title: Tshark how to decode rtp.pt
body: <p>Could someone please help me on such topic.</p>
  <p>Trying to decode a network flow using tshark via:</p>
  <pre><code>tshark -r somefile.pcap -d rtp.pt==96,rtpeven
  </code></pre>
  <p>This results to a:</p>
  <blockquote>
  <p>tshark: Protocol &quot;rtpevent&quot; isn't valid for layer type &quot;rtp.pt&quot;</p>
  <p>tshark: Valid protocols for layer type &quot;rtp.pt&quot; are: (empty)</p>
  </blockquote>
  <p>Tried running on an old 1.12.7 wireshark version, and everything works file(has a wideload of available protocols).</p>
  <p>Thanks.</p>
