-------------------------------------------+--------------------------
 When using '-vcodec ffv1 outfile.mkv', I use mkvalidator to check the
 resulting file which lists warnings for every cluster.

 Making a ffv1 in mkv: http://pastebin.com/dhAHLpvc

 Warnings from mkvalidator that first frame is cluster is not keyframe:
 http://pastebin.com/TJHtaAvY (aren't all ffv1 frames keyframes)

 Same file in mkvtree: http://pastebin.com/cZ3bjF7M
