Get image from MIPI camera OV7251 nad OV8858 local not stream #312

Closed Thanos254 closed 6 years ago

Thanos254 commented 6 years ago

Dear All, 

We are looking to get the image (stream ) from two MIPI cameras OV7251 (global shutter VGA) OV8858 (rolling shutter HD ) on Intel Aero board on local monitor that is connected with HDMI cable to the Aero board with gstreamer.  Please tell us how can we do this?  We are aware of 06 Cameras and Video · intel-aero/meta-intel-aero Wiki · GitHub  and we don't want to use streaming over WiFI.  We want to use command like this: gst-launch-1.0 v4l2src /dev/videox (video x is eg video1 ) ! autovideoconvert ! autovideosink  OR gst-launch-1.0 v4l2src /dev/videox ! format ! xvimagesink  How can we do this ??  We are using: 

BIOS_VERSION = Aero-01.00.13 OS_VERSION = Poky Aero (Intel Aero Linux Distro) 1.6.1 (pyro)" AIRMAP_VERSION = 1.8 FPGA_VERSION = 0xc2AeroFC firmware version = 1.6.5 

We noticed that there are some error in dmesg with OV7251.

 Please can you look at this?  Also please can you share the correct dmesg from your aero platform?

It is not possible to take images from the two cameras by running gst-pipeline in command line. Read here how you can do it - https://github.com/intel-aero/meta-intel-aero/wiki/06-Cameras-and-Video#take-a-photo-with-the-black-and-white-camera

thank you for the replay, we will try to capture the image from OV7251 as you suggested with the sample app.

Regarding the OV8858, ok there are some issues with underexposed picture.

But can you tell me where is the sample app for the HD OV8858 camera ?

Or can we get the stream ( doesn't mater if underexposed) with gstreamer from the OV8858?

Which device corresponds to the OV8858 camera?

Example of how get frames from ov8858 https://github.com/intel-aero/sample-apps/tree/master/hd-camera but the quality is not good at all, the driver needs some changes.
