Render 1000 audio buffers (of default size) as fast as possible.

## Details

### GstFakeSink

    typedef struct _GstFakeSink GstFakeSink;

The opaque GstFakeSink data structure.

### enum GstFakeSinkStateError

    typedef enum {
      FAKE_SINK_STATE_ERROR_NONE = 0,
      FAKE_SINK_STATE_ERROR_NULL_READY,
      FAKE_SINK_STATE_ERROR_READY_PAUSED,
      FAKE_SINK_STATE_ERROR_PAUSED_PLAYING,
      FAKE_SINK_STATE_ERROR_PLAYING_PAUSED,
      FAKE_SINK_STATE_ERROR_PAUSED_READY,
      FAKE_SINK_STATE_ERROR_READY_NULL
    } GstFakeSinkStateError;

Possible state change errors for the state-error property.

`FAKE_SINK_STATE_ERROR_NONE` | no error
`FAKE_SINK_STATE_ERROR_NULL_READY` | cause the NULL to READY state change to fail
`FAKE_SINK_STATE_ERROR_READY_PAUSED` | cause the READY to PAUSED state change to fail:
`FAKE_SINK_STATE_ERROR_PAUSED_PLAYING` | cause the PAUSED to PLAYING state change to fail:
`FAKE_SINK_STATE_ERROR_PLAYING_PAUSED` | cause the PLAYING to PAUSED state change to fail:
`FAKE_SINK_STATE_ERROR_PAUSED_READY` | cause the PAUSED to READY state change to fail:
`FAKE_SINK_STATE_ERROR_READY_NULL` | cause the READY to NULL state change to fail:

## Signal Details

### The `"handoff"` signal

    void                user_function                      (GstFakeSink *fakesink,
                                                            GstBuffer   *buffer,
                                                            GstPad      *pad,

This signal gets emitted before unreffing the buffer.

`fakesink` : | the fakesink instance
`buffer` : | the buffer that just has been received
`pad` : | the pad that received it
`user_data` : | user data set when the signal handler was connected.

### The `"preroll-handoff"` signal

    void                user_function                      (GstFakeSink *fakesink,
                                                            GstBuffer   *buffer,
                                                            GstPad      *pad,
                                                            gpointer     user_data)      : Run Last

This signal gets emitted before unreffing the buffer.

`fakesink` : | the fakesink instance
`buffer` : | the buffer that just has been received
`pad` : | the pad that received it
`user_data` : | user data set when the signal handler was connected.
