How can you add GPS location data to a Image

I am trying to combine GPS data and video. I have a GPS device which gives me gps/nmea format gps data. I am reading each frame from the video and storing it as a image and want to add GPSInfo (metadata) to it. If I use the IMWRITE function, it doesn't let me add the GPSInfo data since its not a tag which can be edited or changed.

How can I then geotag images using MATLAB?
