years ago i wrote a PHP wrapper to get a image with a audio file merged 
and a lot of players did only show a single image and then only the 
audio - in that case "-loop_input -i imagefile" did the trick to repeat 
the image for the full length of audio

the last time i tried this script it did no longer work at all with 
recent ffmpeg but i had no time to look what was wrong - probably 
something else in the generated command line and -loop_input still works
