Have you asked Ctronics what format their files are in? Do they have a program for converting to conventional files?

The source file has the extension 265 which makes me think, that it's only the x265 video part.

That is possible, but then there should be a matching file for the audio.

Different security cameras do wildly different things. A lot of them require special plug-ins to use with browsers.

Correct, it's an HEVC elementary stream (as per the scan log). The audio must be another file elsewhere.

To Woodstock: Good thought. Yes, Ctronics has a converter (of sorts) but converted files seem to behave the same.
