RTP padding bit

[Rafael Maia]

Hello,

Is the padding bit 'P' of the RTP being processed anywhere?



I cannot find any place where it is being processed. I have added this in :



PJ_DEF(pj_status_t) pjmedia_rtp_decode_rtp( pjmedia_rtp_session *ses,

const void *pkt, int pkt_len,

const pjmedia_rtp_hdr **hdr,

const void **payload,

unsigned *payloadlen)

{



/*.*/



/* Find and set payload. */

*payload = ((pj_uint8_t*)pkt) + offset;

*payloadlen = pkt_len - offset;



/* the padding bit is set. lets remove a few octetcs from the payload
len */

if ((*hdr)->p) {

*payloadlen -= ((unsigned char* )(*payload))[*payloadlen - 1];

}



return PJ_SUCCESS;

}



Does anyone know where should it be processed when sending RTP packets ?

I was thinks in doing in this method: pjmedia_transport_send_rtp. Before the
(*tp->op->send_rtp) is called.

Any suggestions?



Cheers,

Rafael Maia

Hi,

You may be right. I just added
https://trac.pjsip.org/repos/ticket/1135 to check this further.

Best regards,
