#### process

    GstBuffer *
    process (GstRTPBaseDepayload * base,
             GstBuffer * in)

process incoming rtp packets. Subclass must implement either this method or process_rtp_packet to process incoming rtp packets. If the child returns a buffer without a valid timestamp, the timestamp of the provided buffer will be applied to the result buffer and the buffer will be pushed. If this function returns NULL, nothing is pushed.

Parameters:

`base` –
No description available
`in` –
No description available
Returns –
No description available

#### vfunc_process

    function vfunc_process(base: GstRtp.RTPBaseDepayload, in: Gst.Buffer): {
        // javascript implementation of the 'process' virtual method
    }

process incoming rtp packets. Subclass must implement either this method or process_rtp_packet to process incoming rtp packets. If the child returns a buffer without a valid timestamp, the timestamp of the provided buffer will be applied to the result buffer and the buffer will be pushed. If this function returns null, nothing is pushed.

Parameters:

`base` ( GstRtp.RTPBaseDepayload ) –
No description available
`in` ( Gst.Buffer ) –
No description available
Returns ( Gst.Buffer ) –
No description available

#### do_process

    def do_process (base, in):
        #python implementation of the 'process' virtual method

process incoming rtp packets. Subclass must implement either this method or process_rtp_packet to process incoming rtp packets. If the child returns a buffer without a valid timestamp, the timestamp of the provided buffer will be applied to the result buffer and the buffer will be pushed. If this function returns None, nothing is pushed.

Parameters:

`base` ( GstRtp.RTPBaseDepayload ) –
No description available
`in` ( Gst.Buffer ) –
No description available
Returns ( Gst.Buffer ) –
No description available

#### process_rtp_packet

    GstBuffer *
    process_rtp_packet (GstRTPBaseDepayload * base,
                        GstRTPBuffer * rtp_buffer)

Same as the process virtual function, but slightly more efficient, since it is passed the rtp buffer structure that has already been mapped (with GST_MAP_READ) by the base class and thus does not have to be mapped again by the subclass. Can be used by the subclass to process incoming rtp packets. If the subclass returns a buffer without a valid timestamp, the timestamp of the input buffer will be applied to the result buffer and the output buffer will be pushed out. If this function returns NULL, nothing is pushed out. Since: 1.6.

Parameters:

`base` –
No description available
`rtp_buffer` –
No description available
Returns –
No description available

#### vfunc_process_rtp_packet

        // javascript implementation of the 'process_rtp_packet' virtual method
    }

Same as the process virtual function, but slightly more efficient, since it is passed the rtp buffer structure that has already been mapped (with GST_MAP_READ) by the base class and thus does not have to be mapped again by the subclass. Can be used by the subclass to process incoming rtp packets. If the subclass returns a buffer without a valid timestamp, the timestamp of the input buffer will be applied to the result buffer and the output buffer will be pushed out.
