Fredrik Mellbin 38c420c7bd FFMS2:
Renamed a public api function just because I can
Less access violations (AGAIN!)
Dumping now implies indexing too
Much better logic for automatically indexing files when FFAudioSource is used in avisynth
Changed defaults for FFIndex
Now FFmpeg's internal codec lists are used for lookup from the non-lavf based parts

Originally committed to SVN as r2991.
