            "in": 0,
            "out": 647.68,
            "duration": 647.68,
            "source": "/Media/clip1.mp4"
        }, {

            "duration": 149,
            "source": "/Media/clip2.mp4"
        }, {
            "in": 0,

            "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

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!
