Author: greg Date: Sat Mar 6 00:13:08 2010 New Revision: 30849 Log: Enable ASS/SSA subtitle support in mencoder
Enable ASS/SSA rendering through libass in mencoder. This duplicates a bit of code (to parse font attachments, for example). Additionally, add a filter "fixpts" that generates PTS, simulating fixed fps. PTS generated by this filter are then used for subtitle timing. Original patch by Nicolas George.
