This is a very broad request. On this mailing list we can help you with the audio to video part using ffmpeg (unscripted), but not the rest. Some basic examples:

Combine image and audio:
ffmpeg -loop 1 -i image.png -i audio.mp3 -vf format=yuv420p +movflags faststart -shortest output.mp4

Make video from a filter such as showwaves:
ffmpeg -i input.wav -filter_complex "[0:a]showwaves=s=1280x720:mode=line:rate=25,format=yuv420p[v]" -map "[v]" -map 0:a +movflags faststart output.mp4
