Can you edit the metadata on an MP4 file without writing to a different output file?

[John-Dean]

Hello,

I've been trying to get the C++ interface for this program working, and I sucessfully have it reading the metadata from an MP4 file and logging it out.

When I try to remove this metadata, using entry.RemoveFromFile() I then need to save the changes, by doing something like AP4_FileCopier::Write(*input_file, *output);

Is there a way to do this without making a new file? I've already tried feeding in the AP4_ByteStream used to generate input_file in this case, but that doesn't seem to work.

Thank you.
