I just published QTFastStart, a Cocoa wrapper around the qt-faststart.c program by Mike Melanson. qt-faststart reorders the components of an H.264 MPEG4 video file to enable progressive download playback of certain H.264 videos in the Flash Player browser plugin. Read Tinic Uro’s description of the issue.

This GUI wrapper was whipped up in a matter of minutes and is thus rather unpolished.

I have no H.264 files with their moov part at the end to test it so I don’t know if this works as intended. Let me know if you try it out.

Here is an example of the new H.264 video codec support. If you’re running the newest beta of the Flash player plugin, you should see the video here:
