[FFmpeg-user] how to turn off loop?

[Spencer Graves]

Hello:


       How can I stop an ffmpeg output file from looping?


       With help from this list, I produced a 1-second video from the 
attached mp2 and png files using "ffmpeg -y -r 1 -i tst.mp2 -r 2 -i 
tst%d.png -b 300k tst.mp4".  Unfortunately, the output restarts each 
time after it finishes.  "http://ffmpeg.org/ffmpeg.html" suggests that 
"-loop_output 1" should tell it to loop the output only once. However, 
when I try that, I get "Unrecognized option 'loop_output'. Error 
splitting the argument list: Option not found".  See below.


       Suggestions?


       Thanks,
       Spencer
