Tip

Most functionality provided by this project has been integrated into spice2x with the -iidxtdjcamhook flag

If you just want to use your cameras in-game, please consider using spice2x instead. Some improvements over 2dxcamhook include persistent camera control for formats and options (e.g. Exposure, Focus, etc.) configurable via the in-game overlay, forwards compatibility with future game versions via pattern scanning, easy one-click horizontal and vertical flipping, and much more.

If you are unable to use spice2x, or need to capture from a virtual camera source, or a device with an esoteric non-UVC driver, or need the additional flexibility provided by OBS, you may need to use 2dxcamhook instead

2dxcamhook

Hook library for replacing in-game camera textures with Spout2 senders

Compatibility

  • beatmania IIDX 27 HEROIC VERSE
  • beatmania IIDX 28 BISTROVER
  • beatmania IIDX 29 CastHour
  • beatmania IIDX 30 RESIDENT
  • beatmania IIDX 31 EPOLIS

※ In-game cameras are not supported in the LDJ-003 version of IIDX 30

Configuration

Using OBS Studio

  • Install the Spout2 Plugin for OBS Studio
  • Right-click a Source or Scene in OBS Studio and select "Filters"
  • Press the add button under Effect Filters and select "Spout Filter"
  • Set the name to "Camera A" and press the "Change Spout Filter Name" button
  • Repeat the same steps for the second camera, using name "Camera B" instead

Note: The game expects the camera texture to be 1280x720 in size. If you have set OBS to output in a higher resolution, you should also add a "Scaling/Aspect Ratio" filter above the "Spout Filter" and set the resolution to 1280x720. It will appear incorrectly in the camera check menu, but will be normal when in-game.

Installation

  • Compile from source or download a pre-built version from the releases page
  • Copy the appropriate 2dxcamhook.dll build to your game directory
  • Alter your launch command to load the library during startup
