JSON Playlist Example
|
|
-----
|
|
|
|
```json
|
|
{
|
|
"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": ""
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
#### 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:
|
|
|
|
```json
|
|
...
|
|
{
|
|
"in": 0,
|
|
"out": 149,
|
|
"duration": 149,
|
|
"source": "https://example.org/big_buck_bunny.webm"
|
|
}
|
|
```
|
|
But be careful with it, better test it multiple times!
