ffmpeg failure

[f1vefour]

I'm getting this error after a download completes.

download complete.

starting ffmpeg conversion of HLS stream to mp4 file..
ffmpeg error:

ffmpeg (v4.4.2) is in my path and working

[warren-bank]

yeah.. these comments in an older issue explain the problem:

1. byte ranges, rather than video segments
2. ffmpeg workaround
3. v1.5.4

in short, strictly speaking, tubitv isn't hosting HLS video any longer.. and ffmpeg doesn't like it when HLS manifests only contain a single media segment

[warren-bank]

quick test:

  tubidl --version

  # 1.5.4

• series: Mr. Bean The Animated Series
  • each episode is 12 minutes
• episode: S01E01 - In the Wild

  set tmpdir="e:\.workspace"
  mkdir %tmpdir%
  cd /D %tmpdir%

  tubidl -q -mc 5 -u "https://tubitv.com/tv-shows/381933/s01-e01-in-the-wild"

  # starting download of 1 video data files..
  # done
  # 
  # starting download of 1 audio data files..
  # done
  # 
  # download complete.
  # 
  # starting ffmpeg conversion of HLS stream to mp4 file..
  # ffmpeg error:
  # starting fallback ffmpeg conversion to mp4 file..
  # done

  ffplay "Mr. Bean The Animated Series/S01E01 - In the Wild/mp4/video.mp4"

conclusions:

• the ffmpeg workaround added in v1.5.4 still seems to work

[warren-bank]

actually.. taking a closer look at your error message.. it seems that:

• you are attempting to run the ffmpeg workaround: run_fallback_ffmpeg_video_conversion
• and it's throwing an error because one of the two files that it assumes to exist do not

question:

• what are the filenames of the video and audio files that did download (to their respective directories)?

[warren-bank]

the problem was that the fallback strategy assumed that the audio stream would be named stream_0, which is probably the case when the media only contains a single audio stream, but your example has 2: english and english - audio description

I just pushed v1.5.6.. which first tries to find the audio stream having one of the two names: stream_0 or english.. and if neither is found, it then walks the audio directory to find a suitable file.. and only exits with an error message when none can be found.

It's working now, ffmpeg falls back and joins the audio/video into mp4 correctly.

Thank you for the quick fix, closing the issue.
