Hello nolsqn,

I have a few questions about your software setup, and what exactly you mean by “bitstream”. Our NI-IMAQ functions palette contains several AVI functions. See http://digital.ni.com/public.nsf/allkb/0A4D5BF47FD3FF0186256E9A004FD671?OpenDocument “Writing a Compressed AVI File with IMAQ Vision” for an example. Which version of LabVIEW are you using? Do you have any NI-IMAQ or NI-VISION software installed?

Hello nolsqn,

I have attached a simple example that demonstrates how to convert an AVI file into digital information. Note that this VI requires that you have the NI-VISION software installed on your machine. Also, this VI was created using LV 8.5 and will not work with previous versions. I hope this helps.

Hello nolsqn,

The example in my previous post has 2 outputs, U32 and U64, to demonstrate that both 2-D array data types can be generated from the original U32 images (see the Image Create input on the IMAQ Create VI). You could use either one in your program, depending on what you want to do with the image data.

I have attached an example that shows how to use ActiveX controls to open an AVI file in LabVIEW. It uses Windows Media Player. I tested it out to make sure that both audio and video play. Post back and let me know how this works out. Glad to help 🙂
