We will now break down the first column of the live streaming workflow. This section will go over OBS, Loopback, and Webex tips and tricks for the host and also tools that panelists can use for virtual backgrounds.<\/p>\n

1. User 1 \u2014 Host: install OBS, loopback; Webex tips & tricks<\/strong><\/h3>\n

You can refer User 1 as part of the studio crew or the video producer. They have three main tasks. They are to run OBS, Loopback, and manage the Webex panelists. The Webex host won\u2019t participate in the video feed. This user will only manage the panelists, push users in and out of the Lobby, remove the floating icons, mute users, and pin the main video users in the grid view. Below is a short list of things the Host has to do.<\/p>\n

Install OBS
\n<\/strong>To minimize Murphy\u2019s law, make User 1, the dedicated machine to run OBS or\u00a0
\nOpen Broadcaster Software<\/em>
\n<\/a>.\u00a0<\/em>User 1 will have a dedicated laptop to stream to the various platforms like YouTube. This must be a very high-end device as it will be streaming 1080p, which can max out its x264 encoder or GPU. Without a good laptop or machine, there can be a huge impact on the system, causing the framerates of your video to suffer and making the whole experience unenjoyable for the viewer. This software will provide the Grid View, or some would like to say Hollywood Squares or the Brady Bunch view. Basically, OBS is your desktop screen capture application that will send a stream out to your platform of choice. The Broadcast Software section will go over the setup process of OBS.<\/p>\n

Install Loopback<\/strong>
\nNext, install\u00a0Loopback<\/a>\u00a0from Rogue Amoeba. This is not a free application and it is a Mac app that reroutes audio from one piece of hardware or software to another. It\u2019s best to think of it as a software pipe that pretends it has a hardware device on each end: audio input on one and audio output on the other. This application will be used to reroute audio from Webex to OBS. I also use this to also stream Spotify into the meeting and use my Cisco Headset 730 to monitor the session. We will go over the setup of this in the next section. Remarque : There\u2019s a lot of other free virtual audio drivers out there, and for non-Mac users, you can use\u00a0VB Cable<\/a>\u00a0or\u00a0Virtual Audio Cable<\/a>.<\/p>\n

Webex Tips & Tricks
\n<\/strong>There are a lot of things to think about now that you are a broadcaster. A few things to be aware of:
\nCPU –\u00a0<\/strong>Shut down unnecessary applications as OBS will consume a lot of CPU resources especially if you don\u2019t have a dedicated GPU on your machine. It\u2019s best to use devices with an NVENC H.264 New (GPU Encoding for Nvidia Graphics Cards) or an AMD H.264 (GPU Encoding for AMD GPUs).
\nLAN –\u00a0<\/strong>Avoid WiFi. Hardwire if necessary as this is a live stream.
\nDisable VPN\u00a0<\/strong>– You want to remove as much latency as possible.<\/p>\n

Improve and control your meeting experience.\u00a0<\/strong>Follow these steps to set up your stream. Here, you want to\u00a0Mute users joining<\/em>\u00a0your meeting and\u00a0disable sharing<\/em>\u00a0in the event someone accidentally shares their desktop. Once you have your Webex Meeting desktop application open, proceed with these settings.<\/p>\n

\u00c9tape 1\u00a0:<\/em>\u00a0Go to\u00a0
\nParticipant\u00a0<\/em>->\u00a0Mute on Entry<\/em><\/strong>\u00a0and enable it and also de-select \u201c
\nAnyone Can Share.<\/em>
\n<\/strong>\u00bb<\/p>\n

\n
\n
\n
\n

<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Enable Mute on Entry & Uncheck Anyone Can Share.<\/span><\/h5>\n

\u00c9tape 2\u00a0:<\/em>\u00a0Go to\u00a0
\nView<\/em>\u00a0->\u00a0Show or Hide Meeting Controls<\/em><\/strong>. You want to enable this. In the following picture, you\u2019ll see the meeting controls. You want to hide that during your broadcast.<\/p>\n

\n
\n
\n
\n

<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Uncheck to Hide the Meetings Controls.<\/span><\/h5>\n

\u00c9tape 2\u00a0:\u00a0<\/em>Understand the Host Lobby feature.\u00a0<\/strong>Here as you can have speakers rotate in and out of your call and you can control who is showing up on the video grid by pushing them into the Lobby.<\/p>\n

\n
\n
\n
\n

<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Waiting in the Lobby function.<\/span><\/h5>\n

You can also move people into the lobby once they are done speaking by right-clicking on the participant name.<\/p>\n

\n
\n
\n
\n

<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Move to the Lobby feature.<\/span><\/h5>\n

