Checklist

• I'm reporting a broken site support issue, I've noticed certain videos not allowing me to download and giving me errors, not every video does this but a few like this one here will

https://www.youtube.com/watch?v=X51Za9YcAYY

I've also tried it via Invidious with the same outcome.

• I've verified that I'm running youtube-dl version **2020.06.16.1, I've run the various methods to update it several times and can confirm it is the latest version.

• I've checked that all provided URLs are alive and playable in a browser, No age restrictions, no weird exceptions, they work on all the sites I've tried, so regular youtube and Invidious.

• I've checked that all URLs and arguments with special characters are properly quoted or escaped, no playlists or weird quality characters blocking it, I've tested other videos and those work fine but others do not.

• I've searched the bugtracker for similar bug reports including closed ones, I've searched down to the exact error code and saw nothing really similar. This doesn't appear to match the pinned reports at the top.

• [x ] I've read bugs section in FAQ, read through the procedures multiple times to make sure I'm getting it right.

## Description

When I try to download certain videos, such as the one above and a few others from the same channel, they give me errors, other videos download fine and even playlists from the listed channel appear to download just fine, I've tried different formats and combinations of commands and nothing changes. My normal default arguments include

"--add-metadata --all-subs --embed-subs --rm-cache-dir"

But excluding all of those still results in the errors I have above
