Your suggestion works, thank you. After applying your IPU patch and
using this Gstreamer pipeline:

gst-launch-1.0 filesrc location=/media/clip.mp4 ! qtdemux ! h264parse
! v4l2h264dec ! video/x-raw,format=NV12  !  kmssink

The video is played with correct colors.

Can we make the NV12 format be used automatically so that a simple
'gst-play-1.0 /media/clip.mp4' works?

With this Gstreamer patch, I don't see the segfault anymore, but it
plays in black-and-white.

Thanks
