           Summary: "[swscaler @ 0000000000288E00] full chroma
                    interpolation for destination format ' yuv444p' not
                    yet implemented"
           Product: Libav
           Version: git HEAD
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: Normal
         Component: general
        AssignedTo: libav-bugs at libav.org
        ReportedBy: lexlexlex at gmail.com


The titular error message is displayed in the circumstances portrayed in the
following image:  http://lex.clansfx.co.uk/dump/0000009A.png

The expected output is to not print the error message.  I was told to report
this here by BBB from #x264dev on freenode.  He said he'll check it out soon.
