A legal friend of mine received a file from a colleague with a .g64 file extension that she needs to view. My searching indicates that the .64 file extension is some form of proprietary security video format but I can't determine the exact software.
I checked VLC but it doesn't look like there is any native support for it, and I couldn't find any addon codecs for it. Other references to download player software for it look like they are probably just click-bait scams.
Any ideas what I can use to play the video?
