@Yar thank you.
@Tony That looks interesting. However, this project seems to be about the server side, which also is interesting - but the problems mentioned above don't seem to come from the server side.
This is about the remote control API, i.e. controlling what movie is playing "from the outside" (see https://deovr.com/doc#remote-control ). I want to switch movies available on my server without having to use the oculus controllers. But sending "New video path" to the oculus opens the videos in the wrong mode when directly specifying the mp4 file - and specifying the detailed json file with all the movie metadata just does nothing.
