## Description

## Functions

### gst_player_new ()

    GstPlayer *
    gst_player_new (GstPlayerVideoRenderer *video_renderer,
                    GstPlayerSignalDispatcher *signal_dispatcher);

Creates a new GstPlayer instance that uses `signal_dispatcher` to dispatch signals to some event loop system, or emits signals directly if NULL is passed. See `gst_player_g_main_context_signal_dispatcher_new()`.

Video is going to be rendered by `video_renderer` , or if `NULL` is provided no special video set up will be done and some default handling will be performed.

#### Parameters

video_renderer | GstPlayerVideoRenderer to use. | [transfer full][allow-none]
signal_dispatcher | GstPlayerSignalDispatcher to use. | [transfer full][allow-none]

#### Returns

a new GstPlayer instance.
