Dear Sir or Madam,



BSP: L3.10.17_1.0.0

I'd like to execute the preview function with 720p@60fps from Parallel camera (ov5642) to LVDS or HDMI display on i.MX6Q SABRE-SDP.

[Flow: Camera (OV5642) 720p@60fps --> CSI --> DDR3 --> HDMI or LDB 720p@60fps]

Anr, I tried to below commands.


$ modprobe ov5642_camera

$ modprobe mxc_v4l2_capture

$ gst-launch -v mfw_v4lsrc device=/dev/video0 fps-n=60 capture-mode=4 ! mfw_v4lsink disp-width=1280 disp-height=720 motion=2



The preview image was possible to display on LVDS or HDMI display.

But, the render fps was 29.953.

Refer to below log.

Could you tell me the way of preview 720p@60fps from Parallel camera?
