Long Form Videos Fail to Transcode

[MattyBoombalatty]

Describe the current behavior

Long-form videos with transcription enabled will fail to publish after transcoding. I have the 480p and original resolution transcoded. In the admin panel, all the resolutions are there plus the audio only file, but it stays on "waiting for transcode".

Please note that even after disabling transcription and re-running the transcoding job, the result is the same (transcoding fails). An example can be found here

When the transcoding job is forced, this is the error:

  "videoUUID": "8554f991-4152-48cd-97ff-e3aaf38bd9fb",

Thanks! The root cause of the issue if the video doesn't have a thumbnail/preview which is very weird. Do you know how you uploaded this video?

[MattyBoombalatty]

This was a live stream from another user. I wonder... Let me see what happens if I upload a thumbnail and then redo the transcoding. I have custom video thumbnails so it's entirely possible I didn't replace the default ones correctly.

[MattyBoombalatty]

Okay, manually uploading a thumbnail and then re-transcoding fixed the issue. I wonder why it's not automatically generating thumbnails for all videos...

[MattyBoombalatty]

I reset the video thumbnail generation sizes back to normal (I had doubled them) so we'll see if that works.

thumbnails:

  # When automatically generating a thumbnail from the video

  generation_from_video:

    # How many frames to analyze at the middle of the video to select the most appropriate one

    # Increasing this value will increase CPU and memory usage when generating the thumbnail, especially for high video resolution

    # Minimum value is 2

    frames_to_analyze: 20
  # Only two sizes are currently supported for now (not less, not more)
  # 1 size for the thumbnail (displayed in video miniatures)
  # 1 size for the preview (displayed in the video player)
  sizes:
    -
      width: 280 # 280
      height: 157 # 157

    -
      width: 850 # 850
      height: 480 # 480
