Comment (by littlebat):

 I applied the patch provided in: http://ffmpeg.org/pipermail/ffmpeg-
 devel/2013-March/141153.html , and burned 3 subtitles(French, Simplified
 Chinese, Traditional Chinese) into video for whole input file which about
 1 hour duration separately. I played them concurrently and confirmed all
 these 3 subtitles have been burned into video exactly.

 So, this bug seems has been fixed.

 Thanks for your good job:-)

 Here is one of my command line to burn subtitle into video:

 mdx at debian:~/test$ /opt/ffmpeggit/bin/ffmpeg -i CD1.mkv -filter_complex
 '[0:v][0:s:1]overlay[v]' -map [v] -map 0:a -c:v mpeg4 -q:v 2 -c:a copy
 CD1_s_1.mkv
