  GStreamer | gst-ffmpeg | Ver: HEAD CVS
           Summary: ffenc_huffyuv fails to encode large resolutions
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: fredrik.p.persson at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Try this:

gst-launch videotestsrc num-buffers=500 ! capsfilter
caps="video/x-raw-rgb,width=1000,height=800" ! videorate ! ffmpegcolorspace !
timeoverlay ! ffmpegcolorspace ! ffenc_huffyuv ! avimux ! filesink
location="test.avi"

You will get this:

....

The resulting file (test.avi) will be corrupt. (At least no media player I've
tried can play it back.)

Lower resultions, for example 640x480, is OK. 

Since the only available lossless video encoders are ffenc_ffv1, ffenc_huffyuv
and ffenc_ffvhuff where ffenc_ffv1 and ffenc_ffvhuff seems totally broken,
gstreamer effectively has NO lossless encoder for HDTV resolutions.
