Help with rsvgoverlay plugin

[ravi.modha]

Hello All,

I am a newbie in the GStreamer and I have a requirement to use rsvgoverlay but I am getting an example of how to send SVG data at the runtime in the pipeline. 

Can someone help me or give me an example of it, please.

Hi

You have multiple options, as documented on
https://thiblahute.pages.gitlab.gnome.org/gnome-devel-docs/rsvg-1.0/rsvgoverlay.html

You can either set the data property of the rsvgoverlay element to the
SVG code you want to display (for dynamically generated svg), or set
the location property to the filename of the svg file you want to
display. You can also feed the svg data to the data_sink pad.

I join a python example, where a dynamically generated svg is updated
every second.

Olivier

Hey Olivier,

Thanks for the reply. Can you please help me, how do I feed the data to the
data_sink pad. As I never used GStreamer before, if you can help me here to
understand how to feed the data to the data_sink pad, it will be very
helpful.

Thanks,
