Capturing Video
You can control the video capture behavior of the Cisco Unified Videoconferencing Connector Conference Client by using the Force High Capture Frame Rate option.
When unchecked, the Cisco Unified Videoconferencing Connector Conference Client does not capture video at 30 fps under certain circumstances (for example, when insufficient CPU resources are available).
When checked, the Cisco Unified Videoconferencing Connector Conference Client overrides the 30 fps video capture limit.
Note Because the Cisco Unified Videoconferencing Connector Conference Client does not include Centrino processors when calculating CPU resources, clicking this option ensures video capture is enabled when Centrino processors are present in laptops and so on.
Procedure

Step 2 Access the Cisco Unified Videoconferencing Connector Conference Client.
Step 3 Click the Settings tab.
Step 4 Click the Advanced tab.
Step 5 Click the Connect Only To Trusted Server check box under Network.
Note Because the Desktop server ships with a self-signed certificate which is not trusted, checking this option with a default installation causes the Cisco Unified Videoconferencing Connector Conference Client to fail to connect to the server. Administrators can replace the default self-sign certificate as required.
Sending RTP Media Packets via TCP
You can instruct the Cisco Unified Videoconferencing Connector Conference Client to send RTP media packets via TCP, rather than via UDP.
