| These controls are only available if the conference |
|
| is configured with content enabled, and if the |
|
| participant is contributing a main video channel. |
|
| This control causes the MCU to |
|
| attempt to use the participant's main |
|
| video channel as the conference's |
|
| content channel source. This will not |
|
| be possible if the conference already |
|
| has an active content channel source |
|
| (either an endpoint's content video |
|
| channel or another participant's main |
|
| video activated via this control). |
|
| This control causes the MCU to stop |
|
| attempting to use the participant's |
|
| main video channel as the conference's |
|
| content channel source. It is necessary |
|
| to use this control to switch to using a |
|
| different endpoint's primary video |
|
| channel or to enable content video |
|
| contribution from endpoints. |
