- installPluginsAsync

  Requests plugin installation without blocking. Once the plugins have been installed or installation has failed, func will be called with the result of the installation and your provided userData pointer.
  This function requires a running GLib/Gtk main loop. If you are not running a GLib/Gtk main loop, make sure to regularly call g_main_context_iteration(NULL,FALSE).
  The installer strings that make up detail are typically obtained by calling gst_missing_plugin_message_get_installer_detail() on missing-plugin messages that have been caught on a pipeline's bus or created by the application via the provided API, such as gst_missing_element_message_new().
  It is possible to request the installation of multiple missing plugins in one go (as might be required if there is a demuxer for a certain format installed but no suitable video decoder and no suitable audio decoder).
  
  Parameters:
  
  details - NULL-terminated array of installer string details (see below)
  
  ctx - a GstInstallPluginsContext, or NULL
  
  func - the function to call when the installer program returns

- installPluginsSupported

  TRUE if plugin installation is likely to be supported.
- installPluginsSync
  
  public static InstallPluginsReturn installPluginsSync(@Nullable String @Nullable [] details, @Nullable InstallPluginsContext ctx)
  
  Requests plugin installation and block until the plugins have been installed or installation has failed.
  This function should almost never be used, it only exists for cases where a non-GLib main loop is running and the user wants to run it in a separate thread and marshal the result back asynchronously into the main thread using the other non-GLib main loop. You should almost always use gst_install_plugins_async() instead of this function.
  
  Parameters:
  
  details - NULL-terminated array of installer string details
  
  ctx - a GstInstallPluginsContext, or NULL
  
  Returns:
  
  the result of the installation.
