DASH manifest Post-Live-DVR streams - Error 500, `TypeError: Invalid URL`

[cadusilva]

This morning I wasn't able to watch videos anymore. The poToken is generated, but the video doesn't play. Looking at the companion logs, there's this error:

    },
    videoplayback: { ump: false, video_fetch_chunk_size_mb: 5 }
  },

This also seems to have broken yewtu.be and inv.nadeko.net.

Maybe this was a temporary outage, the videos are playing again.

Keeping this open for investigation.

Long story short you need to modify the Invidious watch page code to use YouTube's provided HLS manifest for Post-Live-DVR streams, like you are already doing for live streams. These lines would need to be modified: https://github.com/iv-org/invidious/blob/master/src/invidious/views/components/player.ecr#L7-L9

Post-Live-DVR streams are live streams that have ended but have not been converted to VODs by YouTube yet, so the DASH versions include self-initialising segments just like the live streams do, which are incompatible with video.js. The reason why it feels temporary is because streams that are in Post-Live-DVR status get converted to VODs eventually (how long it takes varies, presumably it depends on metrics such as how popular the video is and how much capacity the video processing servers have at a given moment).

As for the error itself, that is happening in YouTube.js Post-Live-DVR DASH manifest generation because it has to make requests to fetch a media segment to get the information needed to generate the manifest, but because Invidious companion transforms the URL into a string that starts with a path instead of an entire URL deno errors when it tries to fetch data with it. While yes YouTube does provide a DASH manifest and HLS manifest for live streams and post live DVR, they only go back 4 hours and 30 minutes respectively so YouTube.js supports generating a Post-Live-DVR manifest that includes everything, but as already mentioned above because you are using video.js the only thing you can use is the HLS manifest provided by YouTube.
