#!/usr/bin/env python2 # rtmpdump parameter generator for justin.tv/twitch.tv streams v4 # * Usage: jtvrtmp.py channelname [quality] # where channelname is the channel name ([twitch/justin].tv/channelname) # and quality is an optional parameter with a valid quality setting # (360p, 480p, 720p, etc) If quality isn't present, it selects 360p. # * if quality is live, it picks the quality setting with a +, which # is a restream of the video being sent to jtv, no transcoding involved. # # Changelog: # v4: Add shebang line # v3: Removed unicode copyright symbol # v2: Added exception catching for when a stream is offline or the specified # quality setting is unavailable. # v1: Initial release # # Copyright 2013 Steven Smith (blha303).
