how to open avi with 'motion jpeg' codec

I am trying to open avi files stored on sd memory card from a casio exilim camera. Prism shows it as being a 'motion jpeg' codec. 'Open AVI' VI thows up an invalid avi session code when I try to open with labview. I'm using Labview 2011.

Do you have motion jpeg codec installed?

No, I haven't been able to find any mention of it on the NI website. I just upbraded to LV2011 hoping the 'Open avi" vi could handle these new codecs but alas it can't. Most commercial players have no trouble loading/playing these avi's. I was hoping someone might know of a patch or something to allow the 'open avi' vi to read these files.

LabVIEW AVI VIs rely on the installed codec to encode/decode.

You need download a codec for the motion jpeg.

It's very easy to find a free codec for it online.  Search bing or google instead of NI.

Hi , I downloaded and installed the motion jpeg avi codec as suggested. Restarted the computer. Open Avi still gives me an 'invalid session' error.

Hi al capern,


It looks like you have an ongoing thread here for the same issue. I spoke with Ben regarding this issue. Please continue working with him in the other thread as this issue is better suited to the Machine Vision boards. Thanks for your cooperation!
