• plyr fixes
• plyr controls becomes tiny if you select 144p
• quality 144(integrated) (in reality id 17) shows no video -- only audio
• Warning: unrecognized codec: mp4v.20.3
• network inspector shows blocked csp (av-merge) -- dash fails to play, only integrated may work -- Refused to connect to 'https://rr5---sn-8p85jvh-nv4s.googlevideo.com/videoplayback/name' because it violates the following Content Security Policy directive: "default-src 'self' 'unsafe-inline'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback. -- huh did another install on ubuntu2004 and it works
• if theater mode is on the video resizes to 100% of the quality (it can be tiny) -- if intended please make it optional
• if quality pop up bubble has too much in it add scroll bar (overflow?)
• video is shoved in the header -- add margin header{margin-bottom:1em;}.video-info{margin-top:1em;}
• make theater like old youtube -- fixed size video with black background image
• for reference when yt was good
