ffplayout_engine

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-frontend: web-based GUI for ffplayout

Features

• have all values in a separate config file
• dynamic playlist
• replace missing playlist or clip with a dummy clip
• playing clips from watched folder
• send emails with error message
• overlay a logo
• overlay text, controllable through messenger or ffplayout-frontend (needs ffmpeg with libzmq)
• EBU R128 loudness normalization (single pass) (experimental)
• loop clip in playlist which out value is higher then its duration, see also Loop Clip
• loop playlist infinitely
• trim and fade the last clip, to get full 24 hours
• when playlist is not 24 hours long, loop filler clip until time is full
• set custom day start, so you can have playlist for example: from 6am to 6am, instate of 0am to 12pm
• normal system requirements and no special tools
• no GPU power is needed
• stream to server or play on desktop
• on posix systems ffplayout can reload config with SIGHUP
• logging to files, or colored output to console
• add filters to input, if is necessary to match output stream:
  • yadif (deinterlacing)
  • pad (letterbox or pillarbox to fit aspect)
  • fps (change fps)
  • scale (fit target resolution)
  • aevalsrc (if video have no audio)
  • apad (add silence if audio duration is to short)
  • tpad (add black frames if video duration is to short)
• add custom filters
• add custom arguments
• different types of output:
  • stream
  • desktop
  • HLS
  • custom
• Multi Channel

Requirements

• python version 3.6+
• python module watchdog (only when playlist_mode: False)
• python module colorama if you are on windows
• python modules PyYAML, requests, supervisor
• ffmpeg v4.2+ and ffprobe (ffplay if you want to play on desktop)
• if you want to overlay text, ffmpeg needs to have libzmq
• RAM and CPU depends on video resolution, minimum 4 threads and 3GB RAM for 720p are recommend

JSON Playlist Example

{
    "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

The playlist can be extend, to use custom attributes in your 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:

...
        {
            "in": 0,
            "out": 149,
            "duration": 149,
            "source": "https://example.org/big_buck_bunny.webm"
        }

But be careful with it, better test it multiple times!
