How correctly distribute GStreamer package with Cerbero?

[Marc Leeman]

Just repackage GStreamer from a newer version of Ubuntu, we're doing
this all the time for Debian.

e.g. (using debian), if you want to re-compile the packages from sid
(1.16) to buster, add the following line in some sources file

deb-src http://www.debian.org/debian sid main contrib non-free

$ sudo apt-get update
$ apt-get source gstreamer1.0
$ cd gstreamer1.0-1.16.0
$ dch -l ~mybackport+ -m "backport to buster"
$ dch -r -D buster
$ sudo apt-get build-dep gstreamer1.0
$ fakeroot dpkg-buildpackage -sa

If you want to add patches of your own, just drop them in
debian/patches/ and adjust the debian/patches/series file
