Tagging Video Frames with GPS Coordinates

Aside from using a hardware video encoding/decoding device, is there an easy wa开发者_运维问答s to capture frames from streaming videos and tag each frame with the current GPS coordinates?

Assume I am using windows, and I have the GPS coordinates sent in via USB and the camera is hooked up also. Any api or framework available for this?

Use DirectShow to grab the frames - there are many examples available like this CodeGuru post.
