Hi all,
I am using ortp to send and receive audio packets bwtween my pc and
developing board. I have made oRTP work in schedule mode not in blocking
mode, the code is:
*mysession = rtp_session_new(RTP_SESSION_SENDRECV);*
* rtp_session_set_scheduling_mode(mysession, 1); *
* rtp_session_set_blocking_mode(mysession, 0);*
* rtp_session_enable_adaptive_jitter_compensation(mysession, TRUE);
rtp_session_set_recv_buf_size(mysession,1024);
rtp_session_set_local_addr(mysession, _localip, 10500);
rtp_session_set_remote_addr(mysession, remote_sdp_audio_ip,
remote_sdp_audio_port);
rtp_session_set_payload_type(mysession, payload);*
when receiving packets i use :
* SessionSet *recv_session_set;
recv_session_set = session_set_new();
session_set_set(recv_session_set, mysession);*
* *
* while(1)*
* {*
* ret = session_set_select(recv_session_set, NULL, NULL);
if((ret != -1) && session_set_is_set(recv_session_set, mysession))
{
i = rtp_session_recv_with_ts(mysession, data_in, length,
timestamp, &have_more); *
* if (i > 0)*
{
* // then i save the data_in to a file and do other
things.*
*timestamp += i;*
}
* *
* }*
* // do other thins*
* }*
when I send the packets I use *rtp_session_send_with_ts( ) *to send
packets directly. Both my board and pc work in the same way.
And the problem is, when I speak about 10s on the board side (i save my
voice to a file), and the pc side receive about 8s of my voice ( i also save
the packets received to a file).
According to reading the source code, I know in schedule mode (the
blocking mode is off), we can use *session_set_select* to block the thread
until the packet arrives, then we can use *rtp_session_recv_with_ts *to
receive packets.
But now, obviously there are some packets lost. In my program the packet
size is 320, and the timestamp is incresed by 320.
Would anyone please give me some advice to solve this problem?
Any other care needs to be taken.?
* *
By the way, when I set both blocking mode and schedule mode on, there are
more packets lost.
Thank you in advance!
