Help! Howto pipe video to v4l2loopback

adnus

Hello everybody! I'm new here.
First of all, I'm not a programmer! So please don't answer with 'Hey, that's easy, just do it so and so' :-) I am a sysadmin with some linux knowledge. And here is my question:
How can I pipe a ZWO ASI videostream captured by the SDK to a v4l2loopback device?

And that's the background:

We have two ASI Cameras connected by USB to a Linux Mint:

jens@allsky-ZBOX-CI327NANO-GS-01:~/ASI_linux_mac_SDK_V1.29/demo/bin/x64$ ./test_gui2_snap attached cameras: 0 ZWO ASI174MM 1 ZWO ASI178MC
I managed to compile the demo code 'test_gui_video' without an error (jippi). The demo 'test_gui_snap' is not working anymore, since the opencv changed to opencv4. Some functions are nor more available, 'saveImage' and other.

However, the demo code 'test_gui_video' is working and produce data, I hope. Currently, the demo open a windows, what I cannot see as remote ssh user.

How can I save this video data

to a file
to a device such as v4l2loopback.

We wanna use an opensource software for meteor tracking. This software can only read a /dev/video device - or a rtsp-stream from an IP-Camera. I'd like to read the video stream from our monochrome camera and serve the stream for the meteor detechtion software.

adnus We currently have no plans to do this under Linux. If you just want to use an opensource software for meteor tracking, try our ASIStudio. We have a subroutine called ASIMeteotCap that can do that.
Look forward to your reply!

We wanna use the great Croation Meteor Network and its opensource RMS Software. Your ASIStudio is surely cool, including your ASIMeteorCap. But we need a headless solution. We don't want popup a windows on a Desktop PC. We wanna record meteors the whole night on a linux mini pc.
However, I found a solution and I have learned c++ in the last few days :-) . Our ASI174MM is streaming now to a video4linux device, and RMS is capture from this source.

Zzzz

adnus Great. Look forward to your achievement!

Sometimes I think that some or all of the answers here are from an AI, not from a ASI staff. Many answers don't make sense, and there's no relevance to the question. This is our future :-)

adnus Hi Adnus, I'm sorry for the bad experience you had. I understand your confusion. You would like to get an image with v4l2loopback format, but our SDK currently only provides images in RAW format. We currently have no plans to develop interfaces related to v4l2loopback. You want to save the image data as a file. fits is a common file format in astronomy. Cfitsio is an open source library. You can refer to: https://heasarc.gsfc.nasa.gov/fitsio/
