Hi

 

CPU : i.MX7D

Kernel Version

Yocto_4.1.15_2.0.0

 

Issue

test the OV5640 camera on i.mx7, it always hangs when it captures the picture with the resolution higher than 640x480.

 

 

command :

gst-launch-1.0 imxv4l2src device=/dev/video1 num_buffers=1 ! video/x-raw,format=YUY2,width=1920,height=1080,framerate=30/1  ! jpegenc quality=100 idct-method=2 ! filesink location=test.jpg
