You're welcome, Jonas!
Thanks to you, indeed.

I have a question, though.
At the beginning of the new debian/copyright file, I read the following

| Comment:
|  Because the libavcodec-extra-* package (since libavcodec-extra-54)
|  links against libraries licensed under Apache-2.0 (not compatible with
|  LGPL), effective license of that package and libav-dbg is GPL-3+.

This does not look too clear to me.

Which license is the libavcodec-extra-* package released under?
LGPL-2.1+ or GPL-2+ ?

By looking at the rest of the debian/copyright file, it seems to me
that the answer is LGPL-2.1+ : can you confirm, please?

If this is really the case, then, although it's true that Apache-2.0 is
not compatible with GPL-2, I don't think it's accurate to say that
Apache-2.0 is not compatible with LGPL...

Moreover, why should the effective license of the libavcodec-extra-*
package be considered GPL-3+ ?
This seems to imply that I cannot distribute a program under a
GPL-3-incompatible license (for instance, BSD-4-clause) linked with
libavcodec-extra-*: I don't see any reason why such a program should be
considered as legally undistributable...

Please clarify the situation, and let's see whether we can find a
clearer formulation for the above-quoted comment.

Thanks for your time!

 New GnuPG key, see the transition document!
