Hallo, Hans-Christoph Steiner hat gesagt: // Hans-Christoph Steiner wrote:
Because of the rules of the GPL, there was never a point were PiDiP wasn't available under the GNU GPL. The BSD license with the added clause can not override the original GNU GPL. It can be offered as an alternate license to the GNU GPL as long as the complete sources are available under the terms of the GNU GPL.
Therefore all versions of PiDiP up til now are available under the GNU GPL. That could change in the future if the GPL'ed effectv code was removed.
Most files in Pidip are GPL according to comments in the source code. The "LICENSE.txt" does not apply to these anyway. Quote:
This software is copyrighted by Yves Degoyon and others. The following terms (the "Standard Improved BSD License") apply to all files associated with the software unless explicitly disclaimed in individual files:
It might also be important to note, that the "NOT FOR MILITARY OR REPRESSIVE USE !!!" restriction is written *before* above statement, which then say, that the "following terms" apply to the sources. So the former restriction might not apply at all. Rejoice, soliders and dictators!
Here are some quick greps for GPL info in the source:
(externals/pidip/modules) $ grep -L "GNU General Public License" * CVS Makefile Makefile.in pdp_aging.c~ pdp_colorgrid.c pdp_colorgrid.tk pdp_colorgrid.tk2c pdp_mp4audiosource.cpp pdp_mp4audiosync.cpp pdp_mp4config.cpp pdp_mp4playermedia.cpp pdp_mp4playersession.cpp pdp_mp4videosource.cpp pdp_mp4videosync.cpp tk2c.bash
(modules)-$ grep -l "GNU General Public License" * | wc -l 75 (modules)-$ grep -L "GNU General Public License" * | wc -l 15
Distributing a version with the 15 critical modules removed would be permitted.
BTW: PDP, on which Pidip relies, is GPL as well. While it may be possible to remove EffecTV from Pidip, it is not possible to remove the dependency on PDP.
Ciao
