GPS info to MP4

Hello,

I've tried to add GPS information to an MP4 file, and I'm getting "Error: Writing of MP4 files is not yet supported". That is a good error message and explains it well enough, but I'm wondering if MP4 files can't yet handle GPS information, or is it the case of ExifTool not yet having the ability?

I'm hoping to address videos in a flex application via their spatial information. Any help is much appreciated.

Thanks in advance.
Jeff

I haven't yet seen GPS information in MP4 videos, but in AVCHD videos
I have seen GPS embedded in the H264 video stream which is a codec
also supported for MP4.  As far as I know there is no public standard for
this, but exiftool does extract GPS from the AVCHD H264 stream.
