Overview
Bino is a video player with a focus on 3D and Virtual Reality:
• Support for stereoscopic 3D videos in various formats
• Support for 360° and 180° videos, with and without stereoscopic 3D
• Support for Virtual Reality environments, including SteamVR, CAVEs, powerwalls, and
other multi-display / multi-GPU / multi-host systems

Scripting
Bino can read commands from a script file and execute them via the option --read-commands
scriptfile. This works both in GUI mode and in Virtual Reality mode.
The script file can also be a named pipe so that you can have arbitraty remote control
interfaces write commands into it as they come in.
Empty lines and comment lines (which begin with #) are ignored. The following commands
are supported:
• open [--input mode] [--surround mode] [--video-track vt] [--audio-track at] [--subtitle-
track st] URL
Open the URL and start playing. The options have the same meaning as the corresponding
command line options.
• capture [--audio-input ai] [--video-input vi]
Start capturing camera and microphone. The options have the same meaning as the
corresponding command line options.
• play
Start playing.
• pause
Pause.
• toggle-pause
Switch between pause and play.
• stop
Stop playing.
• playlist-next
Switch to next playlist entry.
• playlist-prev
Switch to previous playlist entry.
• playlist-loop mode
Set loop mode (off, one, all).
• quit
Quit Bino.
• set-position p
Set the video position to p, where p=0 is the beginning and p=1 is the end.
• seek seconds
Seek the given amounts of seconds forward or, if the number of seconds is negative,
backwards.
• wait stop|seconds
Wait until the video stops, or wait for the given number of seconds, before executing
the next command.
• set-mute on|off
Set the volume mute status.
• toggle-mute
Switch between mute and unmute.
• set-volume vol
Set the volume level to vol (between 0 and 1).
• adjust-volume offset
Adjust the volume by the given amount (the final volume is clamped between 0 and 1).
• set-output-mode mode
Set the given output mode. See the command line option --output for a list of modes.
• set-swap-eyes on|off
Set left/right eye swap.
• toggle-swap-eyes
Toggle left/right eye swap.
• set-fullscreen on|off
Set fullscreen mode.
• toggle-fullscreen
Toggle fullscreen mode.
File Name Conventions
Bino currently cannot detect the stereoscopic layout or the surround video mode from
metadata because Qt does not provide that information. It therefore has to guess.
Bino recognizes the following hints at the last part of the file name, just before the
file name extension (.ext):
• *-tb.ext, *-ab.ext: Input mode top-bottom
• *-tbh.ext, *-abq.ext: Input mode top-bottom-half
• *-bt.ext, *-ba.ext: Input mode bottom-top
• *-bth.ext, *-baq.ext: Input mode bottom-top-half
• *-lr.ext: Input mode left-right
• *-lrh.ext, *-lrq.ext: Input mode left-right-half
• *-rl.ext: Input mode right-left
• *-rlh.ext, *-rlq.ext: Input mode right-left-half
• *-2d.ext: Input mode mono
Additionally, if the number 180 or 360 is part of the file name and separated by
neighboring digits or letters by other characters, then the corresponding surround mode is
assumed.
Virtual Reality
Bino supports all sorts of Virtual Reality environments via QVR (https://marlam.de/qvr):
• When QVR is compiled with just with Qt6, CAVEs and powerwalls and similar multi-display
setups are supported, including multi-GPU and multi-host rendering.
• When QVR is additionally compiled with VRPN (https://github.com/vrpn/vrpn), all sorts of
tracking and interaction hardware for such systems are supported.
• When QVR is additionally compiled with OpenVR (https://github.com/ValveSoftware/openvr),
SteamVR is supported and automatically detected (e.g. HTC Vive).
To start Bino in VR mode, use the option --vr. Bino will then display a screen in the
virtual world, and the video will be displayed on that screen, unless the input is a
surround video (360° or 180°), which will of course be displayed all around the viewer.
The default is a 16:9 screen in a few meters distance from the viewer, but you can use the
--vr-screen option to either define arbitrary planar screens via their bottom left, bottom
right and top left corners, or to load arbitrary screen geometry from an OBJ file. The
latter case is useful e.g. if you want Bino’s virtual screen to coincide with a curved
physical screen.
Bino uses QVRs default navigation, which may be based on autodetected controllers such as
the HTC Vive controllers, or on tracking and interaction hardware configured via QVR for
your VR system, or on the mouse and WASDQE keys if nothing else is available.
Additional interaction in VR mode is currently limited to the same keyboard shortcuts that
also work in GUI mode. That means you currently must specify the video to play on the
command line, and have no way to pause, skip or seek – this will be added in a future
version.
