>>> best = video.getbest()
>>> best.resolution, best.extension
('480x854', 'webm')
get best resolution for a particular file format: (mp4, webm, flv or 3gp):
>>> best = video.getbest(preftype="mp4")
>>> best.resolution, best.extension
('360x640', 'mp4')
get best resolution for a particular file format, or return different format if it has the best resolution:
>>> best = video.getbest(preftype="mp4", ftypestrict=False)
>>> best.resolution, best.extension
('480x854', 'webm')
get url, for download or streaming in mplayer / vlc etc:

Download video, use specific filepath:
>>> myfilename = "/tmp/" + best.title + "." + best.extension >>> best.download(filepath=myfilename)
Get audio-only streams (m4a and/or ogg vorbis) (use video.videostreams to get video-only streams):
>>> audiostreams = video.audiostreams
>>> for a in audiostreams:
>>> print(a.quality, a.extension, a.get_filesize())
