Source Mirror doesn't load video from Video Capture Device

[pcgeek86]

Synopsis
In OBS, I have two separate sources:

1. A "raw" source of type Video Capture Device, which points to my Elgato Cam Link 4k
2. Source Mirror - points to Video Capture Device, and adds a couple video filters (ie. Chroma Key)

I have OBS configured this way, so that I can ingest the video from the Cam Link once, and then customize it based on each scene's unique needs, using separate Source Mirror instances.

When I launch OBS, the Source Mirror does not show my video from the Cam Link. I have to open the Properties page of the Source Mirror in order for it to initialize and load the video from the Video Capture Device.

This seems like a bug to me in the Source Mirror source type. Has anyone else, who's using the Source Mirror with a Video Capture Device, seen this behavior?

System Details

• Windows 10 Dev Insiders Preview Build 21387
• AMD Ryzen 9 3900x
• NVIDIA GeForce RTX 2080
• OBS version 27.0.1

I realized that I was running an older version of StreamFX. I just updated StreamFX to version 0.10.1. I also updated my NVIDIA Graphics Driver to the latest version. I'll keep an eye on this and see if it's still an issue after these updates.
