Disable Hardware Acceleration

I just tried the binary distribution of the RI and, as the instructions stated, I had to disable hardware acceleration on my machine. Failure to do so caused the entire machine to lock up and become completely unresponsive (I tested it twice). It worked fine after I turned off hardware acceleration.

Is this issue being investigated so that (certain hardware configurations) do not have to have hardware acceleration disabled in order to run the RI?

Here are two Windows XP configurations that work (for me) with hardware acceleration enabled:

NVIDIA GeForce 8800 GTX (driver: NV4_DISP.DLL 6.14.11.6921 - NVIDIA Compatible Windows 2000 Display driver, Version 169.21)

NVIDIA Quadro NVS 110m (driver NV4_DISP.DLL 6.14.11.5683 - NVIDIA Compatible Windows 2000 Display driver, Version 156.83)

The first is a Dell XPS 410 workstation and the second is a Dell Latitude D820 laptop. These are running the wxWidgets flavor of the emulator.

We have not yet identified the hardware configurations which exemplify this behavior. Could you please provide a list of your system's configuration to help us track this problem down?

Greetings -

I have the same issue/problem with the OCAP RI. I must disable video acceleration for the default RI on Windows or else my Windows XP machine will "blue screen" or will lock up solid, requiring a hard reboot. I have a Dell Latitude D830 running Windows XP (latest updates) with a Mobile Intel 965 Express Chipset installed. I am using OCAP V1.1.1RelA.
So, when I am running ClientSim, I need to turn *on* video acceleration. When I am running the RI Platform simulator, I need to turn *off* video acceleration.

Just FYI -

There are fundamental differences between the enableTv Client Simulator and the CableLabs RI Emulator. The Client Simulator uses DirectX while the RI Emulator uses OpenGL.

I think these issues are related to the HW graphics chip technology and the installed OpenGL drivers on the Windows XP system. If we can gather the information on the systems underlying chip technology and the drivers being used, we may be able to come up with a solution.

Mark,

Almost everyone in TvWorks experience the same type of the problem. We also use OCAP-RI video control embedded in Eclipse (WIN32 target twisted). There are two different scenarios also depending where the stack is running:
- embedded in same process (OCAP stack running in the same process as Eclipse),
- embedded in separate process (OCAP stack and Eclipse are running in separate processes).
Generally we have same process scenario working with acceleration. But separate process scenario is troublesome. Here are the configurations we have:

Alex: [Dell D830, NVIDIA Quadro NVS 135m (driver ver. 6.14.11.8585)] work both scenarios with either accelleration on or off
Sean: [Dell D820, NVIDIA Quadro NVS 110m (driver ver. 6.14.11.5683)] separate process scenario works only with acceleration off
Mike: [Dell D830, Mobile Intel 965 Express Chipset (driver ver. 6.14.10.4926)], separate process scenario works only with acceleration off
Scott: [Dell D820, NVIDIA Quadro NVS 110m (driver ver. 6.14.10.8313)] separate process scenario works only with acceleration off

I hope this will help you to pinpoint the problem with OpenGl.

-Alex.
