So do you agree that asking for diff is not sufficient for to meet any GPL /
LGPL requirement? If you ask for it, it should be advertised as to satisfy
"ffmpeg team" in general instead of FFMpeg licensing terms (which are

Just to state the problem (so everyone is aware of it): If someone takes the
GOM's modified ffmpeg library, incorporate it in their project and modify
it, there will be no indications that the files ever came from GOM and it
will break the lineage that LGPL 2.a tries to achieve. The guy will modify
two files (for example) and put notices of modifications on the top of those
two files, but then he will appear to be in breach of LGPL 2.a because there
are another dozen files modified by GOM not carrying any notice of
modifications and you guys will have to go a second time in the
(blacklist/legal) process with this new guy.

Anyway feel free to ask anything you want, I just wanted to point out that
it is easy to think that you ask for diff as being something towards
complying with LGPL. If it's just me that sees that then I'll shut up.
