Jabber Hardware

[david.sharp]

Hi

I have a question about Jabber for video hardware support.

I have seen that in a forum post as a question and answer the forum post states that the requirements for Jabber to operate on a computer are as follows

Video

OpenGL version 1.2 or later

Hardware support for DX8

Cameras

Cisco telepresence camera

Built in laptop camera or USB external camera

In my experience the results from the software greatly very dependant on the platform, so what I wish to ask is as follows.

what should we do in the event that a system follows all of the above recommendations and the drivers have been updated to the latest version but yet Jabber fails to install or fails to recognize the camera.

I expect a dxdiag capture would be required, and maybe a debug file from the Jabber client, but if Jabber is failing to install where would this information be stored.

in addition to this, does Cisco have any specific manufacturer recommended lists for graphics adaptors and camera's, I have seen on the Cisco web site there is a list of supported camera's that has been tested.

Cheers

Dave

I think Jabber Video very seldom fails to install. If it does, open up a TAC case. In the case installation fails I would write down any error messages displayed.

OpenGL issue

What we have seen lately is that some versions of display drives are not updated with respect to a updated component (Clutter) in OpenGL. The feature set is still OpenGL 1.2, but this means that a display adaptert that is supporting OpenGL 1.2 not necessarily has the updated component and thus Jabber Video will fail during startup (it does a small graphic test before it starts)

I just ran a test on a Lenovo X200 (Lenovo´s with Intel Mobile 4 express grahics chipset)are the ones we have seen this failure on) with the following results:

• 8.15.10.2021 released 14.12.2009 NOT OK
• 8.15.10.2182 released 19.07.2010 OK
• 8.15.10.2413 released 03.06.2011 OK
• 8.15.10.2555 released 19.10.2011 OK

To resolve this

Windows Update

• Many users report that they can use the Windows Update to get the latest driver. They need to enable "optional updated" in order to achieve this.

Manually Installing the Intel driver

• Point your browser to http://www.intel.com/p/en_US/support/highlights/graphics/4m
• Choose view all from latest downloads
• Select your operating system in the left pane, and drivers in the right pane.
• Download driver and update the driver. This will usually require a reboot.

We are eager to know if the graphics problem is seen on other platforms (in that case - which brand - operating system and driver versions). The component that has been upgraded is a common component used by many programs so this is not a Jabber Video issue, rather a driver issue (failure to update the component in the driver by the vendor)

Crashes

For re-occuring crashes, a TAC case should be opened and the following questions should be answered:

1. Is it reproducible? This can range from "Not at all" through "I don't know" to "Yes, every time"
2. What steps are necessary to reproduced the crash?
3. What sort of PC are we talking about? For Macs, this will be included in the crash dump but for Windows, a DxDiag is great.
4. The error dialog generated by the OS. Sometimes when Jabber Video/ Movi crashes, a notification window will appear telling you so; it will also give a filename, line number and error message. If possible, get a screenshot of this.
5. A crash dump file. This contains info about the code that was running at the time of the crash, and will hopefully give development enough information to fix it. Windows Error Reporting, Dr Watson or OSX crash dump are nice to attach.

Cameras

You are right, there is a tested camera list on Cisco.com:

http://www.cisco.com/en/US/docs/telepresence/endpoint/articles/cisco_telepresence_movi_tested_cameras_kb_377.shtml

I also know that the Logitech C920 will be working in Jabber Video 4.5.

If you have a camera that should work but doesn´t: Make sure the camera is working with other applications or with another PC to rule out that it´s a camera or camera SW issue. Try to upgrade the camera software (if possible). If it´s on the tested list - open up a TAC case. (Or better - purchase a Precision HD USB )

We do not have any recommendations wrt laptop manufacturer or graphics drivers. The most important thing is the capability of the CPU and not the graphics card/GPU since the H264 encode/decode is done by the CPU. Running the quick setup will in many cases provide an indication of what kind of performance the PC is up to and how good video it can produce.

Hope this helps.

If I find out more wrt failing installs I will update this post.
