The simplest case is requesting a specific format, for example with `-f 22` you can download the format with format code equal to 22. You can get the list of available format codes for particular video using `--list-formats` or `-F`. Note that these format codes are extractor specific.

This would make it more future-proof in case some of the sources became unavailable. When extracting metadata try to provide several scenarios for that.
