Capture from OV8858

I'm trying to capture via 8MP camera, OV8858.

root@intel-aero:~/work# C=4 INPUT=0 MODE=PREVIEW M_F=NV21 ./capture_example --userp -d /dev/video0

Preview mode: 640x480, nv21.

m_width 640, m_height 480, m_sizeimage 462848, m_padded_width:640, bytesperline 640

Saving file: Image-video2-640x480-0.nv21

Saving file: Image-video2-640x480-1.nv21

Saving file: Image-video2-640x480-2.nv21

Saving file: Image-video2-640x480-3.nv21

Preview: Time=141.286000ms FPS=28.311368

And I can get images, but they are really dark. (see attachment, it's 'Hand'.)

I'm not sure whether it's caused by wrong configurations, or hardware defect?

Here are information related to the camera.

[get_aero_version]

BIOS_VERSION = Aero-01.00.12_Prod

OS_VERSION = v01.00.04

AIRMAP_VERSION = 1.8

FPGA_VERSION = 0xff 0xff

Hi Leonardo,

Thanks for your support.

What do you get if you try those commands on your RTF?

It would be helpful to identify what's wrong with my RTF.

By the way, are there other tools or commands to gather camera, i2c bus information?

Bests,

Aki

Hi Leonardo,

I'm just wondering that you have got any updates from your team.

I have a quick question.

Could your team re-produce my issue? Or they work fine on their RTFs.

I'm still not sure whether this issue is caused due to my environment, or happens on any RTF. So if you can upload the result what you got on your RTF w/ those commands, it would be helpful to compare them to mine.

Bests,

Aki

How's going on the investigation, any updates?

It seems like harder to solve than I expected, doesn't it...

My original objective is just getting color video stream from front camera, OV8858. But as I mentioned, I couldn't get color image, instead I got dark image.

Do we have any other ways, instead of 'capture_example'? Tools, commands, or sample codes...

Thanks for your continuous support,

Aki

Hi Aki,

 

 

Unfortunately, we don't have updates, but I have to tell to you that we are doing our best to solve this.

 

 

At the moment, we don't have other ways to do this. We only have the capture_example.

 

 

We will contact you as soon as we have updates.

 

 

We appreciate your patience.

 

 

Regards,
