Streams won't launch

[Poorchop]

I can navigate through lists of the streams but streams won't launch when they are selected. I get the following error:

Traceback (most recent call last):
  File "lol.py", line 207, in <module>
    main()
  File "lol.py", line 202, in main
    subprocess.call("livestreamer " + "twitch.tv/" + chosen_stream + " best")
  File "/usr/lib64/python2.7/subprocess.py", line 524, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.7/subprocess.py", line 1308, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Steps to replicate:

• python lol.py
• 1 (to select games)
• 1 (to select Dota in this case)
• try selecting any of the 10 streams listed

In addition, when I try to select featured streams instead, I get a list of the 10 featured streams followed by this error:

Traceback (most recent call last):
  File "lol.py", line 207, in <module>
    main()
  File "lol.py", line 202, in main
    subprocess.call("livestreamer " + "twitch.tv/" + chosen_stream + " best")
UnboundLocalError: local variable 'chosen_stream' referenced before assignment

Hi, thanks for finding the bug. I just pushed an initial fix for both the things that you pointed out. Let me know if it works.

Featured streams now work properly, but there is a new error when I try to navigate to the live Dota 2 streams:

  File "lol.py", line 210, in <module>
    main()
  File "lol.py", line 186, in main
    parser.print_streams()
  File "lol.py", line 72, in print_streams
    status = stream["channel"]["status"].encode('ascii', 'ignore')
AttributeError: 'NoneType' object has no attribute 'encode'

Right now, this seems like it's only happening only with Dota 2. I was able to navigate to and launch League of Legends, Starcraft II, Dark Souls, and Minecraft streams without any issues. When I try to view Dota streams, only 0-6 or 0-7 are listed, immediately followed by the error message. Maybe something is wrong with the twitch API.

figured out the issue: one of the top streamers has no status that, when parsed as json, is a null rather than an empty string. fixed it, and it runs correctly on my system now. thanks for helping me find the bug!
