"YouTube is forcing SABR streaming for this client" ?

[holta]

1. @deldesir @chapmanjacobd a fresh install of IIAB Calibre-Web and then "Download to IIAB" worked with https://youtu.be/8dAXkIyyXek — but then failed as follows with subsequent attempts to download YouTube videos or playlists:

2. Is "YouTube is forcing SABR streaming for this client" the core of the issue?

3. Are there any manual workarounds that can/should be attempted?

ASIDE: Just FYI this happens to be running on PR iiab/iiab#4122 on Android 14.

Yeah that's pretty much expected to happen these past couple months when you don't have deno installed.

Personally I'm having downloads fail the past couple days even with everything correctly installed and on the nightly branch of yt-dlp. I get the feeling that it will be better in a few days from now but you'll still want to get deno when downloading more than a few videos.
