    Hi,<br>
    <br>
    i want to analyze the audio that i received from the link...
    recording is not an options since it introduces transcoding in fs.&nbsp;
    <br>
    <br>
    I do this method for all other codecs like g722, g729, (PCMU/A not
    need wireshark can play it or you can save as .au), i get the all
    the rtp pkt and convert then with fs_encode to wav to reproduce with
    normal player.<br>
    <br>
    Bur for opus i can't figure out how to make it work... i already try
    to pass the fmtp args negotiated in the sdp with no luck..<br>
    <br>

&gt;Hi,
&gt;
&gt;i'm trying to get rtp opus to a wav file using fs_encode but is not 
&gt;working... anyone have tried to decode rtp with opus? can it be done 
&gt;with fs_encode?
&gt;
&gt;
&gt;So for what i did was:
&gt;
&gt;- wireshark -&gt; rtp streams -&gt; save as raw format
&gt;- fs_encode -v -l mod_opus 0x60f26a47.opus audio.wav
&gt;
&gt;
&gt;fs_encode creates the audio.wav but is empty.. i've done this with g729 
&gt;files but with opus is not working...
&gt;
&gt;
&gt;You can check the output of the command in 
&gt;<a class="moz-txt-link-freetext" href="https://pastebin.freeswitch.org/view/9cedcf56">https://pastebin.freeswitch.org/view/9cedcf56</a>

&gt;Thanks for the help.
