目前rotate操作是调用opencl 旋转后送到竖屏drm显示的。

没看懂你的需求是啥，如果用的是官方默认的Linux的SDK，输入下面的命令看看；
echo "output:all:rotate90"> /tmp/.weston_drm.conf # All screens are rotated 90 degrees
先说正常情况：竖屏1080x1920的plane,播放视频，需要1080x1920分辨率的。一般视频是1920x1080格式，如果想在竖屏播放，必须rotate后成1080x1920的才可以发送给plane.
需求就是：想通过设置drm plane的rotate属性，比如设置旋转90度，之后向此plane发送1920x1080的视频，此plane是不是就可以“在内部rotate后”，显示到1080x1920的屏幕上？
