This is just for debugging purposes. Simply set it in your terminal
and check if you see more plugins in the output.

That was me :)

The documentation specifically says "wraps v4l2src". "v4l2" stands for
"video4linux2": https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FVideo4Linux&data=04%7C01%7C%7Cb76cb32325084e761a7108da21e500b7%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637859564683470737%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=GdHFFQv0a5rdSoSbMW7Dni5u7wChupiaNxWKWaFPjPs%3D&reserved=0

When in doubt, look at the code:
