Hi Divya,
Which device (SoC) you are using?
You can start with DSS chapter in your device Technical Reference Manual (TRM).

Stan

Thanks Stanislav, I am using TDA2X,
I was thinking that when we generate a usecase there is grpsrc plugins for graphics by which we get the usage of processors so in similar way using those plugins can i send some images which would form an overlay on displayed Image.

There are multiple video pipelines and graphics pipelines on TDA2x, You could use them to send images, which could form overlay or complete display on the target display. It is possible. You could have source image size smaller than the display video size.

hi brijesh,
As suggested the image that I have passed is displayed but its in foreground I want the image to be displayed in background. The background image I am passing through graphics pipeline and the output video is by video pipeline. If there is any flag to display image in background please let me know

Hi Divya,

Yes, You could the change the zorder for different planes.

zorder is part of the Vps_DssDispcOvlyPipeConfig overlay pipe config, Please go through the documentation of these structure to get the idea about the zorder.
