These are the consequences of not extracted DASH manifest. Only vevo videos are affected.

[Klaus1189]

OK, why is the dash manifest not extracted? To be honest I don't even know what this means.
I just recognized youtube-dl is "extracting MPD manifest". Is this correct? And again I don't know what youtube-dl is doing there.

[Klaus1189]

Is there a way to download the dash webm videos of vevo youtube videos?

[dstftw]

As usual with 9c7b389.

[Klaus1189]

Sorry, but what do I have to do?

[dstftw]

Run youtube-dl from sources or wait for a new release.

[Klaus1189]

Ahh OK, I got it. Thanks

[heartbeep]

@dstftw are you suggesting this issue is fixed in the latest source? That doesn't seem to be the case.

[dstftw]

It's not fixed it's worked around. These formats served not only within MPD manifest.

[Klaus1189]

What is the difference between fixed and worked around?
The dash webm are in the source available as you already mentioned, right?

[heartbeep]

@dstftw (and anyone else) any suggestions for someone trying to solve this issue? (I want the actual MPD manifest, not a workaround to get the formats it contains.) I’m willing to take a stab at this if I can get some direction. Thank you.

[dstftw]

I personally don't see much point investing time in this since it won't bring any crucial benefit.

[heartbeep]

@dstftw I know it may not bring a significant benefit to the typical youtube-dl user, but from my perspective it is crucial and it would be worth investing the time if I knew what to do.

[Hrxn]

@0xABC Could you give an example, maybe? What is different with the MPD manifest?
I'd just like to understand a possible use case..

[heartbeep]

@Hrxn I am actually using the MPD manifest in a video player to play the video with the DASH feature.

All videos mentioned here have the same problem as examples in #5118. Briefly, there's currenly no known way to download DASH MPD manifests found in get_video_info pages declared with use_cipher_signature=True. If you know how, please propose it.
