AFAIK, you are not a lawyer, are you ?

Well, I'm sorry to have to say this, but you also got to respect other
developpers' choice. It a consensus cannot be reached, I'm afraid we
will have to vote.
I already stated my opinion here. I won't refuse any code under LGPL 2.1

Yes, LGPL is preferred. However there is no reason to be a license
zealot. Coding is fun, and our goal was always to support as many
formats as it exists in the world. Your fight is bringing us away from
our main goal.

Yes, I thank you for this. However if people does not want to relicense,
you got to respect this, and our choice to use their code conforming to
their choice of license, if we choose to do that.

Why don't you step up to implement then if you claim it would take less
time ? Kenan is quite generous to step up implementing/adapting the
code, I don't see why we should refrain him.
