How to Share Screen Audio on Jitsi Meet with Mac Using BlackHole

-

Jitsi Meet is the open-source alternative to Zoom. Jitsi Meet is free and does not have the 40-minute limit that Zoom imposes. There is also nothing to download and install, except for the mobile version.

It works almost like Zoom except there is one problem. There is no audio from the screen share.

I want to use Jitsi Meet to share my video editing experience via online classes, so audio is critical.

On 7 April 2020, Jitsi added the ability to share system audio together with the screen!

WAIT! You can share the entire system audio ONLY on Windows…

“On Windows, you are able to share the entire system audio, but on Linux and macOS just that of the tab you’re sharing.”… https://jitsi.org/blog/features-update-april-2020/

On a Mac, I can only share audio coming from one single Google Chrome tab.

Sorry… It’s the same problem with Windows too… https://community.jitsi.org/t/screen-sharing-share-audio-with-application-window/33484

So how? My video editing software does not operate from a Chrome tab.

Then I read about Blackhole for Mac by Existential Audio… https://www.gearnews.com/blackhole-is-a-free-soundflower-replacement-for-current-mac-users/

Blackhole is a Mac software that works by bringing the system audio (such as web browser and multimedia) to wherever you want for recording and processing.

After installing, set up Blackhole as an input and output device in the Audio MIDI Setup or in the Digital Audio Workstation.

Download Blackhole from here… https://github.com/ExistentialAudio/BlackHole

Definition from the Developer: “BlackHole is a modern macOS virtual audio driver that allows applications to pass audio to other applications with zero additional latency.”

Lets’s try it.

Installing BlackHole

  1. Download Installer… http://existential.audio/blackhole/ The installer is sent via email after providing a name and email address.
  2. Close all running audio applications… I just closed everything that plays audio, including YouTube I guess.
  3. Open and install package… follow the very clear installation instructions.

Setting up BlackHole

  • Open Audio Midi Setup app.
  • Setup Multi-output Device…
  • Set up Aggregate Device.
  • Open Sound System Preferences
  • Set Multi-Output as System Output Device
  • Set Jitsi microphone to BlackHole 16ch (Virtual)

Testing Jitsi with Blackhole

I can now stream my computer system sound through Jitsi… BUT BUT BUT…

I cannot stream both my microphone and system audio together.

The research continues…

PS:

Windows user? BlackHole for Windows is not ready yet. Here are some similar Virtual audio drivers compatible with Windows including JACK and LoopBeAudio... info thanks to https://www.musictech.net/news/blackhole-audio-routing/

Macbook Air M1 Case

I bought a transparent case for my MacBook Air M1 . It came with a free screen protector, a keyboard cover, and some rubber plugs to cover the ports. Check it out! https://youtu.be/d-wALSd3nn8 I didn't expect the rubber plugs. It was a nice surprise. The case fits snuggly, with access to all the ports. The keyboard cover is almost invisible to the eye. I have no intention to use the screen protector. Why? I need to see the true color of the display for my YouTube videos. ~ Adrian Lee  @Adrian Video Image  The video was recorded on iPhone 12 Pro Max with Filmic Pro app in 4K 60fps and edited with Capcut.

Sony Vegas Pro 8 makes it easier to edit videos from different cameras right from the timeline. You can capture and edit video for a single scene from 2 or more cameras or for a single scene shot a few times with one camera. Here is a tutorial of a Multicamera Edit of a drama I shot. The drama was acted out four times to the public and being a non-profit organization, the client have budget only for one videographer. For each of the 4 acts, the camcorder (Sony HDR-FX7 High Definition Camcorder) was placed at 4 different positions and shot in various angles. Multicamera edit is accomplished in only 8 steps with the Sony Vegas Pro 8. Step #1: Capture Multicamera Video Clips Use the normal Sony Vegas Video Capture function to capture recordings from each camera. Give each capture filename a unique name. Enable scene detection before capturing so that each segment is captured as a separate clip. Step #2 : Layout Video Clips on Timeline Drag and drop video clips over each other on the...
