<DIV><FONT face="MS UI Gothic" size=2></FONT> </DIV>
<DIV><FONT face="MS UI Gothic" size=2> Then, I want to change
the 'videotestsrc' to 'filesrc', and set the 'location' of 'filesrc' as a
'*.mp4'.</FONT></DIV>
<DIV><FONT face="MS UI Gothic" size=2></FONT> </DIV>
<DIV><FONT face="MS UI Gothic" size=2> The command looks like
