How did your download manage to cut it in half? BTW, you can feed the
stream URL directly to ffplay (your URL may vary):
$ ffplay -i 'https://r6---sn-5hnedn7s.googlevideo.com/videoplayback?mime=video%2Fmp4&dur=9590.119&upn=jYWGghj_TK4&itag=22&ip=80.144.60.117&ratebypass=yes&mn=sn-5hnedn7s&mm=31&source=youtube&expire=1461538813&pl=14&mv=m&mt=1461517049&ms=au&id=o-AImla_PoEMqA6TrhRrLn4QozlmIZAZYKbo8o_jfqycn9&initcwndbps=247500&key=yt6&sparams=dur%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cnh%2Cpl%2Cratebypass%2Crequiressl%2Csource%2Cupn%2Cexpire&lmt=1460246095785485&requiressl=yes&ipbits=0&nh=IgpwcjAxLmFtczE2KgkxMjcuMC4wLjE&fexp=9405960%2C9416126%2C9416891%2C9420095%2C9421503%2C9422596%2C9424134%2C9426926%2C9428398%2C9431012%2C9431708%2C9431814%2C9432367%2C9432683%2C9432751%2C9433096%2C9433180%2C9433947%2C9434126%2C9434204&signature=0559118CDA43302FF412EB7DA728B559D0265AE1.B86A5764633D44AE3165B71ECAFE036563DA7786&sver=3' -vf "crop=w=iw/2:h=ih:x=0:y=0,scale=w=2*iw:h=ih,setdar=2*dar"

Mine has. Perhaps your download tool downloaded the video-only stream.
(Have you checked "youtube-dl -F"?)

Not here. YouTube recognizes it as 3D and does some magic when playing
(in Firefox). (Note, I think I am using YouTube without Flash. Not that
it should matter.)

What are those Linux YouTube players? smtube possibly?

You're still not correctly writing what you're trying to achieve and
what you're actually doing. Like really doing.
