Multi SRT input fails

[LifelessMuffin]

Describe the bug Hi toots, there are still some issues with the multi SRT to HLS script from some weeks ago (reference to #3485 ) it basically crashes.

To Reproduce Script:

input_a = input.srt(port=9000, mode="listener")
input_b = input.srt(clock_safe=false, port=9001, mode="listener")
input_c = input.srt(clock_safe=false, port=9002, mode="listener")

let {video = video_a, audio = audio_a} = source.tracks(input_a)
let {video = video_b, audio = audio_b} = source.tracks(input_b)
let {video = video_c, audio = audio_c} = source.tracks(input_c)

muxed_input =
  source(
    {
      audio_a=audio_a,
      audio_b=audio_b,
      audio_c=audio_c,
      video_a=video_a,
      video_b=video_b,
      video_c=video_c
    }
  )

streams =
  [
    (
      "transmux_high",
      %ffmpeg(
        format = "mpegts",
        %audio_a.copy,
        %audio_b.drop,
        %audio_c.drop,
        %video_a.copy,
        %video_b.drop,
        %video_c.drop
      )
    ),
    (
      "transmux_medium",
      %ffmpeg(
        format = "mpegts",
        %audio_a.drop,
        %audio_b.copy,
        %audio_c.drop,
        %video_a.drop,
        %video_b.copy,
        %video_c.drop
      )
    ),
    (
      "transmux_low",
      %ffmpeg(
        format = "mpegts",
        %audio_a.drop,
        %audio_b.drop,
        %audio_c.copy,
        %video_a.drop,
        %video_b.drop,
        %video_c.copy
      )
    )
  ]

def segment_name(~position, ~extname, stream_name) =
  timestamp = int_of_float(time())
  duration = 2
  "#{stream_name}_#{duration}_#{timestamp}_#{position}.#{extname}"
end

output.file.hls(
  fallible=true,
  segment_duration=2.0,
  segments=5,
  segments_overhead=5,
  segment_name=segment_name,
  "/tmp/hls",
  streams,
  muxed_input
)

Output:
