Writing a Compressed AVI File in NI LabWindows/CVI with the IMAQ Vision Acquisition

[Visionist]

I'm still facing some problems when I try to save pictures from a GigE Vision camera into a compressed avi-file in a LabWindows/CVI application on Windows7.

The task is to grab images from the camera with 30 fps to monitor a process, evaluate the grabbed pictures to find certain characteristics of the monitored process and save them in an avi-file to have the possibility to load and evaluate them once again Offline if necessary.

My questions: which compression filters can I get with the NI-Imaq Vision Acquisition and Vision Development Runtime 2012 SP1? Is a mpeg4 codec available to compress quickly and effective? Can I use a third party codec or only the ones delivered with NI-Vision?

I posted the problem two times already, but there is little response up to now. Thanks

The encoding algorithm, or codec, that's used for compression needs to present on your system. When I had done some research on this sometime back, I found that if your custom codec could align with the DirectShow architecture, then your codec would work with IMAQ AVI functions.The codecs that are available may vary from system to system, depending on what software is currently installed.
