Right now , on https://dev.twitter.com/cards/types/player for the
twitter:player:stream attribute it says the video must be
H.264, Baseline Profile (BP), Level 3.0, up to 640 x 480 at 30 fps.
this means we can’t send 720p or 1080p but only 640x480 ? seems to be a quite low resolution to set as a max…
can we send a big resolution video url in the twitter:player:stream attribute, or not ? (or maybe multiple sources ?)
