GPU hardware acceleration on Rpi 4 with EGLFS

Description

I build a 64-bit system based on "Kirksone" branch and I meet a problem with the GPU hardware acceleration on Raspberry 4/CM4. The problem occurs when playing video directly from GStreamer and QML using QMultimedia and also rendering Qt application GUI in QML (Configuration attached below). I tried also to build an image without Qt and based on a poky distro with GStreamer and core-image-base, but with a similar result.

Steps to reproduce the issue:

Clone all sources listed in bblayers.conf up to date with "Kirksone" branch.
Add gstreamer and ffmpeg to image config.
Build image.
Flash image to Rasberry.
Try play video via gstreamer or from using Qt application and see high CPU usage.

Describe the results you received:

The high use of CPU during play video. Small number of frames.

Describe the results you expected:

HW acceleration during play Video and render application GUI. FFmpeg doesn't list and hw accelerator.

Additional details (revisions used, host distro, etc.):

Maybe I missed something or I doing something wrong. Any way I will be grateful for advice. Below attached bitbake configuratinos.
