notes and other info

  • 4 HD streams were too heavy for my dual core hyperthreaded 2.4GHz laptop: it would glitch into an unintelligible paint blob
  • using a VLM config file to open multiple streams with bandwith/cpu issues causes all streams to pause upon reconnecting a stream that went out of sync. Use a separate instance for each stream
  • the RTP stream seems to emit some type of timecode, so multiple streams are fairly in sync. Picking up on the RTP streams to create an RTP mosaic will off course delay that mosaic
  • In 2013, Xopr wrote an XBMC remote control script for streams to switch channels from within a console with just one keypress.
  • Multicast streams didn't work on wifi (as expected), but even worse: multicast broke the wifi networks

audio streams (phone)

Currently, due to our temporary setup of the VoIP system, nothing has been set-up to listen to the streams via the phone. Focus is on the #video streams for now.

If you want to help out and fix the phone streaming, contact xopr.
