This is a playout application based on python and ffmpeg.

The purpose with ffplayout is to provide a 24/7 broadcasting solution that plays a *json* playlist for every day, while keeping the current playlist editable.

#### Check [ffplayout-gui](https://github.com/ffplayout/ffplayout-gui): web-based GUI for ffplayout.

Features and Requirements
-----

- have all values in a separate config file
- dynamic playlist
- replace missing playlist or clip with a dummy clip
- send emails with error message
- overlay a logo
- trim and fade the last clip, to get full 24 hours, if the duration is less then 6 seconds add a dummy clip
- set custom day start, so you can have playlist for example: from 6am to 6am, instate of 0am to 12pm
- copy mode, for more info's take a look in the [Wiki](https://github.com/ffplayout/ffplayout-engine/wiki/Copy-Mode)
- normal system requirements and no special tools
    - we only need **ffmpeg** and **ffprobe** (**ffplay** if you want to play on desktop)
    - no GPU power is needed
    - RAM and CPU depends on video resolution, minimum 4 threads and 3GB RAM for 720p are recommend
- python version 3.5 and up

#### Why not more features?
- ffplayout follows the principle: stability over features!
- ffplayout must be able to run in containers and VMs without problems, so it should be resource-efficient and not use GPU features
- if you have a great feature that needs to be integrated and can be done with ffmpeg - feel free to submit code
- besides that, you can also check the [TODO](https://github.com/ffplayout/ffplayout-engine/projects/1) to see if more is planned

JSON Playlist Example
-----

```json
{
    "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:

```json
...
        {
            "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!
