JSON Playlist Example

{
    "channel": "Test 1",
    "date": "2019-03-05",
    "program": [{
            "in": 0,
            "out": 647.68,
            "duration": 647.68,
            "source": "/Media/clip1.mp4"
        }, {
            "in": 0,
            "out": 149,
            "duration": 149,
            "source": "/Media/clip2.mp4"
        }, {
            "in": 0,
            "out": 114.72,
            "duration": 114.72,
            "source": "/Media/clip3.mp4",
            "category": "advertisement"
        }, {
            "in": 0,
            "out": 2531.36,
            "duration": 2531.36,
            "source": "/Media/clip4.mp4",
            "category": ""
        }
    ]
}

If you need a simple playlist generator check: playlist-generator

The playlist can be extend, to use custom attributes in your filters.

Warning

(Endless) streaming over multiple days will only work when config have day_start value and the length value is 24 hours. If you need only some hours for every day, use a cron job, or something similar.

Remote source from URL

You can use sources from remote URL in that way:

...
        {
            "in": 0,
            "out": 149,
            "duration": 149,
            "source": "https://example.org/big_buck_bunny.webm"
        }

But be careful with it, better test it multiple times!

Installation

Check INSTALL.md

Start with Arguments

ffplayout also allows the passing of parameters:

  • -c, --config use given config file
  • -f, --folder use folder for playing
  • -l, --log for user-defined log path, none for console output
  • -i, --loop loop playlist infinitely
  • -m, --mode set output mode: desktop, hls, stream, ...
  • -p, --playlist for playlist file
  • -s, --start set start time in hh:mm:ss, now for start with first
  • -t, --length set length in hh:mm:ss, none for no length check

You can run the command like:

./ffplayout.py -l none -p ~/playlist.json -d -s now -t none -m desktop

Multi Channel

For streaming multiple channels you need to use python supervisorD. A systemd service for it you found in docs folder.

To configure every channel create your ffplayout yaml configs under /etc/ffplayout with naming them ffplayout-001.yml, ffplayout-002.yml and so on. Then copy and edit the supervisor config /supervisor/conf.d/engine-001.conf with the same numbering.
