Description
It's a matter of setting the VADisplayAttribRotation attribute to VA_ROTATION_{NONE,90,180,270}. But I couldn't figure out where exactly to set the attribute and how to handle the width and height swapping required for 90/270 rotation.

Research direction
Start by locating mpv's VA-API display setup and the code that handles video dimensions; the issue names no files or tests. Trace where VADisplayAttribRotation can be configured and how VA_ROTATION_NONE, 90, 180, and 270 affect width and height, then verify rotated playback.
