SDI Capture Card programming question

Hi All,

I am new to cuda programming and I no idea whats going on with programming with CUDA and NVIDIA SDI capture card. I am using WinXP 32bit + NVIDIA Quadro 4000 + MS Visual Studio 2010

I am following the sample cudaDVP (cuda runtime) code provided with the capture card. I have finally been able to process with cuda. I have a separate .cu file that include the kernel functions and kernel calls. It compiles but when I run the file I am getting assert errors now. How do i fix that? If not how can I process video with cuda after sdi capture card binds the video to memory?

My second problem is with audio. In the manual it doesn’t detail how to extract the audio information and how to play the sound in pc.

please help!

Thanks
Ruofan
