youtube_dl.utils.ExtractorError: requested format not available

Description

Errors trying to download any videos from twitch. Requested format not available. My guess is they changed the API.

If criticalrole is down, the issue is reproducible with any video on twitch..
Eg. : https://www.twitch.tv/videos/549337847

There are no formats satisfying bestvideo+bestaudio as clearly stated in the error message.

[marchom]

It might be helpful to return the requested format as part of the error message, so that it's clear it comes from the user and not from the site. Up to this bestvideo+bestaudio has always been available on twitch.tv. That confused me.

Thanks and sorry for the noise.

[dstftw]

FYI, bestvideo was never available on twitch.
