About Vivoh
Vivoh is the leading provider of enterprise multicast video apps for all-hands meetings. Our customers include Financial Services, Energy, Government, and Technology companies that handle billions of network transactions every day. Vivoh protects their networks from the disruptive impact of live video. You can find us in the Zoom App Marketplace and the Webex App Hub or https://vivoh.com.

While many issues persist (such as broken audio) and significant work is needed to fully operationalize the service, we are excited to share this early preview with you.

Please contact erik@vivoh.com for more information and check here for updates.

The steps to upgrade are:

1. Download the latest server binary (currently 3.8.1.0, linked below)
2. Stop the running Vivoh Webinar Manager
3. Install the new binary.
4. Manually start the server and look at error messages to guide your upgrade process.
5. Once you have verified the server and configuration are upgraded correctly, start the server as a system service.

These steps are documented in detail here.

Download the latest server binary

The 3.8.1.0 binary (latest) can be found here https://releases.vivoh.com/binaries/vwm/2023_03/vivoh-webinar-manager__6b5fd029__3.8.1.0_amd64.deb

To download this file, login via SSH to your server and use wget https://releases.vivoh.com/binaries/vwm/2023_03/vivoh-webinar-manager__6b5fd029__3.8.1.0_amd64.deb

Stop the current Vivoh Webinar Manager service

systemctl stop vivoh-webinar-manager

Install the new Vivoh Webinar Manager package using the command dpkg -i ./vivoh-webinar-manager__6b5fd029__3.8.1.0_amd64.deb

You will see output like the following:

To start this service, use: systemctl start vivoh-webinar-manager

Notice the messages indicate it is installing over the existing Vivoh Webinar Manager service. It will not overwrite an existing configuration file if one already exists (found in /etc/vivoh/vwm/vwm.ini)

Start the Vivoh Webinar Manager manually

Often when upgrading there are new security requirements which require review of the configuration file. For example, older versions of the Vivoh Webinar Manager had less strict password requirements, but newer versions require a much safer password.

After installing, attempt to restart the service using systemctl start vivoh-webinar-manager and then check the status using systemctl status vivoh-webinar-manager

# systemctl status vivoh-webinar-manager

This indicates the server did not start correctly. To see why, run the Vivoh Webinar Manager manually with this command: /usr/local/vivoh/vivoh-webinar-manager -a /etc/vivoh/vwm/vwm.ini. (Please note, you must be in the root directory (`cd /`) so that the Vivoh Webinar Manager can locate the SQL database. This is only required when running manually.)

Vivoh Wallflower is a programmable, branded, interactive, enhanced gallery view for Zoom, which can be viewed as a Zoom participant and projected on a video wall.

Vivoh leveraged ZoomISO and Isadora, combined with their own event management software to rotate remote participants in a branded visual experience with emojis and transition effects. (The available chat function was not used for this event.) Wallflower automatically switched Zoom participants and the onsite producer was able to manually add and remove them, in real-time, via a mobile web interface.

As companies strive to enhance hybrid meeting experiences, Vivoh Wallflower brings remote and in-person participants together and keeps them highly engaged. Feedback from multiple on-site participants was positive regarding the impact of Vivoh Wallflower on the overall meeting experience.

About Vivoh
Vivoh is the leading provider of enterprise multicast video apps for all-hands meetings.

Simulcast uses WebRTC technology to deliver multiple resolutions, bitrates, and color depths - all captured, encoded, and encrypted at the point of production then distributed without transcoding to users based upon their adapting network capabilities.

This architecture delivers the highest quality live streaming broadcasts at scale with low latency and end-to-end encryption. Server-side transcoding unnecessarily decrypts your content, adds latency, and reduces quality.

Vivoh has added AV1 codec support and WebRTC streaming to their flagship Vivoh Media Player, used by FINRA and two Fortune 500 companies for their CEO Town Hall webcasts.

Vivoh has developed a method of capturing and streaming live 10-Bit Quad HD (2560 x 1440) video at 60 frames per second, plus two additional HD resolution streams, all on modern Intel or AMD based PCs. No additional hardware is needed for Vivoh real-time Simulcast processing.

Vivoh is committed to providing the most scalable and secure system to broadcast video across enterprise networks. Now it is more simple than ever.

Vivoh Broadcast is software that can be deployed on Linux, via Docker, or as an ESXi virtual appliance. Vivoh will also provide a turnkey appliance for rent!

Corporate communicators can easily produce live video streams of webinars or town hall meetings using affordable BlackMagic ATEM switchers, which will send high quality video to Vivoh Broadcast software for internal distribution and Webex/Zoom/Teams/Meet for external attendees. One click sends the stream to Vivoh Broadcast. No software configuration is required for each event!

