Projector / Open Broadcaster Software / OBS Studio

HDMI SWITCH (3 IN 1 OUT)

Press the SELECT button to switch between…

  1. The Slideshow (which is generated by the small black Raspberry Pi box on top of the SWITCH)
  2. The Pulpit HDMI port on the step near the pulpit (for the ELMO camera, or the speaker’s laptop for a Powerpoint)
  3. The loose HDMI cable in the sound cabinet, to which a laptop or Chromebook may be connected for YouTube videos.

 

WINDOWS DESKTOP ICONS for OBS Studio and PROJECTOR

NEC PROJECTOR LAN CONTROL "REMOTE DASHBOARD"

The desktop icon is a Chrome Browser shortcut to the static IP address of the projector (http://192.168.1.135)  which displays the Projector LAN Control. Note that no software is necessary.

  1. POWER ON/OFF buttons. Note that if you power off a warm projector, it will not restart for a few minutes until the bulb has cooled down.
  2. SOURCE SELECT:  
    • Click HDMI to project whichever HDMI device is selected on the HDMI SWITCH BOX or…  
    • Click NETWORK to temporarily "mute" the projection (makes the projector go dark, but keeps running).
    • You’ll use "NETWORK" if you expect to use the projector again shortly after the slideshow.
    • Just simply power OFF the projector if you do NOT expect to use the projector again after the slideshow.
  3. Don’t use these VOLUME / AV MUTE buttons. Instead, control the volume with the mixing board and mute or unmute projection by clicking the HDMI or NETWORK buttons as described in #2.
  4. PROJECTOR STATUS provides statistics about the projector’s use and bulb life.

 

PROJECTOR AUDIO VOLUME (use the MIXING BOARD SLIDER)

Use the "PROJECTOR" slider on the Mixing Board to control the audio volume of any video being projected. Note that you will not use the volume buttons on the browser dashboard.

Technical Info: Audio is extracted from the HDMI switchbox and patched into a channel on the mixing board.  That’s why you’ll use a physical mixing board slider instead of the volume controls on screen..   Use the "PROJECTOR" slider on the mixing board to send pHDMI cables transmit both video and sound, so if a presenter is using sound on a computer at the pulpit, or a youTube video is showing on the Chromebook in the audio cabinet, the sound is automatically controlled by the "Projector" slider and sent through the meeting house speakers.

 

OPERATING OBS / Open Broadcaster Software

OBS automatically starts with all the previous settings.  

  1. LIVE VIDEO (PREVIEW).  Right click on the top section of the screen to display the Preview dialog, then select Fullscreen Projector (Preview) > Display 1 to sends live video to other video screens in the building (Display 1 is the HDMI out from the computer that goes through an HDMI splitter to other TV’s in the building).
  2. SCENE: Click any row in the SCENE section to select a predefined view from the a camera
  3. MIC/AUX: Use the slider (see arrow) to make sure the volume is adequate for the other TV’s and YouTube stream.
  4. START STREAMING / START RECORDING –  You need only click "START STREAMING".  Recording to disk occurs automatically because of this setting: "File > Settings > General > Output > Automatically record when streaming"
  5. PAN & ZOOM: CLICK AND DRAG, anywhere to repositon the scene.  Note that you can drag the view to display a corner, then click and drag any corner to resize (ZOOM) the scene.
  6. STREAMING STATISTICS are displayed at the lower right corner of the screen

 

View > Multiview (Windowed) (OPTIONAL)

I don’t find any value in displaying this Multiview Preview since the "SCENES" already have well defined titles.  But here’s how to display the Multiview, if you want to use it.

The "Stream Key" is provided to you by YouTube when setting up a YouTube Creator account.
