thanks for the answers

  Still unable to connect the camera... neither V4l2 nor uvc work.

[JamesF]

Hmmm.  Does the camera appear in the drop-down menu for UVC now, or just V4L2?

James

[bilbo-le-hobbit]

The camera appears for UVC and V4L2

[JamesF]

Well, that's a step forward, at least.  Have you installed the udev rules and rebooted or reloaded the udev daemon?

James

[bilbo-le-hobbit]

I've rebooted since then. No change. This is my rules.d list :

[JamesF]

Are you running the application from the command line, and if so does it produce any output in the terminal window?

James

[bilbo-le-hobbit]

It is rather laconic...

eric@MIRPHAK:~$ oacaptureopen of UVC device failed

How to start oacapture in a verbose mode (if it's possible) ?

[JamesF]

Hmmm.  That means the failure is in the uvc library, which is a bit more tricky.  Is it possible for me to get access to the machine?

[bilbo-le-hobbit]

It is possible, but how can I do ?

[JamesF]

It is possible, but how can I do ?

I'll leave that for a moment I think.  First I'll try to build a version with debugging enabled in the UVC library.  That might shed some light on what is happening.

I've had another idea

What do you get when you run the "id" command?

James

[JamesF]

Looks like Apple have been significantly messing about with the USB subsystem in El Capitan and what has worked ever since Snow Leopard is now broken   I'm still trying to work out why.

No problem.  Can you add yourself to the "users" group and try again?  You'll need to log out and log in again for the change to take effect.

Ok, done:

[JamesF]

Now can the UVC driver open the camera correctly?

James

[bilbo-le-hobbit]

Yes ! Camera connected ! But no colors for now. It also doesn't work with fps = 12, only with 7,5 and 3,5 fps

Well, that's progress

I'd guess that to get colour you may need to change enable demosaic in the "options" menu and then possibly try each of the mosaic format options in the "settings" menu to find the one that works.

James

[bilbo-le-hobbit]

Thunderbirds are go !

Well done, Brains !

[JamesF]

Excellent

I'm not sure about the 12fps issue at the moment.  As far as I recall these cameras do restrict the frame rate if they can't negotiate enough bandwidth on the USB bus to deliver frames of the requested size at the requested rate.  I have no idea if that is the problem here though.

Hi James,

First, thanks for the great work to get the ASI cameras to work on linux. I am building an all-sky set up with an ASI224 and a Raspberry Pi. Version 0.8.0 works great but I was wondering if there was a command line version of the application. My plan was to start oaCapture with a cron task so I could start capturing images without the need for clicking on the gui. That would also let the system restart by itself upon power failures (which happens fairly often up here).

Sorry if this subject has been mentioned elsewhere already but I thought I would ask since you talked about it when you released version 0.2.0.

Thanks

Thomas
