Hi,
I'm wondering why you set the media_profiles.xml to be media_profiles_720p.xml for the 6QP variant of the SabreSD whereas the 6Q version uses the default 1080p version?
See device/fsl/sabresd_6dq/init.i.MX6QP.rc file in any Marshmallow release:
# set media_profile.xml
setprop media.settings.xml /etc/media_profiles_720p.xml
Even the SabreAuto 6QP variant uses the 1080p, is it a mistake?
Regards,
Gary
