The effect of Slow Internet - Drone Pages
A video gallery will require a fast and unlimited data connection to be viable.
The same can be said if you wish to run a webserver, especially if you want to use it to distribute drone footage.
An example
I uploaded one of my drone videos as a test. To develop a proper video gallery I would need to do more work.
Flying to Munt Cottage
The example uses the HTML video tag.
Accesses on the weberver
It is interesting to see how the video tag accesses my webserver:
I held off the development and investigation on this subject until I had an unlimited fibre connection. The "hit" on the server is considerable but the limiting factor, with respect to buffering, is the speed of my webserver.
