Can the ffmpeg command line in Linux be used to insert a subtitle text
file (sub.txt) into a video file av.mp4? If so, would you please give
an command line example?

I've tried following command and gotmerrors in CentOS 5.2:

$ ffmpeg -i tennis.mp4 -i subtitle.txt -vcodec copy -acodec copyan
-vcodec copy -scodec copy testsubtitle.mp4 -newsubtitle

built on Aug 26 2008 09:55:22, gcc: 4.1.2 20071124 (Red Hat 4.1.2-42)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'tennis.mp4':

Thank you.
