mmread and aviread don't work

Hi guys

I'm trying to read an avi file using mmread and aviread, but failed.

It said that "Unable to locate decompressor to decompress video stream."

After calling aviinfo, I get: VideoCompression: 'FMP4'

What kind of decompressor should I install to solve this problem

Please see http://www.downloadatoz.com/download/50273,fmp4-codec.html

I don't know if I would trust downloading anything from that particular site (it is not one I am familiar with), but it does list several decoders.

Note: if you happen to be using 64 bit Windows then you might have difficulty getting a decompressor.

check this one

and install the required codec for your system....

Good advice in general, but FMP4 is not on that list.
