Subject: [gentoo-dev] [PATCH] gstreamer-meson.eclass: New eclass required for gstreamer-1.18.0+
Date: Wed, 17 Mar 2021 01:49:57
Message-Id: 20210317014953.9319-1-contact@hacktivis.me
1 Gstreamer switched to meson in 1.16.0 and removed autotools support in 1.18.0,
2 this eclass is an update of gstreamer.eclass.
3
4 One significant change between autotools and meson is that in the latter we
5 don't have easily extractable semantics in the buildsystem to get a list
6 of plugins with extraneous dependencies that we currently split in other
7 packages.
8 Hence the rather ugly but currently required GST_PLUGINS_DISABLED block.

49 +# also list any packages that provide explicitly requested plugins.
