In RFC6381, there's no rule stating that the first part of codecs should
be video and the second part should be audio, while it seems the case
for data reported by YouTube.
Should make downloading with filters more precise and easier, ie. bestvideo[vcodec=h264]. By default a lot of codecs are specified as avc1.xxxxxx and unique for each format, which makes them unusable for bestvideo selection.

[extractor/common] Remove unused import
[nfb] PEP 8
Previously, when we encountered a 404 - such as youtube-dl https://www.youtube.com/ohJeiboh8oorehai - we crashed with a regexp error. Instead, make sure to go on and eventually report a 404.
60fps DASH formats do not appear in the DASH manifest, but the non-DASH
video info page does contain additional parameters for DASH formats that
we can parse.
Use those when they exist.
This fixes "bestvideo" not selecting 60fps formats over similar 30fps
formats just because the file size is unknown.
This is according to how youtube handles multiple v= values in one URL.
Before this, it was possible to make a single URL show up differently
on youtube itself, and if you downloaded/viewed it with youtube-dl/mpv
DASH manifest pointed by dashmpd from the video webpage and one pointed by get_video_info may
be different (namely different itag set) - some itags are missing from DASH manifest pointed by
webpage's dashmpd, some - from DASH manifest pointed by get_video_info's dashmpd).
The general idea is to take a union of itags of both DASH manifests (for example video with such
'manifest behavior' see https://github.com/rg3/youtube-dl/issues/6093).
