Hi,
Building Wireshark from the latest source, I've noticed a small issue related to the dissection of RTP packets.
A generic RTP PCMU (pt=0) packet is decoded as a malformed RTP-MIDI packet. The problem is the default payload type assigned to the RTP-MIDI packets is set to 0, which is just an oversight, I believe. It should be in the range of dynamic payload types such as 96-127. Changing that value from the Preferences helps. However, you may want to change the default value in the code too.
