installPluginsSync

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 [gstpbutils.global.installPluginsAsync] instead of this function.
