Hello, I have unpleasant news for this bug, unfortunately.

I suggested [1] to clearly document this situation, since it's currently not apparent at all.

Hi Anton, it seems to me that http://packages.debian.org/changelogs/pool/main/liba/libav/libav_0.8.4-1/libavcodec53.copyright is no longer consistent with the actual licensing status of the libav library. I assumed that it was accurate (maybe it was at the time I originally reported the bug against netgen...) and based my analysis on it! I think this should be reported to the libav Debian package maintainers. Back to the netgen issue, a quick audit of the libavcodec/, libavformat/, and libswscale/ directories in the libav source tree shows that everything seems to be licensed under the GNU LGPL or under more permissive terms, except for: libav-0.8.4/libavcodec/x86/idct_mmx.c which is licensed under the GNU GPL v2 or later.

Even though the short-term solutions are not completely satisfying (the real solution is persuading Open CASCADE S.A.S. to re-license in a GPL-compatible manner, as I keep repeating like a broken record!), I appreciate that you are trying hard to keep the affected packages in Debian.

tags 618968 +patch thanks Please, consider the following patch, which prevents of using ffmpeg in netgen build. It will, of course, cut the functionality of netgen, but will let to stay it in wheezy. The upload should be done directly to wheezy, because sid contains the version, which will unlikely go to a testing. Thanks, Anton nmu.debdiff Description: Binary data
