hi there,
 
I'm trying to do object detection using usb camera via v4l2src on QCS2210.  
The problem I am encountering is  qtimletflite requires GBM memory support.
 
This is the command.


/ # export XDG_RUNTIME_DIR=/run/user/root && gst-launch-1.0 v4l2src device=/dev/
video0 ! video/x-raw,format=YUY2,width=1280,height=720 ! videoconvert ! qtimletf
lite config=/data/misc/camera/mle_tflite_config.json model=/data/misc/camera/det
ect.tflite labels=/data/misc/camera/labelmap.txt postprocessing=detection ! qtio
verlay bbox-color=0x0000FFFF ! waylandsink x=960 y=0 width=960 height=540 async=
true sync=false enable-last-sample=false
 

This is the log of what I'm getting.

Any suggestions on this?
