    comment: "This flowgraph can be adapted to watch the stream live by\ninstalling\
      \ gr-grnet and using a tcp sink in \"server\" mode.\nYou can then use smplayer\
      \ to play the stream (vlc doesn't\nwork as well as it doesn't seem to tolerate\
      \ stream errors\nwell.  In smplayer, under options these non-default settings\n\
      seemed to help with stream viewing:\n- set performance preferences to allow\
      \ \n  frame drops and hard frame drops.\n- Set hardware decoding to auto.\n\
      - On the cache performance tab Increase stream buffer to 8096.\n\nNOTE: Be patient\
      \ with the players if there's errors in the signal.\nOn a real TV it may pixelate,\
      \ but with streaming players they may\nget out of sync and look like they freeze\
      \ with no video while \nthey're trying to resync with good data."
