channel.addchannel

This API creates a Playlist of live streams and/or VOD files to be played on a Channel at a scheduled time. The playlist can be configured to play through its list once, or to loop continuously.

DVR applications additionally can set the # of chunks to keep in their playlist and how long to keep the dvr session alive by providing a 'playlist_count' and 'playlist_timeout' or disable dvr using 'enable_dvr'. To edit the dvr settings see stream.dvrsettings api.

You can track viewer session data on your channel from Google Analytics (GA) by providing your GA key. When creating or updating a playlist, all playlists on the same channel will have their GA keys updated.
