Re: iPhone Finally Caught Us...

We've been doing a lot more ipod/iphone compression for web sites and we've run into a problem where H264 files using either the m4v or mp4 extensions won't play on the iphone, but if you simply change the extension to .mov on the file, iphone plays it fine.

We have the correct mime types setup on our webserver so that's not the problem. The encoding is correct since the the exact same file plays fine by just changing the extension. We've tried using different encoding apps, including Quicktime, Handbrake, Carbon Coder and Procoder, and made sure all the specs, from codecs to pixel size and data rates are within the iphone specs, and we cannot get the m4v or mp4 files to play.

Ultimately, it's not a huge deal since they work fine by simply changing the extension. But I've found numerous posts on various Mac forums with others having the same problems and there doesn't seem to be a definitive cause or solution.

What's the magic potion for this issue?
