Testing your Workstation
To ensure that your workstation can display the video preview window:
1
Polycom, Inc.
Video Preview of the video sent from the conference to the participant is shown
according to the line rate and video parameters of the level threshold to which the
participant is connected.
In versions up to and including Version 7.2.2, only users with Administrator
authorization could request to view a video preview. In later versions, all users can
view a video preview.
Video preview is supported with MPM+ and MPMx cards.
Only one preview window can be displayed for each RMX Web Client connection
(workstation).
Only one preview window can be displayed for a single conference and up to four
preview windows can be displayed for each media card on different workstations (one
per workstation and one per conference). For example, if the RMX contains two media
cards, and there are 5 conferences running on the RMX, if five conferences are running
on the same media card, only four conferences can be previewed from four different
workstations. If four or less conferences are running on one media card and the
remaining conferences are running on the other media card, all five conferences can be
previewed.
Live video that is shown in the preview window does not include the Content when it
is sent by the participant.
Video Preview is supported in cascaded conferences.
If the video preview window is opened when the IVR slide is displayed to the
participant, it will also be displayed in the video preview window.
Video Preview is supported with H.264 High Profile.
Video Preview is not supported for endpoints using the RTV protocol.
Video Preview is disabled in encrypted conferences.
Video preview cannot be displayed when the participant's video is suspended.
Participant's video preview and the CMAD window cannot be open and running
simultaneously on the same PC as both require the same DirectDraw resource.
