Support Required: Wayland-EGL Plugin and Video Playback Performance Issue with IVI-Shell

[Ram2]

Hi NXP Team,

We need your support regarding a Wayland/Weston shell-related issue observed in our Yocto Linux setup.

We are currently validating video playback with kiosk-shell and ivi-shell. With kiosk-shell, the wayland-egl plugin is detected and accessible, and video playback is working smoothly without frame drops or system hang. However, with ivi-shell, we are not able to access/get the wayland-egl plugin properly, and video playback is showing frame loss and intermittent hang.

Please find the issue summary below:

Item Observation

Platform	i.MX8QXP C0 MEK
OS	Yocto Linux [ Scarthgap L6.6.5]
Weston Shell 1	kiosk-shell
Weston Shell 2	ivi-shell
Graphics Interface	Wayland / Wayland-EGL
Video Playback	GStreamer-based playback

Observation

Test Case Result

kiosk-shell + wayland-egl	Plugin is available and accessible
kiosk-shell + video playback	Video plays smoothly without frame loss or hang
ivi-shell + wayland-egl	wayland-egl plugin is not getting detected/accessed properly
ivi-shell + video playback	Frame drops and intermittent hang observed

Support Required

Could you please help us with the below points?

1. Is wayland-egl fully supported with ivi-shell on i.MX8QXP Yocto Linux 6.6.5 version
2. Are there any specific Weston, IVI-shell, or compositor configuration changes required to enable wayland-egl with ivi-shell?
3. Is there any recommended weston.ini configuration for ivi-shell on i.MX8QXP?
4. Are there any known limitations with ivi-shell for video playback or GPU-accelerated rendering?
5. Is there any reference document, patch, or example application available for ivi-shell + wayland-egl + video playback?
6. Could the frame loss/hang be related to compositor configuration, buffer handling, GPU/VPU integration, or GStreamer sink selection?

Request

Please provide your guidance, recommended configuration, and any available reference documents or patches to resolve this issue.
