Hi,

Changed the input format:
Video -> yuv420p
Sub -> yuv*a*420p (to include Alpha Channel)

Now the video is showing, but still no subtitles.
Still get the error message:
*Error while add the frame to buffer source(Internal bug, should not have
happened).*


./ffmpeg -threads 1 -loglevel info -nostdin -y -fflags +genpts-fastseek \
   -ss 00:00:00 -t 00:00:15 \
