Hi,

I am new owner of raspi 4 8G , installed with a SSD 120G as USB boot , i just installed Astroberry server , astroDMx, Rpi-Cam_Web_Interface, and meteotuxpi .
My goal is to use AstroDMX for my SVBony SV205 camera , and used the raspi-Cam V1 as guide scope camera.
On Oacapture i used the camera (V4L2) camera0, and i get an image ( FPS 4.23) with a camera ROI of 2592 X 1944 but when i am trying to get a capture , i got this error : unable to create file for output.
I am a beginner in astrophoto, i did research on this type of error and didn't find what is going on ....

Please indicate where to search if possible,
Regards,
P.S. Should you need more information , please let me know

Oacapture worked for me with a ZWO cc'd.

When I first tried to save video I got same error.

I set output to ser instead of Avi

And

I set the output directory to /home/astroberru

And it worked! Maybe default save directory is not writeable.

Must plug in the rpi am to see if I can get it to work.
