[arch-general] Hardware video acceleration

[Ralf Mardorf]

Hi,

when playing youtube videos hardware video acceleration seems to gain
absolutely nothing on my machine or I've done something wrong ;).

Am I missing something?

The percent values playing a youtube video with and without enhanced-
h264ify are raw estimated values, based upon my impression, so I
consider those values as quasi equal, the minimal difference is
neglectable.
