connection" is set to false.
I'd like the property to be set to true so that the stream starts only when I want it to start. However, when I set it to true, the stream never starts. I saw that there is something to do with signals (client-connected) but how can I emit such a signal from a non-gstreamer application ?

Thanks.
Hamza

The "client-connected" signal is just informative for the application.
Did you copy shmpipe.[ch] into your own application? Or are you using
some other mechanism? If "wait-for-connection" is true, the sink should
unblock as soon as at least one client is connected.

Yes, I did exactly what is written in the header of shmpipe.h.
I don't understand why it doesn't work as it should. Well, if I don't find any solution to this problem, I'll just make the client connect as soon as the stream starts, but it's not the best way..
