[Jack-Devel] AES67 / SMPTE ST 2110-30

[Christoph Kuhr]

Hi,

in january a master student is also starting to implement an open source 
  AES67 client in his thesis under my supervision.
Perhaps there are some topics to share and collaborate.
But some organizational issues need to be solved at the moment.


BR,
Christoph
