gstreamer examples #19
Description
Hi,
I successfully configured the module for a 280x240 SPI display.
kmscube displays correctly the cube using EGL (no X Windows / Waylands), got 74fps.
I've been attempting to use gstreamer and display whatever thing on the display, without success.
could you provide working examples of gstreamer working panel-mipi-dbi with optimized interfaces like KMS/DRM and/or OpenGL.
I have been testing:

fbdevsink --> works but sluggish performance
many thanks
