I don't recall Canon documenting the method to retreive shutter count in the Canon EOS SDK (I checked it once upon a time and didn't see it.). Mostly what photographers care about is the number of times the shutter had to open & close mechanically and in video mode it really opens once to expose the sensor and recording of video frames doesn't cause any mechanical movement of the shutter (the camera uses an electronic shutter in that mode instead of the mechanical focal plane shutter.) I'm not sure what Canon uses in their own count. It is accurate and only counts upward (if someone resets a camera the count is not reset to zero.) It does not use image EXIF data nor does it uses file numbering, etc. Dire Studio documents that their shutter count utility gives the count of "still" photos taken by the camera but does not include video (which makes sense).
