how can be used a non Direct Show camera in Vision Assistant 8.5?

Dear Brad and Jaidev,

There is a file called qdv.dll in System32 which is a decoder for DV format.

It is written by microsoft for converting DV into PAL in 720 X 576 resolution.

Is there any way to decode this file in 'C' and rewrite again the pixel resolution with the help of Labview Pro 8.5.

Regards

Hi Sandesh,

Unfortunately, it is not possible to reconstruct C code from a dll. A dll is a binary image that gets loaded into system memory. Doesnt Microsoft already have functions in Directshow to do this? http://msdn.microsoft.com/en-us/library/ms783495(VS.85).aspx 

It might be possible (need clarification) to make directshow calls in LabVIEW but if you have no experience with COM programming, I would not recommed it.

Thank you,

Jaidev
