normal system requirements and no special tools

JSON Playlist Example

{
    "channel": "Test 1",
    "date": "2019-03-05",
    "begin": "06:00:00.000",
    "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": ""
        }
    ]
}

"begin" and "length" are optional, when you leave begin blank, length check will be ignored and the playlist starts from the begin, without time awareness. If you leave length blank, the validation will not check if the real length of the playlist will match the length value.

Warning:

(Endless) streaming over multiple days will only work when the playlist have both keys and the length 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!
