You meant to multicast in L16 format so that listener will not require to do anything for coding/decoding, right?<br><br><div class="gmail_quote">On Tue, Feb 23, 2010 at 11:13 PM, Anthony Minessale <span dir="ltr"><<a href="mailto:anthony.minessale@gmail.com">anthony.minessale@gmail.com</a>></span> wrote:<br>

Your only other option is to use L16 (raw signed linear)<br> <br><br><div class="gmail_quote"><div><div></div><div>On Mon, Feb 22, 2010 at 5:53 AM, MohammedShehzad <span dir="ltr"><<a href="mailto:pmhshz@gmail.com" target="_blank">pmhshz@gmail.com</a>></span> wrote:<br>

<action application="playback" data="rtp://<a href="http://224.168.168.168:34567" target="_blank">224.168.168.168:34567</a>"/><br>
Please see on thread named 'stream a file multicast with mod_esf' on <a href="http://lists.freeswitch.org/pipermail/freeswitch-users/2010-February/026163.html" target="_blank">http://lists.freeswitch.org/pipermail/freeswitch-users/2010-February/026163.html</a><br>
<br>I am testing that module against the audio multicasted by mod_esf module.<br>I got some success with help of existing mod_native_file module, and I able to receive and play the multicasted RAW PCMU RTP (modified the
skel of format module provided by brian), so that caller can hear the
multicast by other Freeswitch server, but when i change the caller's codec from PCMU to something
else, it breaks.<br>Then I looked into mod_sndfile for decoding PCMU to other codec, but it seems
that module is using libsndfile, which reads sound file directly and
decode them to L16. If something similar to libsndfile is available,
which work on stream instead of reading file, then it would surely work.<br>Please Let me know your ideas on this, as I don't know how exactly Freeswitch encoding-decoding works?<br><br>-- <br><font color="#888888"><br>