Vivoh Broadcast enables automatic failover from multicast to unicast and from Vivoh to Webex/Zoom/Teams/Meet all from a single link that can be published to all users. Your network will be protected even as tens of thousands of internal viewers join an HD quality live broadcast.

Live video streams can saturate enterprise networks, which may cause office-wide connectivity to fail, poor video quality, loss of productivity, and user frustration.

Now Kaltura, Vimeo, Brightcove, YouTube, Cloudflare, and even Microsoft Teams Live Event streams can be scaled behind the enterprise firewall.

We are so happy to be able to meet with our customer and learn about how to make Vivoh OnTime even more valuable to them. We flew into Tokyo and then took the Shinkansen (bullet train) to Kanazawa and Kyoto. We especially loved the Imperial Garden and castle in Kanazawa.

Stay tuned for some new feature announcements soon!

Introducing the Vivoh eCDN!

Cloudflare Stream supports RTMPS ingest from Zoom, Webex, MS Teams, or most video encoders, including WireCast and OBS. Many video streaming services do the same. What is rare is that they allow you to pull RTMPS from their service while others only allow you to pull HLS/DASH or to push to another RTMP server.

This is why we are so excited about Cloudflare Stream. Vivoh customers can easily deploy our 100% on premises software which will pull RTMPS from Cloudflare Stream and generate a local multicast broadcast of the Zoom Webinar.

Vivoh provides a Webinar Manager server as part of this software which allows you to publish one link to your webinar. This will launch the Vivoh Multicast App if users are on a local multicast network or the Zoom App if not.

Soon Cloudflare Stream will support WebRTC playback from the same RTMPS input stream. Combine this with the Vivoh Webinar Manager and now users can be directed to either the Vivoh Multicast App or a low latency unicast stream from Cloudflare that will work well in the browser on the desktop or mobile phones.

All other streaming solutions either do not scale well across both external and internal networks or provide high latency live video which prevents the desired real-time audience engagement of a webinar.

Soon Cloudflare Stream with Vivoh Multicast Edge software will make webinar streaming both compelling and scalable for today's hybrid work environment.

Industry Trend Emerges
This move follows other Vivoh customers, including a Fortune 200 insurance company, a 40,000 person healthcare provider, and a leading financial services company, which started with Windows Media multicast. Vivoh offers the most secure and cost-effective method to reach thousands of internal employees with low latency video without disrupting internal networks.

Microsoft no longer offers Windows Media multicast which has left many companies searching for an alternative to support the requirement to reach thousands of employees who are onsite. Zoom and Webex work well for remote employees but will disrupt enterprise networks when many join from the office.

Some companies deployed Adobe Flash multicast technology only to find themselves without a supported player. Some had adopted a method which installs a local web server on every desktop that converts multicast video to unicast so that it can play in a browser. Many have abandoned multicast altogether.

We have strong opinions about how to move forward after Windows Media multicast. It should be simple, reliable, secure, and cost effective.

Enterprises deploy Zoom and Webex client software regularly to every desktop and our customers use the same method to deploy the Vivoh Multicast App.

Vivoh provides a server that redistributes Zoom or Webex content via multicast. Alternatively, customers can send video from an encoder to the Vivoh server to distribute any live video source. In this case, no dependency upon cloud-based services is required.

This creates the most reliable, secure, and simple way to reach large numbers of employees who are onsite without disrupting your enterprise network.

	Lauren Delwiche - Lauren leads the Multicast Menu project and helped Vivoh understand how multicast video content can be discovered and made available via the AMT protocol. Lauren recently spoke at the IETF 114 conference about her work and will be starting college at Yale this Fall.
	Natalie Landsberg - Natalie leads the AMT in VLC project and worked with Vivoh to help us understand the AMT protocol and to create a Python-based version with playback in the browser. Natalie recently took a full-time engineering position at CradlePoint, a networking equipment provider.
	Reuben Pillai - Reuben helped Vivoh with AWS automation and monitoring which is used for Vivoh OnTime. This included building AWS EC2 instances, setting up Target Groups, Load Balancers, and Auto Scaling Groups. Reuben is now a rising junior at Loyola University Maryland.
	Matthew Tran - Matthew wanted to dive into C programming by building a multicast relay. After Natalie ported her AMT library to Python, Matthew ported his relay to Python and helped Vivoh build out a Python-based AMT multicast player. Regarding his experience with Vivoh: "This internship was a wonderful learning experience for me ... I have learned so much about broadcasting video during the past six weeks and have gained confidence working under your guidance." Matthew is now a rising junior at George Mason University.

Vivoh is fortunate to have the opportunity to work with such great people. Vivoh is eager to support the adoption of the multicast protocol with contributions to the open source community as well as with our commercial offerings.
