Hi all,
I’m running an application with the i.MX8QMand have used gstreamer pipline for display CSI Camera that using the imxcompositor_g2d

I want to use a pipeline using imxcompositor_g2d and multifilesrc png file but faced an error (multifilesrc and imxcompositor_g2d)
bellow is comparing the following two pipelines Pipe#1 have run without error:

Pipe#1

root@apalis-imx8:~#gst-launch-1.0 multifilesrc location=“/home/root/feeds-st.png” caps=“image/png,framerate=1/1” ! pngdec ! imagefreeze ! videoconvert ! waylandsink -v

output is ok and display picture

Pipe#2

root@apalis-imx8:~# gst-launch-1.0 imxcompositor_g2d name=comp sink_0::width=460 sink_0::height=288 ! waylandsink multifilesrc location="/hroot@apalis-imx8-06506314:~# gst-launch-1.0 imxcompositor_g2d name=comp sink_0::width=460 sink_0::height=288 sink_0::xpos=160 sink_0::ypos=120 ! waylandsink multifilesrc location="/home/root/feeds-st.png" caps="image/png,framerate=1/1" ! pngdec ! imagefreeze ! videoconvert ! comp.sink_0 -v Setting pipeline to PAUSED ...

feeds-st.png is a 25x25 pix image.
Maybe there is conflict configuration between tow pipeline!! What should I do?Can anyone guide Me?!
