Bash script using FFMPEG to automatically convert audio-only podcasts to a solid video file using a cover image for YouTube

• Add the audio files (.wav, .aif or .mp3) to the /audio/ folder
• Add the images as a .png to the /img/ folder.
• Make sure the images have the same name as the corresponding audio file, (I use 001.mp3 to match with 001.png).
• Install FFMPEG, preferably via Homebrew.
• run ./audio-to-video.sh in the root folder.
