Thanks, seems to work!
Just one approvement:
grep -E -o "rtmp:[^\"]+"
takes the first mentioned rtmp-URL, or am I wrong?
As I saw, there are often several rtmp-URLs with different qualities in the json, beginning with the lowest quality, ascending to the best one. So it would be better to take the last mentioned rtmp-URL.
Two examples I found:

Thanks for your work!
EDIT: Just saw: The order of the URLs can change. So you'll better look for the filename ending. My quick&dirty fix:
grep -E -o "rtmp:[^\"]+((q50.mp4)|(500k.flv))"
