This is another bug.

Sorry: Is there this (other) bug or not?
I don't understand...

If you do "huge tests" and you find problems and 
you do not report them, it is unlikely that they 
get fixed. Do you agree?


I had not realized you can use ffv1 in avi with 
third party applications. You have explained that 
it works fine and I did - iirc - answer that I 
understand now (but not before).

As said, please elaborate.
Iiuc, you write above that this is not reproducible.

Please point me to the report.

You have to read the GPL and the LGPL again.
(Yes, this is extremely important, your question 
implies to me that you did not understand its 
implications for you as a user.)
