[x86_64] 2.6.14-git13 mplayer fails with "v4l2: ioctl queue buffer failed: Bad address" (2 Nov 2005, 11 Nov 2005)

[Junichi Uekawa <dancer@netfort.gr.jp>]

Hi,

I've tried running mplayer v4l2 input on a bt878 card, and it fails.
xawtv works fine, and 2.6.14-rc5 used to work fine.

On git 3b44f137b9a846c5452d9e6e1271b79b1dbcc942 :

$ mplayer  tv://1 -tv driver=v4l2
