VLC doesn't play video with Dokan

Question

I'm using dokany version of Dokan, to mount a disk on the system.

I've managed to implement all the necessary callbacks for the OS to be able to work with the dokan disk's files and folders.

Whenever I try to play a video file from the dokan disk with Media Player Classic, everything works great. When I try playing it with VLC, I get the following error:

File reading failed:
VLC could not read the file (Bad file descriptor).

UPDATE:

File reading failed:
VLC could not read the file (Bad file descriptor).
VLC can't recognize the input's format:
The format of 'file:///K:/%5BHorribleSubs%5D%20Fate%20Stay%20Night%20-%20Unlimited%20Blade%20Works%20-%2025%20%5B720p%5D.mkv' cannot be detected. Have a look at the log for details.

And when I read VLC's debug data, I get the following messages:

Answer 1

The solution was to update DokanNet to its latest version.

The video works fluently now!
