Things seem to visually "stick" briefly at scene transitions in VP9 playback on slower devices (iPod Touch 5th gen, iPhone 5c, tested with 'Curiosity' at 360p or 480p respectively). I think this is because the keyframes are more time-intensive in VP9, with both heavy intraframe compression and perhaps a hidden alt-ref frame next to it.
ogv.js solves this by buffering a few decoded frames ahead, smoothing out the final playback. Requires copying data out of the internal buffers. Should be easy to adapt.
