Could not display a video on a screen with cubox-M with buildroot system

NXP i.MX8M Plus

Hi,

I am using a cubox-M with a custom buildroot system.
I am trying to display a video with gstreamer.
I use this command:
gst-launch-1.0 playbin uri=file:///root/background_video.mov
I know that is working on a yocto image but on my buildroot system I have this type of error:

# gst-launch-1.0 playbin uri=file:///root/background_video.mov

and nothing is displayed on my hdmi screen.
However, I am able to display an image with fbv.

In my defconfig I have selected:

I have mainly focused on the Yocto builds. I will review the BuildRoot kernel and update patches by Monday to try and rectify this issue.

Great thanks!
Indeed, it was working correctly on yocto

Hi!
Did you find any correction for the problem of gstreamer on the Buildroot system?

There is way more missing in BuildRoot than I expected for fully working iMX8M Plus. I will get it, but it will take a bit more time than I anticipated.
