A default script `gstreamer-full-default.map` declares only glib/gstreamer symbols as public. +One can use the `gst-full-plugins` option to pass a list of plugins to be registered +in the gstreamer-full library. The default value is '*' which means that all the plugins selected +during the build process will be registered statically. An empty value will prevent any plugins to +be registered. + +One can select a specific set of features with `gst-full-elements`, `gst-full-typefind-functions`, `gst-full-device-providers` or `gst-full-dynamic-types` to select specific feature from a plugin. +When a feature has been listed in one of those options, the other features from its plugin will no longer be automatically included, even if the plugin is listed in `gst-full-plugins`. + +The user must insure that all selected plugins and features (element, typefind, etc.) have been +enabled during the build configuration. + +To register features, the syntax is the following: +plugins are separated by ';' and features from a plugin starts after ':' and are ',' separated. + +As an example: + * `-Dgst-full-plugins=coreelements;playback;typefindfunctions;alsa;pbtypes`: enable only `coreelements`, `playback`, `typefindfunctions`, `alsa`, `pbtypes` plugins. + * `-Dgst-full-elements=coreelements:filesrc,fakesink,identity;alsa:alsasrc`: enable only `filesrc`, `identity` and `fakesink` elements from `coreelements` and `alsasrc` element from `alsa` plugin. + * `-Dgst-full-typefind-functions=typefindfunctions:wav,flv`: enable only typefind func `wav` and `flv` from `typefindfunctions` + * `-Dgst-full-device-providers=alsa:alsadeviceprovider`: enable `alsadeviceprovider` from `alsa`. + * `-Dgst-full-dynamic-types=pbtypes:video_multiview_flagset`: enable `video_multiview_flagset` from `pbtypes + +All features from the `playback` plugin will be enabled and the other plugins will be restricted to the specific features requested. + +All the selected features will be registered into a dedicated `NULL` plugin name. + +This will cause the features/plugins that are not registered to not be included in the final gstreamer-full library. + This is an experimental feature, backward uncompatible changes could still be made in the future. |
