update Red5 webapp

config/avalon.yml

In avalon.yml, under streaming, change "url_handler:" to "server:". 

Add under streaming: "content_path:" and then the path to your rtmp stream folder.

It should look something like this:

  streaming:
    server: :adobe
    content_path: /var/avalon/rtmp_streams
    stream_token_ttl: 20
    rtmp_base: rtmp://mallorn.dlib.indiana.edu/avalon
    http_base: http://mallorn.dlib.indiana.edu/avalon

config/controlled_vocabulary.yml

Additional controlled vocabularies are required for Avalon 4. Merge the new version of config/controlled_vocabulary.yml.example with your customizations in config/controlled_vocabulary.yml.
