you can download 8qxp demo images from nxp official website, then download them to your board, as I known, you can use the default dtb named Image-fsl-imx8qxp-mek.dtb, after board boot up, you can use the gstreamer command in my document to test
maybe you can refer my another document for imx8mq:
how to play the two different video to the different display
这个例子无从下手,有个简单代码就好,或者有个针对imx8qxp例子最好。
