JSON Playlist Example

{
    "channel": "Test 1",
    "date": "2019-03-05",
    "length": "24:00:00.000",
    "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": ""
        }
    ]
}

"length" are optional, when you leave it blank, there will be no check if real playlist length is correct.

Warning:

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

Source from URL / Live Stream

You can use sources from url or live stream in that way:

...
        {
            "in": 0,
            "out": 149,
            "duration": 149,
            "source": "https://example.org/big_buck_bunny.webm"
        },
...
        {
            "in": 0,
            "out": 2531.36,
            "duration": 0,
            "source": "rtmp://example.org/live/stream"
        }
...

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