•
General: WebEx is a browser based web conferencing client-­‐server application (Hosted) utilizing a Java Plug-­‐in. Highest video resolution is 360p for Free Account and 720p is offered on the Premium Account. A video compatibility issue exists in WebEx version 28.6 and below. This is attributed to a limitation in the WebEx client to support MJPEG decoding. The Vaddio product are MJPEG imaging device. MJPEG support was added to WebEx in the WBS 28.7 release. o In process for Cisco Partner Certification of HD-­‐USB Camera Table 2.2-­‐ Tested Versions WebEx Version Operating Systems EasyUSB Tools Product WBS 28.7 and Windows 7 EasyUSB Mixer Amp above MAC OS X ClearView HD USB AV Bridge Recommended Configuration: o Audio-­‐ Select the EasyUSB Mixer/Amp as the Speaker and Microphone within WebEx.

This will list call stats and identify if audio/video problem is associated with available bandwidth. Re-­‐
establishing call can sometimes help. Skype has aggressive AGC that can cause mic audio to clip. Recommendation is to disable “Automatically adjust mic settings” and set Skype gain manually. Skype requires the WebCam to be Skype Certified in order to support 720p calls. The HD-­‐
USB Camera is currently not certified. There are open-­‐source applications that can be downloaded that will force Skype into HD video mode.

Troubleshooting: Symptom Potential Issue Can’t Select Adobe UVC HD-­‐USB Enumeration Camera as source No Audio Must Allow Connect to access audio device Must Connect Audio No Video Must Start Video Video Artifacts at low resolution Downscaling artifact with Connect client Resolution The HD USB-­‐Camera is defined as a generic UVC device. It was found that Adobe does not recognize the distinction between generic UVC devices if multiple are connected to the PC. It will always pick the first UVC device plug-­‐in. Fix is to disable any Non Vaddio UVC device in operating system (Win XP or Win 7). Upon entering a meeting room, a pop-­‐up is presented to user asking if Connect can access PC audio devices. Must confirm access for audio to work. User is required to connect mic in the application for audio to start. User must share video in the application for WebCam to activate. The HD-­‐USB camera possesses an edge enhancement feature producing crisp video edges between object in the shot. It has been found this cause scaling artifacts on some softclient on low resolutions.

PC Requirements: All UC softclients have minimum PC requirements for the application to run properly. Typically, higher PC CPU requirements are need to achieve HD video. Customers that are unable to obtain HD calls should verify PC meets softclient minimum CPU requirements. Network Bandwidth: Most UC clients require a minimum of 1-­‐2 Mb bandwidth to support a 720p call. The UC clients will typically automatically reduce video resolution based upon available bandwidth. In addition, poor bandwidth can result in both video and audio anomalies during a call. USB Connections: The EasyUSB video devices require a USB 2.0 High Speed connection to the Host PC for HD Video. USB Host Controller, Hubs, or Repeaters that are not USB 2.0 High Speed may result in video and audio anomalies occurring. Audio & Video Device Selection: PC User must select the EasyUSB Tools devices as the WebCam and Audio device within the operating system and UC client for the products to work properly in conferencing application. Mixer/Amp must be selected as both Record and Playback device for AEC to work properly. Windows 7: o No major issues found. Windows XP: o User must have SP3 for USB volume controls to work properly with EasyUSB Mac OS X: o Mac OS 10.6 does not support volume control reporting to USB devices. If EasyUSB Mixer/Amp is connected to Mac running 10.6 or below, the volume indicators on the EasyMic Mic Pod will not be synchronized with the MAC. This works with 10.7 or above.
