IMX Scaler / CSC m2m driver.

Another datapoint:

This pipeline generates good 1080p output:
-------------------------------------

gst-launch-1.0 filesrc location= Downloads/big_buck_bunny_1080p_h264.mov ! qtdemux ! h264parse ! v4l2video3videodec capture-io-mode=dmabuf ! videoconvert ! ximagesink sync=false



This one generates 1080p frames, but they appear to be doubled-up - ie. the vertical resolution is 540ish, but the frame is still 1080 high.

horizontal resolution looks unaffected.
