1. If I open try to use video in any app that supports it, the green light comes on, video never starts and after a few seconds the light goes off. I've tried anything I could find online.
killing vdcassistant
2. restarting
3. resetting smc
4. esnuring apps are not conflicting for camera use
5. checked system information to ensure the camera is connected
6. etc.
Should i assume it's a hardware issue at this point?
Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
To trouble shoot further you can:
Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test will take a little longer as caches get rebuilt.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443
This will tell you if it a universal issue or isolated to your user/admin account.
This will give you a good indication if it is hardware.
At that point— In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
Make an appointment for a "hardware issue"—
