A virtual reality video player for Linux, based on Valve's openvr hellovr_opengl sample code: https://github.com/ValveSoftware/openvr/tree/master/samples
Displays as an overlay on top of other VR applications. Defaults to stereoscopic mode unless --flat is given.
Known Issues:
- No controls
- No output to the preview window
Might now work when using a compositor such as picom when using the glx backend (when capturing a window).
Run ./build.sh or if you are running Arch Linux, then you can find it on aur under the name vr-video-player-git (yay -S vr-video-player-git).
Dependencies needed when building using build.sh: glm, glew, sdl2, openvr, libx11, libxcomposite, libxfixes, libmpv.
vr-video-player has two options. Either capture a window and view it in vr (works only on x11) or a work-in-progress built-in mpv option.
To play a video with the built-in mpv player, run vr-video-player like so:
./vr-video-player --sphere --video <file-path>
for example:
./vr-video-player --sphere --video /home/adam/Videos/my-cool-vr-video.mp4
--sphere can be replaced with --flat, plane or --sphere360 for different display modes.
Install xdotool and launch a video in a video player (I recommend mpv, because browsers, smplayer and vlc player remove the vr for 360 videos) and resize it to fit your monitor or larger for best quality and then,
if you want to watch 180 degree stereoscopic videos then run:
./vr-video-player $(xdotool selectwindow)
and click on your video player.
if you want to watch side-by-side stereoscopic videos or games (flat) then run:
./vr-video-player --flat $(xdotool selectwindow)`
and click on your video player.
if the side-by-side video is mirrored so that the left side is on the right side of the video, then run:
./vr-video-player --flat --right-left $(xdotool selectwindow)
and click on your video player.
if you want to watch a regular non-stereoscopic video, then run:
./vr-video-player --plane $(xdotool selectwindow)
and click on your video player.
if you want to watch a 360 video (for example a youtube video), then run:
./vr-video-player --sphere360 $(xdotool selectwindow)
and click on your video player.
Alternatively, you can run:
./vr-video-player --follow-focused
and vr-video-player will automatically select the focused window (and update when the focused window changes).
The video might not be in front of you, so to move the video in front of you, you can do any of the following:
- Pull the trigger on the vr controller
- Press "Alt + F1"
- Press the "W" key while the vr-video-player is focused
- Press the select/back button on an xbox controller while the application is focused
- Send a SIGUSR1 signal to the application, using the following command:
killall -USR1 vr-video-player
You can zoom the view with Alt + Q/E.
When using the built-in video player and the vr window is focused you can then use left/right arrow keys to move back/forward in the video and space to pause. In the future vr-video-player will show a graphical interface inside vr to manipulate the video.
You can launch vr-video-player without any arguments to show a list of all arguments.
Note: If the cursor position is weird and does not match what you are seeing in stereoscopic vr mode, then try running the vr video player with the --cursor-wrap option:
--cursor-wrap and --no-cursor-wrap changes the behavior of the cursor in steroscopic mode. Usually in games the game view is mirrored but the cursor is not and the center of the game which is normally at the center moves to 1/4 and 3/4 of the window. With --cursor-wrap, the cursor position in VR will match the real position of the cursor relative to the window and with --no-cursor-wrap the cursor will match the position of the cursor as the game sees it.
Note: --cursor-scale is set to 0 by default in 180 degrees stereoscopic mode and 2 in other modes. Also --no-cursor-wrap is set by default in --flat mode.
Note: When fullscreening a video, the video player can add black bars to the top and bottom. If you do not want black blacks then you either have to view the video in windowed mode or try launching mpv with the --panscan=1.0 option.
This vr video player can also be used to play games in VR to to get a 3D effect, and even for games that don't support VR.
For games such as Trine that have built-in side-by-side view, you can launch it with proton and there is a launch option for side-by-side view. Select this and when the game launches, get the X11 window id of the game
and launch vr video player with the --flat option.
For games that do not have built-in side-by-side view, you can use ReShade (or vkBasalt for linux native games) and SuperDepth3D_VR.fx effect with proton. This will make the game render with side-by-side view and you can then get the X11 window id of the game and launch vr video player with the --flat option. The game you are playing might require settings to be changed manually in ReShade for SuperDepth3D_VR to make it look better.
SteamVR on linux has several issues. For example if you launch vr-video-player it may get stuck with a "Next up" window inside vr. If that is the case, then close SteamVR and make sure all SteamVR are dead (kill them if they aren't) and launch vr-video-player and it should launch SteamVR (this is different than launching the SteamVR application in steam).
