Once in a while I am watching sports on tv, and sometimes I am missing it. So luckily there are some streams available, but their players mostly suck on linux. So does sportschau.de in my chromium with flash installed. youtube actually works.
So this video looks like this on the source code, which is pretty awesome to build an rtmp url from.
Combine the 2 strings into one url and copy paste it into VLC and start the video.
Not that easy, but still better than those sucky embedded players. Especially since you can rtmpdump these streams then too. Still, that one could be illegal, so check on that first.
# rtmpdump -r "<URL>" -o filename.mp4
