Control the buffering algorithm in use.

Default value: Slave receiver to sender clock

### The `"percent"` property

      "percent"                  gint                  : Read

The buffer filled percent.

Allowed values: [0,100]

Default value: 0

## Signal Details

### The `"clear-pt-map"` signal

    void                user_function                      (GstRtpJitterBuffer *buffer,
                                                            gpointer            user_data)      : Action

Invalidate the clock-rate as obtained with the "request-pt-map" signal.

`buffer` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.

### The `"handle-sync"` signal

    void                user_function                      (GstRtpJitterBuffer *buffer,
                                                            GstStructure       *struct,
                                                            gpointer            user_data)      : Run Last

Be notified of new sync values.

`buffer` : | the object which received the signal
`struct` : | a GstStructure containing sync values.
`user_data` : | user data set when the signal handler was connected.

### The `"on-npt-stop"` signal

    void                user_function                      (GstRtpJitterBuffer *buffer,
                                                            gpointer            user_data)      : Run Last

Signal that the jitterbufer has pushed the RTP packet that corresponds to the npt-stop position.

`buffer` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.

### The `"request-pt-map"` signal

    GstCaps*            user_function                      (GstRtpJitterBuffer *buffer,
                                                            guint               pt,
                                                            gpointer            user_data)      : Run Last

Request the payload type as GstCaps for `pt`.

`buffer` : | the object which received the signal
`pt` : | the pt
`user_data` : | user data set when the signal handler was connected.

### The `"set-active"` signal

    guint64             user_function                      (GstRtpJitterBuffer *buffer,
                                                            gboolean            Returns,
                                                            guint64             arg2,
                                                            gpointer            user_data)      : Action

Start pushing out packets with the given base time. This signal is only useful in buffering mode.

`buffer` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.
Returns : | the time of the last pushed packet.
