            Bug ID: 772584
           Summary: x265 fails when trying to encode Y444
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: florent.thiery at ubicast.eu
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

gst-launch-1.0 videotestsrc ! "video/x-raw, format=(string)Y444" ! x265enc !
fakesink -v

gstx265enc.c(785): gst_x265_enc_set_level_tier_and_profile ():
/GstPipeline:pipeline0/GstX265Enc:x265enc0:
Failed to find correct level, tier or profile in VPS

I saw this by trying to encode UYVY with an intermediate videoconvert; i am
guessing that videoconvert prefers Y444 ti I420 to preserve data, but x265
apparently doesn't work with Y444

gst-launch-1.0 videotestsrc ! "video/x-raw, format=(string)UYVY" ! queue
name=encoder ! videoconvert ! queue ! x265enc ! fakesink -v
