#!/usr/bin/env python2 # rtmpdump parameter generator for justin.tv/twitch.tv streams v5 # * 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 'live'. # * 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: # v5: Changed to default to 'live' quality instead of 360p, as some streams # don't have 360p transcoding; made the code in main() slightly cleaner, # possibly shorter. # 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).
