Inconsistency in youtube vcodecs

[wiiaboo]

Trying to use [vcodec=vp9] to limit downloading to this codec fails to get formats which are marked with vcodec=VP9 (formats 278,302-315) and using [vcodec=VP9] fails at getting formats that aren't explicitely marked with vcodec=VP9 (formats 242-248,271-272).

Example:

Solution:
either making the vcodec selector be case-insensitive or change formats 278,302-315 to use vcodec=vp9

Thanks for the report, it will always set them in lowercase in the next version.
Note that if you are just interested in getting the webm files you can use bestvideo[ext=webm], which will also pick vp8 formats.

I was using that to fix behavior - since ffmpeg/mpv can't handle mp4 dash well but webm dash is okay - but I don't really want VP8. Would rather have messed up seeking with H.264 than using VP8.
