`VideoMultiviewFramePacking` represents the subset of `VideoMultiviewMode`

It can be used by elements that provide a property to override the

The rank of the feature
<!-- trait PluginFeatureExt::fn load -->
Loads the plugin containing `self` if it's not already loaded. `self` is
unaffected; use the return value instead.
Normally this function is used like this:
```C
GstPluginFeature *loaded_feature;
loaded_feature = gst_plugin_feature_load (feature);
// presumably, we're no longer interested in the potentially-unloaded feature
gst_object_unref (feature);
feature = loaded_feature;
```
# Returns
a reference to the loaded
feature, or `None` on error
<!-- trait PluginFeatureExt::fn set_rank -->
Specifies a rank for a plugin feature, so that autoplugging uses
the most appropriate feature.
## `rank`
rank value - higher number means more priority rank

<!-- struct Registry -->
One registry holds the metadata of a set of plugins.
<emphasis role="bold">Design:`</emphasis>`
The `Registry` object is a list of plugins and some functions for dealing
with them. Each `Plugin` is matched 1-1 with a file on disk, and may or may
not be loaded at a given time.
The primary source, at all times, of plugin information is each plugin file
itself. Thus, if an application wants information about a particular plugin,
or wants to search for a feature that satisfies given criteria, the primary
means of doing so is to load every plugin and look at the resulting
information that is gathered in the default registry. Clearly, this is a time
consuming process, so we cache information in the registry file. The format
and location of the cache file is internal to gstreamer.
On startup, plugins are searched for in the plugin search path. The following
locations are checked in this order:
* location from --gst-plugin-path commandline option.
* the GST_PLUGIN_PATH environment variable.
* the GST_PLUGIN_SYSTEM_PATH environment variable.
* default locations (if GST_PLUGIN_SYSTEM_PATH is not set).
Those default locations are:
`$XDG_DATA_HOME/gstreamer-$GST_API_VERSION/plugins/`
and `$prefix/libs/gstreamer-$GST_API_VERSION/`.
[$XDG_DATA_HOME](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) defaults to
`$HOME/.local/share`.
The registry cache file is loaded from
`$XDG_CACHE_HOME/gstreamer-$GST_API_VERSION/registry-$ARCH.bin`
(where $XDG_CACHE_HOME defaults to `$HOME/.cache`) or the file listed in the `GST_REGISTRY`
env var. One reason to change the registry location is for testing.
For each plugin that is found in the plugin search path, there could be 3
possibilities for cached information:
* the cache may not contain information about a given file.
* the cache may have stale information.
* the cache may have current information.
In the first two cases, the plugin is loaded and the cache updated. In
addition to these cases, the cache may have entries for plugins that are not
relevant to the current process. These are marked as not available to the
current process. If the cache is updated for whatever reason, it is marked
dirty.
A dirty cache is written out at the end of initialization. Each entry is
checked to make sure the information is minimally valid. If not, the entry is
simply dropped.
## Implementation notes:
The "cache" and "registry" are different concepts and can represent
different sets of plugins. For various reasons, at init time, the cache is
stored in the default registry, and plugins not relevant to the current
process are marked with the `PluginFlags::Cached` bit. These plugins are
removed at the end of initialization.

<!-- impl Registry::fn fork_is_enabled -->
By default GStreamer will perform scanning and rebuilding of the
registry file using a helper child process.
Applications might want to disable this behaviour with the
`Registry::fork_set_enabled` function, in which case new plugins
are scanned (and loaded) into the application process.
# Returns
`true` if GStreamer will use the child helper process when
rebuilding the registry.
<!-- impl Registry::fn fork_set_enabled -->
Applications might want to disable/enable spawning of a child helper process
when rebuilding the registry. See `Registry::fork_is_enabled` for more
information.
## `enabled`
