If it is possible to transfer non-media data with rtp?

[Ugly Face]

I have a data source generating non-media data and want to transfer it with no delay, I don't know if I can transfer these non-media data with gstreamer? Need I custom new element?


Say, the data is point user touch on screen, I want to display one user's touch on another user's screen with no delay.

Any help will be appreciated.

Maybe for such purpose, you can send plain UDP frames, even without GStreamer? GLib/GIO has nice bindings for that, all code should fit on one screen.

Obviously you can do this via GStreamer (udpsrc/udpsink will accept anything you drop into it) or via RTP (but then you have to write payloader/depayloader).

If it's really about X/Y of the mouse cursor and you can safely assume that UDP frames will arrive to the receiver (but it's an issue to consider also with RTP) I would have used plain UDP.

If you want to send this as a separate stream, you could send it as KLV
metadata, GStreamer has RTP payloaders and depayloaders for KLV.
