drawtext filter

If you just want to update some text on the screen the easiest method is to use the drawtext filter with the textfile and reload options.

ffmpeg -i input -vf "drawtext=textfile=songs.txt:reload=1" output songs.txt will be reloaded once per frame. Be sure to update it atomically, or it may be read partially, or even fail.

overlay filter
