Convert mp3 -> Video with static image ( ffmpeg/libav & BASH )
Solution 1
First of all, I would highly recommend you to update ffmpeg to a newer version. You are currently using v1.2.6-7, but as we speak, the current version is 2.3.3.
Here is a working command (see ffmpeg wiki):
ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:a copy -c:v libx264 -shortest out.mp4
Also, you could optimize overall weight by reencoding audio if you're using raw sound (aiff or wave) as input:
ffmpeg -loop 1 -i image.jpg -i audio.wav -c:a aac -ab 112k -c:v libx264 -shortest -strict -2 out.mp4
For further reading, see this related stackoverflow post.
Solution 2
ffmpeg -loop 1 -i image.jpg -i audio.mp3 -shortest -c:v libx264 -c:a copy result.mkv
works with version 3.4.2

Some years ago I used the following bash script to get a video out of mp3's and one image (so the image in the video was freezed over the length of the mp3), which worked out fine.
i=0; for file in *.mp3; do i=$((i+1)); ffmpeg -loop 1 -shortest -y -i image.jpg -i $file -acodec copy -vcodec libx264 $file.flv; done
Now I wanted to use this again for doing the same.
Problem:
It does not stop converting at the end of the mp3. Means the current mp3 file eg. has a length of 3 minutes and the script converts until forever or I stop it, so the length of the flv is much bigger than 3 minutes.
(ffmpeg is installed, but with libav the same happens)

Max almost 10 yearsThanks mrgnou. Version 1.2 is what you get by installing through the ppa mentioned on ffmpeg.org (launchpad.net/~jon-severinsson/+archive/ubuntu/ffmpeg).

neoDev about 8 years@gnou The mp4 does not work on iphone... please help
-
gnou about 8 years@neoDev You need to encode the audio channel in aac in that case, so use aac audio codec or libfdk_aac for a better quality (if your ffmpeg is compiled with it).

ESP32 over 5 yearsWorks well, but very slow (about real time for a still image). Why?

ESP32 over 5 yearsIn the end I get a 400 MB file from a 30 min mp3 (20 MB) and a still image.

SuperMar1o over 3 yearsPro-Tip. The smaller the image you use as your "Image" file, the faster the conversion will be. I am using a 1px by 1px white image and getting 700x speedup. Also, filesize is very similar. For example, a 37mb m4a becomes a 38.5mb mp4. However, if you are doing this for YouTube, they do not like a 1px white image lol. So I opted for a 640x400 minimalist wallpaper (10KB) and am getting 60x. Good enough for now.
