forked from mia/Aegisub
2b2a7f4212
Currently lacks a few features (no RFF flag parsing is done, interlacing is not supported and the colorspace conversion to RGB32 could stand considerable improvement) but at least now Aegisub is capable of reading video without FFMS2 or Avisynth. Updates #920. Originally committed to SVN as r3168.
