Hi,
I would like to play a video by using GStreamer on a screen. Previously, this worked with the 'multimedia' image downloaded from NXP. Now, I would like to play the video using the "imx-image-full" image.
I have built an "imx-image-full" image by using the i.MX Yocto Project for i.MX8qxp b0 mek. (DISTRO=fsl-imx-wayland. libavtp was added to GStreamer. It was compiled successfully. It shouldn't course any problem.) I download the image to the board. The Linux system runs.
However, no 'desktop' shows on the connected screen. (IMX-LVDS-HDMI was used to connect the board and a screen. The screen also shows 'no signal' message) The terminal reports errors and failure about 'weston' when I try to play a video by using GStreamer. The error mesaage is listed below. Can you please let me know why the problem happend and how to fix the problem?
