用mplayer外挂字幕一直不能成功。。。查了一下任务log，发现如下记录：
Setting process priority: high
getch2: 6 can't get number of input events [disabling console input]
Playing D:\Downloads\[POPGO][FREEWIND][Conan_Movie_9][DVDRIP][XVID_DD].avi.
AVI file format detected.
VIDEO: [XVID] 720x400 12bpp 23.976 fps 1397.1 kbps (170.5 kbyte/s)
Clip info:
SUB: Could not determine file format
Cannot load subtitles: D:\Downloads\[POPGO][FREEWIND][Conan_Movie_9][DVDRIP][XVID_DD].ass
难道是不支持ass格式？。。。
这个问题怎么解决呢？。。。
