* New command line switch for mplayer & mencoder:
-ifo <ifo file> Indicate the file that will be used to load palette and frame size for MPEG subtitles. * mencoder.c: Fix cropping when decoding MPEG2. * spudec.c: If scaling is needed only do it once. Change WITH_NO_ANTIALIASING to ANTIALIASING_ALGORITHM. * vobsub.c: Support reading info regarding size and palette from IDX file instead of IFO file. Support streams containing audio or video. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@5389 b3059339-0415-0410-9bf9-f77b7e298cf2
