Description

Hello,

I understood on other posts that this error was related to youtube.

However, I can't download the video in another format. Indeed, for this video https://www.youtube.com/watch?v=sCwOUOcVZhs format 22 displays this error, but format 18 works. In the order, it is filled in 22/18, obviously it does not try to download in the second format.

How to make sure that it makes an attempt with the second format rather than returning the error? Thank you

[dstftw]

You can't do that.

[triplesixman]

You can't do that.

Hey, the script can't be modified to detect this error and try the format 18 ?

[Watilin]

I support this request. The “no data blocks” issue gets rather frequent on Youtube at times, and it would be nice to have youtube-dl automatically switch to an alternate format whenever it’s needed.

[ventilaar]

You can't do that.

But you should be able to. Why else would the manual mention this?

If you want to download multiple videos and they don't have the same formats available, you can specify the order of preference using slashes.
