hi, i just bought my new camera zwo asi 120MM. I plugged, she's recognized. But when i want in indi control panel use the streaming i've the error below :

2016-05-20T18:57:32: Error reading video data (11)

I cannot neither use in the guiding module.

I use the last indi driver, kstars/ekos on kubuntu 16.04.

Thank you for your help.

Try this - go to Control tab of ZWO CCD 120MM device, enable Bandwidth for Set Auto property, retry streaming, let us know of the results.

hi,

thank for you response.

I tried to set auto, or not, the bandwidth, change her value, i receive a black screen and the button a the left stay yellow !
I tried with oacapture and i don't receive anymore video. But, i tried to a other (old) computer with a kubuntu 15.10 with oacapture and is work correctly.
I've afraid that is my kubuntu version (16.04) on this computer (a laptop intel core i3 with 6mo ram) have a problem...

Maybe a problem of permission ?

Thank for your help.

Christian

It works fine here, can you do a regular capture?

Hi Jasem,

what do you mean for regular capture ?

I,ve a strange behavior when i use the camera like ccd (and not in guide mode), when i want take a capture of 1 second, the counter of the time loop (from 1.0, 0.75 and 0.25 second) and doesn't stop. I must stop the capture manually.

Thank you.
Christian

It happened to me once that the counter never reached 0. Make sure that two instances of the driver are not running in the background.

Yes, i do a ps before to control that anymore indi drivers run in background.

fortunately, i have my old computer but my raspberry do me a misery...

that is not the stairway to heaven ...

Christian,
I've plugged my ASI 120MM in to my Dell Inspiron 1525 and can use it as a CCD cam together with the telescope simulator. On the other hand, streaming never worked for this cam whatever parameters I set. Clicking on the streaming button opens a blank window that vanishes after some seconds and the the error message is this blabla (11).

From the dmsg output I suspect that you used a USB3 port for the camera. That should not be a problem but you never know. If the machine offers an USB2 than use this and try again.

But !!! This was true until I updated to the recent indi/kstars stuff some minutes ago. Now I get
KStars detected INDI driver indi_asi_ccd crashed.
Now its broken.

Hi Klaus,
is exactly what happened ! but the ccd isn't on usb3 (i've look in KInfoCenter). I've had a similar problem with my raspberry. Impossible to start indi_asi_ccd, simulator, nothing ! I have completely reinstalled and now it's work fine.

maybe, reload all indi and driver from the svn repository, compile et install.

Christian

Hi Christian,

I always get the updates from Yasem's PPA and from other postings I can see that there are issues with other drivers too. Perhaps Yasem has an advice?

Klaus

Klaus,

Jasem, the magician, had always the response
