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.

You can use the LEAD MPEG2 Transport Demultiplexer and check the IsStreaming property of the ILMMpgDmx Interface.

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

The "IsStreaming" property can be false when you are playing a file and it does not indicate that the streaming has ended.

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.

Regards,
Mario

The IsStreaming property is not used to indicate that the stream has stopped. 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.
