You should use a “SimpleRTPSink” - specifically:</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>
SimpleRTPSink::createNew(envir(), rtpGroupsock,<br class="">
rtpPayloadTypeIfDynamic,
16000,<br class="">
"audio", “L16",
numChannels);</div>
<div>where “numChannels” is 1 for mono, and 2 for stereo.</div>
<div><br class="">
</div>
<div>Note, however, that because your input source is in
‘little-endian’ form (I presume that’s what the “LE” stands
for), you will need to byte-swap it before you feed it into your
“SimpleRTPSink” (because the IETF standard RTP payload format
for the “audio/L16” type specifies that the data be packed into
RTP packets in big-endian form.</div>
<div><br class="">
</div>
<div>Therefore, your implementation of the
“createNewStreamSource()” virtual function should feed the input
source into a new “EndianSwap16” filter object (and return a
pointer to that filter object).</div>
