Greeting,
I am making a pjsip sip application that is require to accept a call , then play a media file
I use? pjmedia_wav_player_port_create, pjmedia_snd_port_create_player, pjmedia_snd_port_connect,? to play a sound file
I call the pjsip from a linphone application, the call is answer and the File is played, (not on Linphone but from pjsip console application)
How I can play the sound file on the linphone device ?
Here is the code I used to play the file :
??? ??? ??? ??? pjmedia_session_info sess_info;
??? ??? ??? ??? const pjmedia_sdp_session *local_sdp;
??? ??? ??? ??? const pjmedia_sdp_session *remote_sdp;
??? ??? ??? ??? pjmedia_port *media_port;
??? ??? ??? ??? if (status_from_media != PJ_SUCCESS) {
??? ??? ??? ??? app_perror(THIS_FILE, "SDP negotiation has failed", status);
??? ??? ??? ??? /* Here we should disconnect call if we're not in the middle
??? ??? ??? ??? ?* of initializing an UAS dialog and if this is not a re-INVITE.
??? ??? ??? ??? ?*/
??? ??? ??? ??? return 0;
??? ??? ??? ??? }
??? ??? ??? ??? /* Get local and remote SDP.
??? ??? ??? ???? * We need both SDPs to create a media session.
??? ??? ??? ???? */
??? ??? ??? ??? status_from_media = pjmedia_sdp_neg_get_active_local(inv_from_media->neg, &local_sdp);
??? ??? ??? ??? status_from_media = pjmedia_sdp_neg_get_active_remote(inv_from_media->neg, &remote_sdp);
??? ??? ??? ??? /* Create session info based on the two SDPs.
??? ??? ??? ???? * We only support one stream per session for now.
??? ??? ??? ???? */
??? ??? ??? ??? status_from_media = pjmedia_session_info_from_sdp(inv_from_media->dlg->pool, g_med_endpt,
??? ??? ??? ??? ??? ??? ??? ??? ?? 1, &sess_info,

??? ??? ??? ??? if (status_from_media != PJ_SUCCESS) {
??? ??? ??? ??? app_perror( THIS_FILE, "Unable to create media session", status);
??? ??? ??? ??? return 0;
??? ??? ??? ??? }
??? ??? ??? ??? /* If required, we can also change some settings in the session info,
??? ??? ??? ???? * (such as jitter buffer settings, codec settings, etc) before we
??? ??? ??? ???? * create the session.
??? ??? ??? ???? */
??? ??? ??? ??? /* Create new media session, passing the two SDPs, and also the
??? ??? ??? ???? * media socket that we created earlier.
??? ??? ??? ???? * The media session is active immediately.
??? ??? ??? ???? */
