Anyone managed to get the Caspa 4k camera working in Ref-os-iot?

Has anyone got the caspa 4k camera working with decent results? I can't get more than 15fps in 4k even with the thermal clamp raised, using vaapih265enc just results in blocky corrupted video, but mainly the autofocus is totally and utterly hopeless, and I can't find any way of turning it off. There are lots of icamerasrc settings for exposure, gain, balance etc, but nothing as far as I can see to control the autofocus (which is a separate i2c device?).

Hello fnoop,

 

 

Thanks for reaching out!

 

 

Unfortunately, we don't have access to this camera, so I can't reproduce the issue to compare my results. Gumstix ( https://store.gumstix.com/cameras-displays-gps/caspa-4k.html) does mention that the camera should be able to capture 4K video at 30 fps. So, the behavior you are explaining is not the expected.

 

 

Since Gumstix are the developers of this camera, they own the support of the camera. They do mention that the camera is compatible with Joule, so, I'd suggest you to try contacting them ( https://www.gumstix.com/support/) in order to see if this is normal behavior or if this can be improved. Hopefully they can provide you a more accurate support for this camera in specific.

 

 

I hope this information helps you,

Sorry Pedro, say what?

These cameras were announced by Intel:

And they are very clearly officially supported hardware, specifically for the Joule. Intel has written and published all of the software support for them :

The Intel documentation has lots of information about the sensor, but nothing that I can find about the lens. It's the lens that is the problem - the autofocus is very poor and we clearly need the ability to control it manually, or at least lock it to infinity. Otherwise it's pretty much useless.

I understand, let me try to find information about the lens. I'll get back to you as soon as I have any useful updates.

Hi fnoop,

 

 

Could you please let us know the commands you used when testing the camera? Do you get any error messages at any point?

 

 

Also, do you think this could be a power limit issue? If so, perhaps this guide can be of help: https://software.intel.com/en-us/node/721471.

Hi Pedro, I appreciate you trying to help but these questions aren't correct. I'm wanting to know if we can control the autofocus in any way?

Thanks

Hello fnoop,

 

 

Sorry for the delay in my response.

 

 

We have been informed that unfortunately, there are no user configurable elements of the auto-focus service, it cannot be turned off nor adjusted.
