[machlee]

Hello...?

I'm tring overlay ov5642 video to hdmi on i.MX6Q Sabre LIte.

/unit_tests/mxc_v4l2_overlay.out -iw 1920 -ih 1080 -it 0 -il 0 -ow 1920 -oh 1080 -ot 0 -ol 0 -r 0 -t 50 -d 0 -fg -fr 30

But the hdmi video looks being cut vertically a little and there a lots of warning in console like this.

How can I fix this...?

I don´t have an sabre lite with your camera, so I will not be able to work to reproduce your issue.

Could you, please, take a picture of what you´re seeing?

What´s you kernel command line?

I have cleared this issue.

It was caused by ov5642.c camera sensor device driver which was configured as 50Hz and nothing of table for 1080p, 30fps.

Sorry for late update.

Thank you.

My Board is i.MX6Q Sabre Lite.

I need to encode video resolution of 1920x1080 in h.264 with the command like below.

/unit_tests/mxc_vpu_test.out -E "-o 0414_01_1080.h264 -f 2 -l 0 -c 100 -r 0 -w 1920 -h 1080 -b 0 -g 0 "

but I have failed.

As I had found above, the censor device driver for ov5642  don't support register addresses and values table

for 1920x1080, 30 fps. I tried to make those table but it was very difficult and time consuming work.

I know that the ov5642 cmos sensor support up to 15 fps in resolution of 2592x1944

and then why nothing for 1920x1080 30fps..?

Is there any way I can get that table... or any hint...please...

The sensor can support but the kernel driver does not.

As I know, you need to contact the camera provider in order to get access to this table. I don´t have this as well.

Thank you for your prompt reply.
