Parallel-CSI and MIPI-CSI preview simultaneously on MCIMX6Q-SDP

keitanagashima — Mon, 01 Sep 2014 05:46:41 GMT

Hi Dear Sir or Madam,

I tried to preview from Parallel-CSI(ov5642) and MIPI-CSI(ov5640) on MCIMX6Q-SDP (w/ Yocto L3.10.17_1.1.0)

But it wasn't possible to preview the two input data simultaneously.

Running Parallel camera was OK, but MIPI camera wasn't display.

(See attached log file: Camera_Log140902.txt)

$ modprobe ov5640_camera_mipi

$ 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=640 disp-height=320 motion=2 & gst-launch -v mfw_v4lsrc device=/dev/video1 fps-n=60 capture-mode=4 ! mfw_v4lsink axis-top=320 axis-left=0 disp-width=640 disp-height=320 motion=2 &

Best Regards,

Keita

You can try the following patch:

Dear SerchMX and rogeriopimentel,

Thank you for you reply.

I'll try to test Displaying two cameras at the same time on i.MX6Q.

If I tested it, feedback you.

hi Freescale ,

if i try to capture 720p image using /dev/video1 the image is tiled and not proper.

so, how can i capture 1080p or 720p image using MIPI camera (using imx6) ?

i am using hw : MCIMX6Q-SDP sw: Poky (Yocto Project Reference Distro) 1.5.1 \n \l kernel: 3.0.35-4.1.0+yocto+gbdde708

regards

Hi Nagendra,

How are you capturing the image? Can you send the steps to reproduce?

Regards,

Rogerio
