Error number -22 occurred ( -f bestvideo+bestaudio )

[ericzutter]

Highest resolution for video in example is "-f 18". Instead of downloading highest resolution, youtube-dl.exe with parameter "-f bestvideo+bestaudio" downloads a lower resolution and gives an error. How download highest resolution from all DASH formats and all NON DASH formats ?

C:>youtube-dl.exe -v -f bestvideo+bestaudio https://www.youtube.com/watch?v=25gWNvrRDPU

By specifying bestvideo+bestaudio, it grabs the best of each without the other and merges the two. The error you're getting is because the webm format can't have aac audio in it. This is documented in #3610.

Theoretically, if you just want to download the best quality, for this video only, then you could do:
youtube-dl -f 18+141 https://www.youtube.com/watch?v=25gWNvrRDPU

However, upon inspection this video is actually 352x240. That's the format 18.

There's a new option available, which is relevant for you, in one of the newest versions of youtube-dl. You can use -f "bestvideo[ext=mp4]+bestaudio" to download the best mp4 video available.

Thanks @clb92. That is a great feature and unfortunately it is not documented on the manpage or help.

[dstftw]

@Tatsh really?

[Tatsh]

@dstftw That link does not mention that one of the conditions is [ext=...]. Not all the conditions are documented. And youtube-dl -h | fgrep ext= outputs nothing. Now maybe you would not expect that in the --help text but I would certainly expect the format selection to be much more straightforward about valid syntax rather than giving some ideas via paragraphs. By comparison the Output Template section gives much more clear information by listing all possible values.

[dstftw]

@Tatsh it actually does

and for ext, acodec, vcodec, container, and protocol and the comparisons =, !=

It's not feasible to write an example for every combination of field and comparison.

It looks like this issue is resolved, and may be closed.