\u00c9tape 2.\u00a0Leave the Host \u201cUn-muted\u201d<\/strong> in Webex. If you do not, then no audio will pass through OBS and to the other panelists. Also, you don\u2019t have to worry about any noise being picked up as the physical microphone is not connected to the virtual driver.<\/p>\n

\n
\n
\n
\n

<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Unmute & Lock this thumbnail setting.<\/span><\/h5>\n

\u00c9tape 2. As you hover your mouse over the participant, you can select \u201c
\nLock this thumbnail video on a specific participant<\/em>
\n<\/strong>.\u201d This option can lock the video focus of the main video on a specific participant, or the active speaker. Si vous \u00eates l’organisateur, vous pouvez d\u00e9terminer la vid\u00e9o qui sera affich\u00e9e pour vous et vos participants.<\/p>\n

TIP:<\/em>\u00a0If you will be moving people in and out constantly or doing any of the above, then the Host privilege should be passed to another participant and you would leave Webex in full window mode for the OBS setup.<\/p>\n

2. User 2+ \u2014 Panelists and virtual background<\/h3>\n

For your other users speaking on the live stream, the best hardware to use is a dedicated video device. I prefer using a\u00a0Webex Room USB\u00a0or what I\u2019m using is a\u00a0Webex Desk Pro<\/a>\u00a0as my dedicated SIP endpoint. It\u2019s a 4K display that has a 12 MP HD camera, 71-degree field of view, 8 element microphone array with audio fencing with low audio latency, auto-framing, auto-focus, 3.1 directional speaker array, and overall fewer points of failures since I don\u2019t need other external devices like hardware switchers, encoders, O\/S and other applications running in the background found on a PC. Basically, think of the Desk Pro and Room USB device as a high-end dedicated webcam with a ton of advanced features. If you are using a laptop, make sure you have a headset. I have a\u00a0Cisco Headset 730<\/a>. It is boom less design coupled with adaptive noise cancellation and background noise reduction. If you don\u2019t have a nice high-end headset, then a regular mobile headset can work very well too.<\/p>\n

Virtual Backgrounds, Chroma Key:\u00a0<\/strong>For your panelists’ that do not have access to a premium video conference unit, then a basic webcam or DSLR would work as well. With the USB functionality, you can use OBS Chroma Key, Manycam, or Snapchat\u2019s\u00a0Snap Camera<\/a> to provide virtual backgrounds. These are some of the many applications that are out there, but this article won\u2019t go into a deep dive into this.<\/p>\n

Webex Desk Pro with Virtual Backgrounds.<\/span><\/h5>\n

TIP:<\/em>\u00a0Note that when you\u2019re live streaming using a software encoder, you\u2019re already putting the computer\u2019s CPU at additional load. Most virtual background software apps require extremely beefy CPUs like a quad-core 4th-gen Core i7 or 3GHz processors with 8 cores or more. In this article, I have my\u00a0Cisco Webex Desk Pro<\/a>\u00a0with the built-in background filters for my stream. It won\u2019t consume any CPU cycles on my laptop since all the work is done on the endpoints NVidia GPU chipset.<\/p>\n

Manycam<\/h3>\n

Manycam is a live-streaming service and a program that allows users to use their webcam with multiple different video conferencing applications and video streaming applications simultaneously for Windows and Mac computers. In this article, I will just focus on the virtual background setup.<\/p>\n

REMARQUE\u00a0:<\/em>\u00a0<\/strong>With one of the latest Webex Desktop updates, a new \u201chardened\u201d security compilation method on OS X was put in place so that only libraries that are signed by Cisco or Apple are loaded. This applies not only to Manycam but other third-party applications such as CamTwist, Ecamm, CameraLive, EpocCam, Snap Camera, etc. Since they are from third parties, the Webex Desktop app (for Meetings and Events) will not allow them to load.
\nThe way to bypass this is to use the browser version for Webex Meetings.<\/strong>
\n<\/em><\/p>\n

\u00c9tape 1\u00a0: Open Manycam and go to\u00a0Presets\u00a0<\/strong>and\u00a0Add a Video Source -> Webcam<\/strong>
\nStep 2: Go to\u00a0Chroma Key ->\u00a0<\/strong>(Toggle On)\u00a0Virtual Background -> Blur<\/strong>\u00a0or\u00a0Replac<\/strong>e to select your background in the drop-down window.<\/p>\n<\/div>\n<\/div>\n

\u00c9tape 2\u00a0: Open your browser. Since I\u2019m using chrome, so go to the toolbar and enter ->\u00a0chrome:\/\/settings\/content\/camera\u00a0<\/strong>and select\u00a0ManyCam Virtual Webcam<\/strong><\/p>\n
