i.MX7 can't capture high resolution picture base on OV5640 MIPI camera ?

[Danube]

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

Does any ideas or suggestions how i fix this problem ?

Wigros,

I think i.MX7D can process  S/W jpeg encode function base on Gstreamer plug in lib

We are some confuse ,640x480 can work , 

800x600 , 1024x768 fail

Hello Apollo,

    There is no VPU( Hardware encoder) in i.MX7D, so High resolution JPEG encoding can't be supported.

Have a great day,
TIC
