 I have an ass file with some specific shapes, when I use command line
 <ffmpeg.exe -v 9 -loglevel 99  -i "D:\test\1.mp4" -vf "ass=D\\:test/1.ass"
 -f mp4 -y "D:\test\ffmpeg.mp4"> to burn it into video file, the shapes are
 in a mess. But when I use FFmpeg+AvisynthPlus (command line <ffmpeg.exe -i
 "D:\test\1.avs" -f mp4 -y "D:\test\ffmpeg+AvisynthPlus.mp4">) to burn it,
 the shapes are exact. All the files and logs are attached.
