Unexpected results when downloading youtube clips in post-live manifestless mode about yt-dlp HOT 3 OPEN

When a livestream has just ended and is in "post-live manifestless mode", yt-dlp generates its own playlist(s) of fragments for the different formats' video/audio stream(s). This pseudo-manifests cannot be passed to ffmpeg, which is used for clip downloads (since ffmpeg can seek and download sections), so yt-dlp instead passes the actual DASH manifest URL to ffmpeg. At that point, what is downloaded depends on ffmpeg's default behavior for processing the DASH manifest, and that's likely not going to be what yt-dlp intended. In your verbose log's case, ffmpeg grabs the last variant of the DASH manifest, which happens to be one of the audio tracks.

The good news is that this video will be processed by youtube and no longer be in "post-live manifestless mode" if you try again after some hours have passed

Thanks for this!

I was able to confirm that it's able to download the correct format for livestream VODs from last week; it definitely is a "stream just ended" thing.
