[MPlayer-users] combining a still with an audio file

[Miriam English]

Find the length of the audio file in seconds and use that instead of the 
"443" below.
Replace "Sunset.jpg" and "Mirage.mp3" with your own files.

seconds=443; for x in `seq $seconds`; do cat Sunset.jpg; done | mencoder 
-o out.avi -fps 1 -ovc lavc -demuxer lavf -lavfdopts format=mjpeg 
-audiofile Mirage.mp3 -oac copy -

Note that the example above is a bash shell script, so requires Linux. 
It won't work on MSWindows without alteration. The command "seq 
$seconds" outputs a list from "1" to the number of seconds stored in the 
variable "$seconds". The for... do... done loop cycles  "$seconds" 
number of times  to output the image file (in this case "Sunset.jpg") 
through a pipe (|) to the mencoder command. Notice the final "-" in the 
mencoder command. that takes its input from the standard input, which is 
in this case the pipe (|).

There are some other ways to do this that use just a single image once, 
but you can't seek within the resulting file, can't resize the window 
without losing the image, and can't see the seconds ticking by if you 
use "o" in mplayer to display it. Using the loop to input the original 
image over and over again fixes all those problems, and since it is 
stored as mjpeg the size remains extremely small, since the difference 
between two successive identical images is zero.

Hope this helps,
