Change Active Capture Card via JSON API

[andyhibbard]

I want to capture the video from multiple devices via multiple capture cards. I do not want to place a physical HDMI switch between a single capture card and the splitters of each device. I have a LG TV with webOS, which has an API I can use to determine the input device is currently showing on the TV. In theory, this should eliminate the need for a physical HDMI switch if I could change the active capture card HyperHDR is currently using. However, I cannot find any documentation on an API endpoint that can do this in the wiki or the JSON API wizard on the web UI. Does an API endpoint for this exist? Is there another way to alter this setting programmatically? The only way I have found to select the video card is via the web UI.

Currently running a fresh install of v21.0.0.0
