Getting wireshark to format OSC messages

mrreason · July 16, 2020, 8:21pm

I like to use this top for my osc/wireshark question, if that is ok.

My wireshark does not recognize my udp packets as osc packets. When I select an osc packet and want to set "Decode as", I can only select for tcp ports that it should decode the packets over the specific port (say 57120) as osc. For upd packets (and this is sent by Tidal), I can't choose to decode it as osc packets.

In general I see the packets (even if a bit cryptic):

I am using Wireshark 3.2.5 (current stable release) on macOS 10.15.5

I've never been able to figure out how to get Wireshark to work (and tried a few times) so thanks for posting here.

Yes @lwlsn was having problems with this too. I'm using wireshark 2.6.10 from linux mint and it works fine.

Maybe it needs to be enabled @mrreason ? https://www.wireshark.org/docs/wsug_html/#ChAdvEnabledProtocols

(Decided best to move to a new topic as it was a bit different from the print values to console one)

Thank you very much, this was the problem!

As you can see, osc_udp is disabled by default. After I enabled it, it works!

Now I can do fancy stuff like filtering and color marking (e.g. to distinguish between different ports)

Great! OSC is generally sent over UDP, so that's a strange thing to be off by default..
