ValueError: src.shape[0] must be equal or larger than 8.

I keep running into the following error and I'm not sure whats causing it. When I attempting a ransac calculation the following error pops up, and it's not consistent, sometime I can run the code without any errors whatsoever, sometime it's at different time stamps through the video the error will pop up. Any help will be appreciated!!!
