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": ""
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
**If you need a simple playlist generator check:** [playlist-generator](https://github.com/ffplayout/playlist-generator)
|
|
|
|
The playlist can be extend, to use custom attributes in your [filters](/ffplayout/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:
|
|
|
|
```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!
|
|

|
- `-m, --mode` set output mode: **desktop**, **hls**, **stream**, ...
|
|

```

|
|
Multi Channel
|
|
-----
|
|
|
|
For streaming multiple channels you need to use python supervisorD. A systemd [service](/docs/ffplayout-engine-multichannel.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](/supervisor/conf.d/engine-001.conf) with the same numbering.
