I'm sorry - but this is a local Dialect of German. I've been multiple times in Cologne, and this doesn't seem any different than the maybe 15 dialects that are spoken in Austria. 

Calling that a "language" is likely misleading. I'm not a linguist, though - but this is as much a "different language" to German as much as British Columbian English is a different language to English.
