Preview video using Spinview, Spinnaker FLIRs etc.

[mdmornin]

Hello,
I am using the above workflow to collect electrophysiology data. Everything is working great, I was just hoping to enhance some of the functionality to include a preview of the video stream.
When I previously used a webcamera I was able to preview the video stream, however using FLIRs I do not see that option on the image node or elsewhere. I have searched on the various related nodes as well as searched through this GitHub and have not found anything specific to this yet. Am I missing something obvious or is there currently no way to preview Spinnaker / Teledyne FLIR videos through Bonsai?

The visualizer should be available to the Image operator. Otherwise, you might not have the Video.Design package installed.

Hi Bruno,
I was only able to test this this morning and while the option appears now it unfortunately crashes Bonsai when selected.

I am currently getting the above error message along with a crash when attempting to preview the videos

edit: here is the text as well

Additionally, after installing a community OpenTK package via Bonsai I now receive the following message:

Can you share the workflow file you are trying to use? thanks

Attached above. Let me know if any other information would be helpful. Is there a way to export a list of the packages a Bonsai environment has installed?
The only weird thing about the PC I am currently using is that it is setup to use OE's ONIX and therefore is in a Windows Test Mode on Build 19041. The errors feel like a Visual Studio or some other C+/C# manager issue, but I am pretty new to those development environments.

Can you also send your bonsai.config file? https://bonsai-rx.org/docs/articles/environments.html

[mdmornin]

I will be away from this computer for a bit, but I will send the config as soon as I get back next Friday.

Here is the config file. Apologies for the delay!

I am running into the same problem. Everything has been fine until the CrowdStrike outage happened. After I fixed that, Bonsai ran into this problem. Has a fix been found for this?

[mdmornin]

I have not found a fix yet. Please let me know if you do!

[hanwen-zhang-7]

Completing the interrupted update fixed the problem for me. Hope you find a fix soon!

I have an AMD Radeon installed, and did not realize it was missing drivers. I was able to fix this by installing a graphics driver via AMD's automated installer.
