Is it possible to add a helicopter's video files to Google Earth or QGIS ? We have a flight path points derived from the xml file associated with the .mpg file which I envision being used to pilot the video. The .mpg files range in size 100mb to 2gb.
An action runs a command, that in your case will open a movie player in a separate window, not a window embedded in QGIS, when you click on a point.
Actions for a layer are set under Properties > Actions. Look at some of the default actions; There is a button for the default sample actions coming with QGIS.
You will need a column with the filepath to the video.
Check some of the many tutorial on the net for QGIS actions:
