why does this change?

We need to send a VideoFrame that contains one mailbox with one native texture
where the format of the VideoFrame is UYUV.

[reveman, 2015/08/22 14:04:46]

don't we sample out of this texture as if it was ARGB and the driver does the
color space conversion? just like other native textures produced by hardware
decode..
