Usually you can find that # out by grepping the source tree for 'factory_make'. If it uses playbin # plugin, consider adding media-plugins/gst-plugins-meta dependency, but # also list any packages that provide explicitly requested plugins. inherit eutils multilib multilib-minimal toolchain-funcs versionator xdg-utils case "${EAPI:-0}" in 5|6) ;; 0|1|2|3|4) die "EAPI=\"${EAPI:-0}\" is not supported anymore" ;; *) die "EAPI=\"${EAPI}\" is not supported yet" ;; esac # @ECLASS-VARIABLE: GST_PLUGINS_BUILD # @DESCRIPTION: # Defines the plugins to be built. # May be set by an ebuild and contain more than one indentifier, space # seperated (only src_configure can handle mutiple plugins at this time). : ${GST_PLUGINS_BUILD:=${PN/gst-plugins-/}} # @ECLASS-VARIABLE: GST_PLUGINS_BUILD_DIR # @DESCRIPTION: # Actual build directory of the plugin. # Most often the same as the configure switch name. : ${GST_PLUGINS_BUILD_DIR:=${PN/gst-plugins-/}} # @ECLASS-VARIABLE: GST_TARBALL_SUFFIX # @DESCRIPTION: # Most projects hosted on gstreamer.freedesktop.org mirrors provide # tarballs as tar.bz2 or tar.xz.
