To make a video from a single image you'll need to loop it, provide a
not-too-low frame rate, and a duration:

ffmpeg -loop 1 -framerate 10 -t 5 -i input.jpg -vf format=yuv420p
output.mp4

If the duration is long you can save a little time by using a low input
-framerate then change the output frame rate with the -r output option
or fps filter with a more common rate.

Your Android player will require "-vf format=yuv420p" (or the "-pix_fmt
yuv420p" alias) but YouTube will not.
