           Summary: x264enc caps negotiation broken, tries input 4:4:4 for
                    non-4:4:4 profiles
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: blocker
          Priority: Normal
         Component: gst-plugins-ugly
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: olivier.crete at ocrete.ca

     GNOME version: ---


The x264enc getcaps function should probably filter out 4:4:4 YUV formats if
the downstream caps don't support a 4:4:4 profile.

gst-launch-1.0 -v  videotestsrc ! video/x-raw, format=BGRA ! videoconvert ! 
x264enc ! video/x-h264, profile=main ! fakesink

This is a regression from 1.0, probably introduced when 4:4:4 support was
added.
