-ERANGE could be returned by drm_plane_helper_check_state if kmssink
requests scaling, which we don't support in the imx-drm driver.
Though I'm not sure why that whould happen on 1.12, especially if the
video size matches the output size.

What gets logged with GST_DEBUG="kmssink:6" set in the environment?

What gets logged if you enable KMS debug flag (echo 4 >
/sys/module/drm/parameters/debug)?
