Hi Randy and welcome.. Hopefully you will find what your looking for.
I had to look up a old post to find the easycap instructions. (Thx for pointing this out)
The latest rasbian may also work, i haven't tested this setup for a long time.
Copy/pasted from my old post:
First of all, much information in this articel is retrived from this site
You need to have specific version of Raspbian in order to install and use video grabbers. For Easycap stk1160 the one from September’13 "raspbian-2013-09-16/". Download it and dump to sd card.
Easycap usb grabber comes with (at least) 4 different chipsets – You can check there how to distinguish one version from another based on lsusb output.
Im using STK1160 which is working out of the box.
If you get /dev/video0 you should be good to go. If not, verify correct chipset e.g
To be able to connect Gopro camera you need something like this , which im using.
