FFMPEG を使ってmp3からTwitterで使うmp4を作る (1枚の静止画を使って)
# width not divisible by 2 というエラーが出る場合は -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" を追加する
ffmpeg -loop 1 -i blue.jpg -i ~/Desktop/aa.mp3 -shortest -b:a 320000 -pix_fmt yuv420p -vcodec libx264 out.mp4
# そもそもアップロードできない
# ffmpeg -loop 1 -i black.jpg -i input.mp3 -shortest -b 1000k -vcodec libx264 out.mp4
# これだとtwitterでは音がきこえなかった
# ffmpeg -loop 1 -i black.jpg -i input.mp3 -shortest -b 1000k -acodec copy out.mp4
