sometimes it can happen, that a file is corrupt but still playable, this can produce an streaming error over all following files. The only way in this case is, to stop ffplayout and start it again here we only say it can stop, the starting process is in your hand best way is a systemd serivce on linux. stop_threshold: stop ffplayout, if it is async in time above this value.

    backup_count: 7
    log_path: "/var/log/ffplayout/"
    log_level: "DEBUG"
    ffmpeg_level: "ERROR"

processing:
    width: 1024
    height: 576
    aspect: 1.778
    fps: 25
    add_logo: True
    logo: "docs/logo.png"
    logo_scale: "100:-1"
    logo_opacity: 0.7
    logo_filter: "overlay=W-w-12:12"
    add_loudnorm: False
    loud_I: -18
    loud_TP: -1.5
    loud_LRA: 11
    output_count: 1

ffmpeg pre-compression settings, all clips get prepared in that way, so the input for the final compression is unique.

• aspect mus be a float number.
• with logo_scale = 100:-1 logo can be scaled
• with logo_opacity logo can make transparent
• with logo_filter = overlay=W-w-12:12 you can modify the logo position
• with use_loudnorm you can activate single pass EBU R128 loudness normalization
• loud_* can adjust the loudnorm filter
• output_count sets the outputs for the filtering, > 1 gives the option to use the same filters for multiple outputs. This outputs can be taken in 'ffmpeg_param', names will be vout2, vout3; aout2, aout2 etc.

INFO: output is progressive!

playlist:
    playlist_mode: True
    path: "/playlists"
    day_start: "5:59:25"
    length: "24:00:00"

Playlist settings - set playlist_mode to False if you want to play clips from the storage: section put only the root path here, for example: "/playlists". Subfolders is read by the script and needs this structur:

• "/playlists/2018/01" (/playlists/year/month)

day_start means at which time the playlist should start. Leave day_start blank when playlist should always start at the begin. length represent the target length from playlist, when is blank real length will not consider.

storage:
    path: "/mediaStorage"
    filler_clip: "/mediaStorage/filler/filler.mp4"
    extensions:
        - ".mp4"
        - ".mkv"
    shuffle: True

Play ordered or ramdomly files from path, filler_clip is for fill the end to reach 24 hours, it will loop when is necessary. extensions: search only files with this extension, add as many as you want. Set shuffle to True to pick files randomly.

---

text:
    add_text: True
    over_pre: False
    bind_address: "tcp://127.0.0.1:5555"
    fontfile: "/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf"
    text_from_filename: False
    style: "x=(w-tw)/2:y=(h-line_h)*0.9:fontsize=24:fontcolor=#ffffff:box=1:boxcolor=#000000:boxborderw=4"
    regex: "^(.*)_"

Overlay text in combination with messenger or the web frontend. On windows fontfile path need to be like this: C:/WINDOWS/fonts/DejaVuSans.ttf. In a standard environment the filter drawtext node is: Parsed_drawtext_2. over_pre if True text will be overlay in pre processing. Continue same text over multiple files is in that mode not possible. text_from_filename activate the extraction from text of a filename. With style you can define the drawtext parameters like position, color, etc. Post Text over API will override this. With regex you can format file names, to get a title from it.
