You need to add "-loop_input" if the video input is a single frame,
and then you'll also need to add "-t <duration_in_seconds>" to make
ffmpeg finish the encoding because otherwise the looped image input
will run on past the end of the audio stream.

Also, if the audio is already mp3-encoded, it's probably better to use
"-acodec copy" to prevent degradation from re-encoding.

Actually, I'm not sure you need to upload h.264/mp3 to youtube; I'd
certainly try a format with ogg-encoded audio first.
