### GST_RTP_VERSION

    #define GST_RTP_VERSION 2

The supported RTP version 2.

### gst_rtp_buffer_allocate_data ()

    void                gst_rtp_buffer_allocate_data        (GstBuffer *buffer,
                                                             guint payload_len,
                                                             guint8 pad_len,

Allocate enough data in `buffer` to hold an RTP packet with `csrc_count` CSRCs, a payload length of `payload_len` and padding of `pad_len`. MALLOCDATA of `buffer` will be overwritten and will not be freed. All other RTP header fields will be set to 0/FALSE.

`buffer` : | a GstBuffer
`payload_len` : | the length of the payload
`pad_len` : | the amount of padding
`csrc_count` : | the number of CSRC entries

### gst_rtp_buffer_new_take_data ()

    GstBuffer*          gst_rtp_buffer_new_take_data        (gpointer data,
                                                             guint len);

Create a new buffer and set the data and size of the buffer to `data` and `len` respectively. `data` will be freed when the buffer is unreffed, so this function transfers ownership of `data` to the new buffer.

`data` : | data for the new buffer
`len` : | the length of data
Returns : | A newly allocated buffer with `data` and of size `len`.

### gst_rtp_buffer_new_copy_data ()

    GstBuffer*          gst_rtp_buffer_new_copy_data        (gpointer data,
                                                             guint len);

Create a new buffer and set the data to a copy of `len` bytes of `data` and the size to `len`. The data will be freed when the buffer is freed.

`data` : | data for the new buffer
`len` : | the length of data
Returns : | A newly allocated buffer with a copy of `data` and of size `len`.

### gst_rtp_buffer_new_allocate ()

    GstBuffer*          gst_rtp_buffer_new_allocate         (guint payload_len,
                                                             guint8 pad_len,
                                                             guint8 csrc_count);

Allocate a new Gstbuffer with enough data to hold an RTP packet with `csrc_count` CSRCs, a payload length of `payload_len` and padding of `pad_len`. All other RTP header fields will be set to 0/FALSE.

`payload_len` : | the length of the payload
`pad_len` : | the amount of padding
`csrc_count` : | the number of CSRC entries
Returns : | A newly allocated buffer that can hold an RTP packet with given parameters.

### gst_rtp_buffer_new_allocate_len ()

    GstBuffer*          gst_rtp_buffer_new_allocate_len     (guint packet_len,
                                                             guint8 pad_len,
                                                             guint8 csrc_count);

Create a new GstBuffer that can hold an RTP packet that is exactly `packet_len` long. The length of the payload depends on `pad_len` and `csrc_count` and can be calculated with `gst_rtp_buffer_calc_payload_len()`. All RTP header fields will be set to 0/FALSE.

`packet_len` : | the total length of the packet
`pad_len` : | the amount of padding
`csrc_count` : | the number of CSRC entries
Returns : | A newly allocated buffer that can hold an RTP packet of `packet_len`.

### gst_rtp_buffer_calc_header_len ()

    guint               gst_rtp_buffer_calc_header_len      (guint8 csrc_count);

Calculate the header length of an RTP packet with `csrc_count` CSRC entries. An RTP packet can have at most 15 CSRC entries.

`csrc_count` : | the number of CSRC entries
Returns : | The length of an RTP header with `csrc_count` CSRC entries.

### gst_rtp_buffer_calc_packet_len ()

    guint               gst_rtp_buffer_calc_packet_len      (guint payload_len,
                                                             guint8 pad_len,

Calculate the total length of an RTP packet with a payload size of `payload_len`, a padding of `pad_len` and a `csrc_count` CSRC entries.

`payload_len` : | the length of the payload
`pad_len` : | the amount of padding
`csrc_count` : | the number of CSRC entries
Returns : | The total length of an RTP header with given parameters.

### gst_rtp_buffer_calc_payload_len ()

    guint               gst_rtp_buffer_calc_payload_len     (guint packet_len,
                                                             guint8 pad_len,
                                                             guint8 csrc_count);

Calculate the length of the payload of an RTP packet with size `packet_len`, a padding of `pad_len` and a `csrc_count` CSRC entries.

`packet_len` : | the length of the total RTP packet
`pad_len` : | the amount of padding
`csrc_count` : | the number of CSRC entries
Returns : | The length of the payload of an RTP packet with given parameters.

### gst_rtp_buffer_validate ()

    gboolean            gst_rtp_buffer_validate             (GstBuffer *buffer);

Check if the data pointed to by `buffer` is a valid RTP packet using `validate_data()`. Use this function to validate a packet before using the other functions in this module.

`buffer` : | the buffer to validate
Returns : | TRUE if `buffer` is a valid RTP packet.

### gst_rtp_buffer_validate_data ()

    gboolean            gst_rtp_buffer_validate_data        (guint8 *data,
                                                             guint len);

Check if the `data` and `size` point to the data of a valid RTP packet. This function checks the length, version and padding of the packet data. Use this function to validate a packet before using the other functions in this module.

`len` : | the length of `data` to validate
Returns : | TRUE if the data points to a valid RTP packet.

### gst_rtp_buffer_set_packet_len ()

    void                gst_rtp_buffer_set_packet_len       (GstBuffer *buffer,
