Hi,
I was wondering if it’s possible to pass some configure options to FFmpeg in my PKGBUILD, in order to make it compatible with the OBS licensing requirements. I read that most of FFmpeg’s source code is GPL licensed, so surely, it should be possible to create a version of FFmpeg I will be allowed to keep in the OBS.
Thanks for your time,
Brenton
Not only possible, it’s being done already: openSUSE Software
AFAIK all these packages are “crippled” to circumvent license issues.
I copied them (i.e., the configure flags) over to my ffmpeg package in the OBS (https://build.opensuse.org/package/show/home:fusion809:arch_extra:extra/ffmpeg). I Googled this question before I asked it and apparently it’s the --enable-nonfree configure option that makes it not GPL/LGPL-compatible in its license. I didn’t have that configure option in my original package, yet @Malcolmlewis told me to delete it because it was blacklisted… Not sure if that’s because he didn’t actually look at my configure options and just assumed I had passed that option, or whether I missed something… This was my PKGBUILD https://github.com/fusion809/PKGBUILDs/blob/d12a82fafeca125787c7d16b639a8c4248add31f/ffmpeg/PKGBUILD, if you, or Malcolm himself would like to clear this up for me.
This problem is particularly relevant as building with the build flags mentioned in that ffmpeg.spec file is failing. Apparently I need a dependency called libcelt in order to build FFmpeg with these configure flags. I cannot find libcelt in the AUR or Arch repos. So I’m kinda stuck. If it helps here (https://www.ffmpeg.org/legal.html) is where I found that the --enable-nonfree configure flag breaks FFmpeg’s compliance to the GPL/LGPL licenses.

Hi
Have no idea, I see the --enable-gpl option, so assume that’s it, but
is that going to upset the rest of your builds that call ffmpeg libs?
I’m no lawyer but the openSUSE version from multimedia:libs
has been through the legal wringer for sure
