Re: [Linphone-users] ORTP - I have a problem with rtp_session_recv_with_ts() fucntion

[Simon Morlat]

Actually this function returns 0 when no packet have been received yet. When 
the stream has started, and if the stream is G711 (pcma or pcmu) this 
function fills unreceived packets with silence data (it emulates 
untransmitted packets by returning silence buffers), thus it never returns 0.
If you are borried by this behaviour, use the rtp_session_recvm_with_ts() 
function that returns 'raw' packet directly.
