ffplayout

This is a streaming solution based on python and ffmpeg.

The goal is to play for every day an xml playlist, while the current playlist is still editable.

Features

  • have all values in a separate config file
  • try to be as simple as possible
  • dynamic playlist
  • replace missing playlist or clip with a blank clip
  • send emails with error message
  • overlay a logo
  • trim and fade the last clip, to get full 24 hours, if the duration is less then 6 seconds add a blank clip
  • set custom day start, so you can have playlist for example: from 6am to 6am, instate of 0am to 12pm
  • normal system requirements and no special tools
    • we only need ffmpeg, ffprobe and a buffer tool like mbuffer or pv
    • no GPU power is needed
    • ram and cpu depends on video resolution, minimum 4 threads and 3GB ram for 720p are recommend
  • python version 3.5 and up
