  • How to display a frame number on each frame of a video using ffmpeg ?

    11 mai 2022, par igorg

    The test command I have is as follows :

    



    ffmpeg -i in.mov -vf "drawtext=fontfile=/usr/share/fonts/ttf-bitstream-vera/Vera.ttf: x=(w-tw)/2: y=h-(2*lh)-n: fontcolor=white: fontsize=40: box=1: boxcolor=0x00000000@1: text=" -an -y out.mov


    



    I want to display the frame number on each frame. However, setting the "text" variable to "n" does not help (it displays n) and %n seems to be the new line symbol. The thing that confuses me most is that this part

    



    y=h-(2*lh)-n


    



    works well, meaning it gets the right value of the current frame and moves the text up accordingly.
