As stated a few messages above, those are rtmpdump errors (they are not related in any way to this script).

You can remove in models.py the "--quiet" parameter from the rtmpdump command line in order to see the errors in the log.

I really don't know how to correct those rtmpdump errors (they are "system" related as it works on some unbuntu installations but not on some others), feel free to post it there if you find some day.
