8MMINILPD4-EVK imxvideoconvert_g2d broken frames

Hi, I attached a USB camera on my 8MMINILPD4-EVK running Linux image L4.14.78_1.0.0_ga_images_MX8MMEVK.

 

The following gstreamer pipeline works fine:

gst-launch-1.0 v4l2src device=/dev/video1 ! "video/x-raw,format=UYVY,width=640,height=480" ! videoconvert ! autovideosink

 

But when I replace videoconvert by the accelerated imxvideoconvert_g2d, I get broken frames which look like uninitialized memory intermixed with old image fragments.

 

Am I missing something? What is the roadmap of video acceleration (2D, 3D GPU) support in Linux?

 

Frank
