Odysee MP4 enclosures for Youtube

[thefranke]

Suppose you have a Youtube video URL of the format https://www.youtube.com/watch?v=VIDEO_ID. Several channels mirror their content on Odysee/LBRY, a decentralized video platform with a blockchain indexing all available videos.

Odysee features and API where one can check if a video available on Youtube is also available on Odysee/LBRY with the following API endpoint:

https://api.odysee.com/yt/resolve?video_ids=VIDEO_ID

Here's an example from the 3Blue1Brown channel:
https://www.youtube-nocookie.com/watch?v=ldxFjLJ3rVY

This is the output from https://api.odysee.com/yt/resolve?video_ids=ldxFjLJ3rVY

{
  "success": true,
  "error": null,
  "data": {
    "videos": {
      "ldxFjLJ3rVY": "escher's-most-mathematically-interesting#08d66bfb0154b122ecdfbae78064c3c79d535274"
    },
    "channels": null
  }
}

The value of the video ID key ldxFjLJ3rVY is the claim ID on Odysee. This ID can be inserted into another URL of this format:

https://player.odycdn.com/api/v3/streams/free/' . str_replace('#', '/', $claimid) . '/video.mp4'

This effectively points to the CDN's cached MP4 of the same video on Youtube. This could be inserted into the Youtube bridge either as a <video> embed, an enclosure, or both.

Note this is only available for mirrored channels, but it would allow for subscriptions to just provide a plain video file that can be downloaded and watched later.

I have tested this already on my own project called RSS-Librarian. Any thoughts?
