VLC is unique in its support for every codec under the sun. If it refuses to play a video file, it's probably because it's damaged beyond recovery, or not a video file at all. The default Windows and smartphone video players choke on all kinds of files, so you can't really expect that any given file is supported.

Last I checked the recommended method to play h.265 files in VLC was to re-encode them.
Realtime 265 decoding requires hardware support. There's not much they can be done by software it your driver/OS/graphics card combination cannot support that.
