Looping an mp4 video file -> a HLS stream

[Oliver-Mardle]

I have a single video file source that I'm outputting to a HLS file.

Is there a quick / easy way to loop this file so I get a continuous stream? The stream is processed by FFMPEG, I couldn't see any obvious "fflags".

Hi @Oliver-Mardle.

By default your video file will be continuously looping.

videostream = mksafe(single("video.mp4"))

midfi = %ffmpeg(format="mpegts",  
  %audio(
    codec="aac",
    samplerate=44100,
    channels=2,
    b="192k",
    profile="aac_low"
  ),
  %video(codec="libx264",
    g="50",maxrate="6500k",
    bufsize="13000k",
    preset="ultrafast",  
    tune="zerolatency"
  )
)
 
streams = [("midfi", midfi)]

def segment_name(~position,~extname,stream_name) =
  timestamp = int_of_float(time())
  duration = 3
  "#{stream_name}_#{duration}_#{timestamp}_#{position}.#{extname}"
end

output.file.hls(playlist="stream.m3u8",
                segment_duration=3.0,
                segments=10,
                segments_overhead=10,
                segment_name=segment_name,
                "/hls",
                streams,
                videostream)
