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.
