<p>NOTE: use of this function is discouraged when sending payloads other than pcm/pcmu/pcma/adpcm types. <a class="el" href="rtpsession_8h.html#a7df1261d3eeaf10d283ba4ac34e2388d">rtp_session_recvm_with_ts()</a> does better job.</p>
<p>Tries to read the bytes of the incoming rtp stream related to timestamp ts. In case where the user supplied buffer is not large enough to get all the data related to timestamp ts, then *( have_more) is set to 1 to indicate that the application should recall the function with the same timestamp to get more data.</p>
<p>When the rtp session is scheduled (see <a class="el" href="rtpsession_8h.html#a431c5b6dd2834bef90fef43bd643eb80">rtp_session_set_scheduling_mode()</a> ), and the blocking mode is on (see <a class="el" href="rtpsession_8h.html#a3160cbe78f10ac689845ed967b7cd974">rtp_session_set_blocking_mode()</a> ), then the calling thread is suspended until the timestamp given as argument expires, whatever a received packet fits the query or not.</p>
<p>Important note: it is clear that the application cannot know the timestamp of the first packet of the incoming stream, because it can be random. The timestamp given to the function is used relatively to first timestamp of the stream. In simple words, 0 is a good value to start calling this function.</p>
<p>This function internally calls <a class="el" href="rtpsession_8h.html#a7df1261d3eeaf10d283ba4ac34e2388d">rtp_session_recvm_with_ts()</a> to get a rtp packet. The content of this packet is then copied into the user supplied buffer in an intelligent manner: the function takes care of the size of the supplied buffer and the timestamp given in argument. Using this function it is possible to read continous audio data (e.g. pcma,pcmu...) with for example a standart buffer of size of 160 with timestamp incrementing by 160 while the incoming stream has a different packet size.</p>
<p>Returns: if a packet was availlable with the corresponding timestamp supplied in argument then the number of bytes written in the user supplied buffer is returned. If no packets are availlable, either because the sender has not started to send the stream, or either because silence packet are not transmitted, or either because the packet was lost during network transport, then the function returns zero. </p>

<p>Try to get a rtp packet presented as a mblk_t structure from the rtp session. The parameter is relative to the first timestamp of the incoming stream.

<p>This function returns the entire packet (with header).</p>
<p>The behaviour of this function has changed since version 0.15.0. Previously the payload data could be accessed using mblk_t::b_cont::b_rptr field of the returned mblk_t. This is no more the case. The convenient way of accessing the payload data is to use rtp_get_payload() : </p>

<p>This function provides the way for an application to be informed of various events that may occur during a rtp session. is a string identifying the event, and is a user supplied function in charge of processing it. The application can register several callbacks for the same signal, in the limit of RTP_CALLBACK_TABLE_MAX_ENTRIES. Here are name and meaning of supported signals types:</p>
<p>"ssrc_changed" : the SSRC of the incoming stream has changed.</p>
<p>"payload_type_changed" : the payload type of the incoming stream has changed.</p>
<p>"telephone-event_packet" : a telephone-event rtp packet (RFC2833) is received.</p>
<p>"telephone-event" : a telephone event has occured. This is a high-level shortcut for "telephone-event_packet".</p>
<p>"network_error" : a network error happened on a socket. Arguments of the callback functions are a const char * explaining the error, an int errno error code and the user_data as usual.</p>
<p>"timestamp_jump" : we have received a packet with timestamp in far future compared to last timestamp received. The farness of far future is set by rtp_sesssion_set_time_jump_limit() "rtcp_bye": we have received a RTCP bye packet. Arguments of the callback functions are a const char * containing the leaving reason and the user_data.</p>
