option renamed for consitancy with ffmpeg (ver -> er)
 bug numbers changed (1234->1248) as some files need multiple ones

lavdopts: (decoder options)
---------------------------
ver error resilience
-1 needed for some very broken, encoders which completly ignore the
standards (one M4S2 asf sample know to need this) (default)
0
1 more aggressive error detection, lavc might think that some correct
streams contain errors
ec error concealment
1 use strong deblock filter for damaged MBs
2 iterative MV search (slow)
3 all (default)
Note: just add the ones u want to enable
bug manual workaround encoder bugs (cant be easily detected automatically)
0 (default)
1 for msmpeg4v3 workaround for some old lavc generated msmpeg4v3 files
1 for mpeg4 workaround some opendivx? files (autodetected hopefully)
see http://heroinewarrior.com for some samples
2 for mpeg4 workaround xvid interlacing bug
3 for mpeg4 workaround for UMP4 (autodetected hopefully)
er error resilience
0 disabled
1 carefull (should work with broken encoders)
2 normal (default) (works with compliant encoders)
3 agressive (more checks but might cause problems even for valid bitstreams)
4 very agressive
bug manual workaround encoder bugs (autodetection isnt foolproof for these)
0 nothing
1 autodetect bugs (default)
2 for msmpeg4v3 some old lavc generated msmpeg4v3 files (no autodetect)
4 for mpeg4 xvid interlacing bug (autodetected if fourcc==XVIX)
8 for mpeg4 UMP4 (autodetected if fourcc==UMP4)
16for mpeg4 padding bug
32for mpeg4 illegal vlc bug (autodetected per fourcc)
Note: just add the ones u want to enable
gray grayscale only decoding (a bit faster than with color ...)
