Gstreamer rkximageisnk

Linux rock-5t 6.1.84-8-rk2410 #8 SMP Thu Oct 16 07:07:35 UTC 2025 aarch64 GNU/Linux

When flashing the RADXA OS image from the RADXA site for a rock 5T board the following gstreamer plug-in does not work, and therefore I cannot get 4k60 to playback on this machine using the rockchip gstreamer plugins.

I have seen this same issue when upgrading the packages on my rock-5b. Is this a known issue when updating a gstreamer package? Which package should I be targetting? I plan to use these boards in a run of products that will rely on this plug-in working.

Thank you for any hints!
@radxa please help, Im going crazy!

I have tested before and after running rsetup and a system upgrade.
I have only had this pipeline working on a rock-5b board using the image provided on the website before running rsetup and a system update. After the update breaks the pipeline.

I believe I’m using the correct method to use rkximagesink:

To get connector-id:
radxa@rock-5t:~$ sudo cat /sys/kernel/debug/dri/0/state | grep connector
connectors_changed=0
connector_mask=2
connectors_changed=0
connector_mask=0
connectors_changed=0
connector_mask=0
connector[213]: Writeback-1
connector[215]: HDMI-A-1
connector[231]: HDMI-A-2
connector[245]: DP-1

To get a non-primary plane-id:
radxa@rock-5t:~$ sudo cat /sys/kernel/debug/dri/0/state | grep plane
plane[56]: Cluster0-win0
plane[72]: Esmart0-win0
plane[96]: Cluster1-win0
plane[112]: Esmart1-win0
plane[136]: Cluster2-win0
plane[152]: Esmart2-win0
plane[176]: Cluster3-win0
plane[192]: Esmart3-win0
planes_changed=1
plane_mask=1
planes_changed=0
plane_mask=0
planes_changed=0
plane_mask=0

This is a NON-Working pipeline Initialisation:

I’ve done some digging and it appears that the DRM susbsystem for the latest kernel has been changed from:
V3.0 (Kernel:6.1.43-26)
to
V4.0 (Kernel: 6.1.84-8)
Which now includes the render atomic request api. rkximagesink plug-in hasn’t kept up with this change, and therefore doesn’t work so I cannot use a full hardware accelerated gstreamer video playback pipeline.

This works on the latest image of radxa OS:

Linux rock-5t 6.1.84-8-rk2410 #8 SMP Thu Oct 16 07:07:35 UTC 2025 aarch64 GNU/Linux

GST_DEBUG=4 gst-launch-1.0 uridecodebin3 uri=file://videofilemp4 ! kmssink plane-id=72

For it to work you have to be switched into a separate tty KMS
