[vlc] YV12 rendering errors

[MagicITX]

I was having trouble with VLC on a VIA EPIA system using the openchrome Xv
driver.  While working to resolve it with Thomas Hellstrom of the openchrome
project he reported: "It seems that VLC doesn't format the Xv images as the
X server tells it to do. In particular, it doesn't adhere to pitches. This
makes YV12 produce rendering errors on widths that are not multiples of 32,
but YUY2 is OK for widths that are multiples of 16. (when dmablit is on,
otherwise the openchrome driver requests that strides and widths are the
same). This should really be communicated to the VLC developers."
