[Linphone-developers] oRTP using for dynamic sessions pool

[Oleksii Vynogradov]

Hi

i try to using oRTP, and i have dynamic adding sessions to play same file at runtime.

For that, i'm using that code:

        while (1) {

            while( ((i=(int)fread(buffer,1,packet_size,infile))>0))

            {

                NSMutableArray *currentRtpSessionsPCMU = nil;

                @synchronized (self.rtpSessionsPCMU) {

                    currentRtpSessionsPCMU = self.rtpSessionsPCMU;

                }

                if (currentRtpSessionsPCMU.count > 0) {

                    [currentRtpSessionsPCMU enumerateObjectsUsingBlock:^(NSDictionary *rtpSession, NSUInteger idx, BOOL *stop) {

                        NSNumber *rtpSessionIndex = [rtpSession valueForKey:@"rtpSessionIndex"];

                        session_set_set(set,sessions[rtpSessionIndex.intValue]);

                    }];

                    /* and then suspend the process by selecting() */

                    session_set_select(NULL,set,NULL);

                    [currentRtpSessionsPCMU enumerateObjectsUsingBlock:^(NSDictionary *rtpSession, NSUInteger idx, BOOL *stop) {

                        NSNumber *rtpSessionIndex = [rtpSession valueForKey:@"rtpSessionIndex"];

                        if (session_set_is_set(set,sessions[rtpSessionIndex.intValue])){

                            rtp_session_send_with_ts(sessions[rtpSessionIndex.intValue],buffer,i,user_ts);

                            //ortp_message("packet sended !");

                        }

                    }];

                }

                user_ts+=ts_inc;

            }

            fclose(infile);

            //NSLog(@"close file RTP_RING_PCMU");

            sleep(1);

            infile=fopen([finalPath UTF8String],"rb");

        }

everything working fine until i adding new session. in rtpSessionsPCMU array

second receiver don't receive nothing

i was try to close file and open again, but second receiver receive only small part of record and than don't hear nothing.

if i try to set 0 user_ts and clear buffer after close and open file, it second receiver don't receive nothing.

can you suggest peace of code to add dynamically new sessions and play same file to there? In mrtpsend all sessions created from start, in my case sessions will added and closed 

while file it going to play.

Tnx,
