Hi,  I'm trying to use your toolkit in a c# project vs2005, but I'm begginer in DirectShow and I'm sure that I don't know to use it correctly. I expose you my needs; my project receives 4 to 16 simultaneous UDP MPEG2TS streams,  it has to add overlay image, text and timestamp and shows and captures each stream in localmachine and sends by UDP the new streams with overlay. In MPEG2 UDP transport source/sink  modules, is there any event about the state of UDP transport, for instance, what happens if a UDP source stream finish, i have a callback notification or something like this?? forgive me for my poor english and thanks in advance,         Mario Cruz.    Report

Adnan,   I've checked your solution with ILMMpgDmx Interface and its property IsStreaming is always true when you receive UDP stream but it doesn't change its value to false when UDP stream stops. Maybe, Video callback filter??  Thanks,          Mario    Report

Adnan ,  I try to check it again, but in my tests when UDP stream stopped, IsStreaming property didn't change....before that UDP Stream starts its value is false, changes to true value when receives UDP stream, but doesn't change when UDP Stream finish.  Anyway, I can check it again.

It only tells you whether the playback was from file or streaming data. If you are using our LMNetConnection Object, you can use the ILMNetConnection::IsConnected method to check the connection status. Adnan Ismail LEADTOOLS Technical Support    Report
