The RTMP dissector does not know the audio codec used in the attached capture
file.
See Frame 47: Control: 0xaf (Unknown codec 44 kHz 16 bit stereo).
The Wireshark source file epan\dissectors\packet-rtmpt.c, variable
rtmpt_audio_codecs should be enhanced.
According to
http://help.adobe.com/en_US/FlashMediaServer/3.5_Deving/WS5b3ccc516d4fbf351e63e3d11a0773d56e-7ff6.html
10 = HE-AAC and 11 = Speex are missing.
There is also
http://www.adobe.com/content/dam/Adobe/en/devnet/rtmp/pdf/rtmp_specification_1.0.pdf,
page 47, which additionally lists 3 = INTEL (not used), 7 = G711A, 8 = G711U
and 9 = NellyMoser 16kHz.
This PDF document also lists additional video codecs (variable
rtmpt_video_codecs):
0 = unused (obsolete) and 1 = JPEG (obsolete) but I'm not sure if it is worth
adding these.
