Hi
I didn't get exact issue with pipeline. I think some sort of buffer issue.
I tried with gst-launch-1.0 filesrc location=sample.bgra !
Video/raw,format=BGRx, width=352,height=288, framerate=25/1 ! Waylandsink
The result have same buffer error and a blue line on the display.
Actually I build wayland for RcarE2 using yocto 1.6
Weston version-1.5.0
I don't know which rendering mechanism using because both EGL and pixman
libraries are present in my RcarE2.
Egl library versions
Libwayland-egl1-10.1.3
Libegl1-1.0
Libegl-dev-1.0
Pixman library version
Libpixman-1-0.0.32.6
Please help me to solve buffer issue.
Thanks abin
