I often use jhead to examine EXIF headers in JPG files from my digital camera and I also use jhead to fix EXIF time stamps in those files.
But what I'm looking for is an equivalent tool for AVI and MOV movie files which I also get from my cameras. Most important would be to be able to change the time stamps in these files. Using aptitude search I haven't found anything to do this. Using strings -a on those files, I see usually three identical strings of the format YYYY:MM:DD HH:MM:SS. I could write a simple tool to overwrite these strings with the desired time stamp, but I don't know enough about the file formats to be sure not to corrupt the file, e.g. because of checksums or other items in the file that need to be changed too.
