Solution:
Sharing video in a Cisco Webex Video Platform (V1, V2) (formerly CMR)/CMR Hybrid Meeting is not supported using the normal Content Sharing options.

Unlike Webex-only meetings, Cisco Webex Video Platform (V1, V2) (formerly CMR) & Hybrid (formerly Webex-enabled TelePresence) meetings with video & presentation share* are standards-based.

*for both Webex to TelePresence and Webex to Webex sharing

Presentation share specifications for Cisco Webex Video Platform (V1, V2) (formerly CMR) from a TelePresence (TP) endpoint are only at 720p/5 frames per second (FPS).
The 5 frames per second would prevent TP endpoints from sharing at the desired quality or may even result in a black screen to the viewers. Users can downgrade their presentation quality on the endpoint device, but the quality would most likely be between 360p and 480p, which would result in a grainy/pixilated video un-viewable to the remote audience.
Video requires at least 15 fps for standard quality. Doc sharing is the only supported method to support 720p quality, which is not currently a supported sharing method by Telepresence endpoints.

CMR Hybrid option ONLY:

With Conductor XC 3.0/TS 4.1: Adds 1080p resolution share in CMR Hyrbid only (Conductor & TS required)
(Note: 3Mbps bandwidth required at all Webex clients to see 1080p share in a CMR Hybrid meeting)
 

Workaround for Cisco Webex Video Platform (V1, V2) (formerly CMR)/CMR Hybrid solutions:

• Share video using the video stream vs. the content stream.
• This option is only supported using Cisco Telepresence endpoints. Third-party endpoints will need to refer to their documentation or manufacturer for assistance.

Steps from the endpoint:

1. Log in to the endpoint via the WebUI.
2. Click on the Call Control option at the top.
3. Call into the Cisco Webex Video Platform (V1, V2) (formerly CMR)/CMR Hybrid meeting, which must be started if you have not called in just yet (otherwise, use touch to dial in)
   • Username@sitename.Webex.com or meeting#@sitename.Webex.com or meet@sitename.Webex.com
      
4. Once connected, use the Main Source drop-down to select Camera or PC:
   
   
    

To get audio, your PC speakers will need to be near the mic. Audio is not shared within the video stream.

Steps from the Webex clients:

1. When the content is in the Active Speaker window, click on the attendee’s name in the bottom left corner.
   
   The Lock Focus on a Participant pop-up will appear.
    
2. Select the option The active TelePresence speaker, then click OK:
   
   

If Webex attendees want to view this in full screen:

1. Right-click on the video.
2. Select the option to move to full screen.
3. Then to exit full screen, select the option in the upper-right.

Note: CMR Hybrid becomes EoS effectively on February 28, 2021. After 02/28/2021, CMR Hybrid service will continue till April 2021 (EOL) and at that point, CMR Hybrid customers will be auto migrated to the latest version of CMR Cloud.
