f_rtp_create_pkt()

t_slv_arr f_rtp_create_pkt (   rtp_header in t_rtp_header ,   payload in t_slv_arr   )

Function

Create RTP packet.

Parameters

rtp_header	RTP header
payload	RTP payload

Returns

RTP packet (8bit array) or length of RTP packet

Create RTP packet. Payload must be 8bit data array.

Example use

v_rtp_header  := C_DEFAULT_RTP_HEADER;
v_packet_8bit := f_rtp_create_pkt(v_rtp_header, payload); 

f_rtp_create_pkt_len()

natural f_rtp_create_pkt_len (   rtp_header in t_rtp_header ,   payload in t_slv_arr   )

Function

Return length of RTP packet.

Parameters

rtp_header	RTP header
payload	RTP payload

Returns

Length of RTP packet

Return the length of the created RTP packet.

Example use

v_len                      := f_rtp_create_pkt_len(v_rtp_header, payload); 
v_pkt_8bit(0 to v_len - 1) := f_rtp_create_pkt(v_rtp_header, payload);

f_rtp_get_header()

t_rtp_header f_rtp_get_header (   rtp_pkt in t_slv_arr   )

Function

Get RTP header.

Parameters

rtp_pkt

RTP packet (8bit)

Returns

RTP header

Extract RTP header from RTP packet.

Example use

v_rtp_header := f_rtp_get_header(data_array_8bit); 

f_rtp_get_payload()

t_slv_arr f_rtp_get_payload (   rtp_pkt in t_slv_arr   )

Function

Get RTP payload.

Parameters

rtp_pkt

RTP packet (8bit)

Returns

t_slv_arr

Extract RTP payload from RTP packet (including extension header and padding if present).

Example use

v_len                     := f_rtp_get_payload_len(data_array_8bit); 
v_payload(0 to v_len - 1) := f_rtp_get_payload(data_array_8bit); 

f_rtp_get_payload_len()

natural f_rtp_get_payload_len (   rtp_pkt in t_slv_arr   )

Function

Get RTP payload length.

Parameters

rtp_pkt

RTP packet (8bit)

Returns

RTP payload length

Get RTP payload length from RTP packet (including extension header and padding if present).

Example use

v_len := f_rtp_get_payload_len(data_array_8bit); -- determine size of payload
