[pjsip] pjusa-lib Can i set the sender ptime for G711 codec?

[hamstiede at yahoo.de]

Hi Gang,

i tried to set the codec parameter with this code, before i run pjsua_start()

pjmedia_codec_param* pCodecParam = 
    PJ_POOL_ZALLOC_T(m_pMemPool, struct pjmedia_codec_param);
    if (pjsua_codec_get_param(pj_cstr(&tmp, "pcma"),pCodecParam)==PJ_SUCCESS)
    {  pCodecParam->setting.frm_per_pkt=160;   
/*Number of frames per packet.*/
        pCodecParam->setting.vad=0;
        pCodecParam->setting.plc=0;
        pjsua_codec_set_param(pj_cstr(&tmp, "pcma"),pCodecParam);
    }


i increase the setting.frm_per_pkt to 320, maby this is like a  
ptime=40  ptime=ffp*1000/8000 for g711 but it doesn't work.
the pjmedia_codec_param struct has a info variable ptime but it is only info!!
 pCodecParam->info.frm_ptime;  

any idea ?

Did you try pjsua_codec_set_param() this function?

BTW, I didn't try it before.

Gang

Hello,
i want to set the ptime in pjsua-lib/application only in RTP sender direction.
Now it is fixed to the ptime default (20ms). I mean the RTP ptime for G711 codec,
not the conference ptime.


regards
  mark
