Hello everybody,
I wanna listen a voice file being played in a channel from another channel that I am currently connected to after calling.
Is it possible?
If possible how can I do this? which function should I use and in which order?
ok I have done that. But a problem occurs. I am listening the voice or background music and accordingly I am singing.But the dx_mreciottdata which is supposed to record from two timeslots is recording from only my channel where i am singing. it is not recording from both channels. the recorded file consists only my song ..no backgound music........I have used the following code
int VoiceChannel::karaoke(char* filename){ printf("\n Entering karaoke"); int recfh; SC_TSINFO tsinfo11,tsinfo1,tsinfo22 ,tsinfo2, tsinfo; long scts1,scts11,scts22,scts2; long tslots[2]; DX_IOTT iott[1]; DV_TPT tpt; int ret; GC_INFO error; char devname1[140]=""; DX_XPB xpb_wav = { FILE_FORMAT_WAVE, DATA_FORMAT_PCM, DRT_11KHZ, 8 }; /* seek to the end of the file and record message */#ifdef _WIN32 if ( ( recfh = dx_fileopen( filename, O_RDWR | O_TRUNC | O_CREAT, 0666 ) )#else /* !_WIN32 */ if ( (recfh = open(filename, O_RDWR | O_TRUNC | O_CREAT, 0666))#endif /* _WIN32 */ == -1) { printf("Error opening file %s\n","record"); return(-1); } /* * Clear and Set-Up the IOTT strcuture */ tsinfo11.sc_numts = 1; tsinfo11.sc_tsarrayp = &scts11; dx_getxmitslot(voiceh,&tsinfo11); tsinfo1.sc_numts = 1; tsinfo1.sc_tsarrayp = &scts1; ret = gc_GetXmitSlot(ldev, &tsinfo1); if (ret != GC_SUCCESS) { gc_ErrorInfo(&error); printf("\n ErrorInfo == %s",error.gcMsg ); return (-1); } tsinfo22.sc_numts = 1; tsinfo22.sc_tsarrayp = &scts22; dx_getxmitslot(voiceh1,&tsinfo22); tsinfo2.sc_numts = 1; tsinfo2.sc_tsarrayp = &scts2; ret = gc_GetXmitSlot(ldev1, &tsinfo2); if (ret != GC_SUCCESS) { gc_ErrorInfo(&error); return (-1); } tslots[0] = scts1; tslots[1] = scts2; tsinfo.sc_numts = 2; tsinfo.sc_tsarrayp = &tslots[0]; //memset( iott, 0, sizeof( DX_IOTT ) ); iott[ 0 ].io_type = IO_DEV | IO_EOT; iott[ 0 ].io_fhandle = recfh; iott[0].io_offset = 0; iott[0].io_length = -1; iott[0].io_offset = IO_EOT; /* * Clear and then Set the DV_TPT structures */ //memset( tpt, 0, (sizeof( DV_TPT ) * 3) ); /* Terminate Record on Receiving any DTMF tone */ dx_clrtpt (&tpt,1); tpt.tp_type = IO_EOT; tpt.tp_termno = DX_MAXDTMF; tpt.tp_length = 1; tpt.tp_flags = TF_MAXDTMF; tpt.tp_nextp = NULL; if(dx_listen(voiceh,&tsinfo2) == -1) printf("\n ..............dx_listen failed.............."); else printf("\n ..............dx_listen Success.............."); if((gc_Listen(ldev, &tsinfo22, EV_SYNC) == -1)) printf("\n gc_Listen failed........ "); else printf("\n gc_Listen success........ ");
// Recording starts from voiceh(the called channel where caller will sing) and from voiceh1 where a background music is being played. But the function is recording only my song no background music.// ret = dx_mreciottdata(voiceh, &iott[0], &tpt, &xpb_wav, RM_TONE, &tsinfo); //ret = dx_mreciottdata(voiceh, &iott[0], &tpt, &xpb_wav, (unsigned short)(RM_TONE|EV_SYNC), &tsinfo); //dx_reciottdata(voiceh2, &iott[0], &tpt, &xpb_wav, PM_TONE | EV_ASYNC); if(ret == 0) { printf("////////////dx_mreciottdata success/////////////"); return(0); } else { printf("\n///////////dx_mreciottdata failed/////////////"); printf("\n Error = %s",ATDV_ERRMSGP(voiceh)); return(-1); } }
What can I do?
