Hey,

do I always have to copy the entire video file in order to add or update data in UserBoxes?

I'm working on Android and to copy an entire video that can be several GB in size just to change some XMP data seems like a bad idea.

Is there a better and still reliable way of doing this?

Cheers, Ralf
