I think D-Bus could be used for this  but I am not shure that it will realtime.

As for me, I whould prefere to use Mediastreamer2 or GStreamer (both can provide RTP-streams for video/audio ) for videodata transfer, processing by custom filters. And  D-Bus  between PC's for control messages.


Best regards,
Igor

How are you defining "real-time application" here?

And as you are dealing with a network, how does "real-time" come into
play at all?

I doubt it, as dbus as written, is not across a network, right?

good luck!
