This command does not involve hardware decoding through VA-API. So, as Haihao
mentioned further on, you are hitting and Xv issue.

The correct command to enable VA-API decoding is mplayer -vo vaapi -va vaapi

... but, it won't succeed on Ivybridge. Ivybridge can support 4K video but only
if a single dimension is 4K. i.e. 4K x 3K or 3K x 3K would work, but not 4K x
4K.
