Streaming JPEG-Format Data to WMV or Animated GIF

[AustinMcElroy]

Hello everyone,

I am having a tough time coming up with an anwser for this question.  I have JPEG-format data that I have not yet saved, which is in RAM, that I would like to use to build a  Power Point friendly movie format (WMV or animated GIF).  The catch is, I would not like to save the data as a .jpg to the hard disk first, but would like to build up my movie/gif dynamically, i.e. as new JPEG-Format data is collected.  AVI has been ruled out as a format due to file size issues and the cost of purchasing NI Vision.  There are a few  sparse view ActiveX based controls to implement in Labview, but they all require saving the data to the hard-disk first.  Could anyone offer any help for a solution to this problem?  I am comfortable with integrating C/C++ DLLs into labview, and am semi-comfortable with ActiveX, so any source code, utils, ect would be much appriciated.

Thanks,
Austin

Hi Austin,

I wanted to let you know that you don't have to get NI Vision to save an AVI - it comes with the free IMAQ driver download. I personally don't know of any utilities to do what you are describing, but I searced for "how to save images to a wmx file programmatically" and got a ton of hits. Good luck!
