[MPlayer-users] Android port of MPlayer

[Alessandro Pezzoni]

Hi,
MPlayer is released under the GNU GPL2 license [1], which requires him
to publish the modified source code if his program is publicly
available.

"- Does the GPL require that source code of modified versions be
posted to the public?
    The GPL does not require you to release your modified version. You
are free to make modifications and use them privately, without ever
releasing them. This applies to organizations (including companies),
too; an organization can make a modified version and use it internally
without ever releasing it outside the organization.

    But if you release the modified version to the public in some way,
the GPL requires you to make the modified source code available to the
program's users, under the GPL.

    Thus, the GPL gives permission to release the modified program in
certain ways, and not in other ways; but the decision of whether to
release it is up to you."

Taken from the GPL FAQ [2].

So I think he is legally bound to publish his source code.

Regards,
Alessandro
