Description

Tried downloading this video and it comes out corrupted: neither VLC nor QuickTime can play it on OS X 10.13.6. Specifically, the video plays for the first 10 seconds and then the screen goes black with some noisy pixels on the top. (There is no sound in the first 10 seconds in the original video here.)

This is the 3rd time I attempted to download it.

The relevant warning line in the log is:

WARNING: [youtube] Ct9VTQnPa5c: Skipping DASH manifest: ExtractorError("Failed to download MPD manifest: HTTP Error 404: Not Found (caused by <HTTPError 404: 'Not Found'>); please report this issue on https://yt-dl.org/bug .

Most likely DRM protected.

Thank you! Too bad.

Is there a way for me to confirm it's DRM protected?

Also, are there any resources on how this type of DRM works?
