The only thing I know for sure, is that it's been used with Final Cut 
Pro since many years, and that this feature is present in Quicktime 
(.mov) since a long time.

Also I added this feature to FFmpeg since quite some time now, and some 
users already used it.

The fact that you didn't know about it, absolutely does not imply that 
all the users around the world don't know about it.

Now the good thing about using computers is that you learn new things 
every day even after 10 years and when you are 34. Here is a new thing 
you just learned, but I think this discussion is going off-topic for 
ffmpeg-devel mailing list, user questions belong to ffmpeg-user mailing.

Well, like I said, patch welcome.
