DR1 IP/IPB supoprt (I/P only with -double) -- OSD *must be* disabled! :)
note: playing IPB mpeg (-vc ffmpeg12) looks broken due to bad frame display order (differs from frame decoding order) - requires workaround or PUT_IMAGE implementation... git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@6759 b3059339-0415-0410-9bf9-f77b7e298cf2
