  • FFMPEG blending screen two libvpx-vp9 webm yuva420p video files comes out looking incorrect

    30 novembre 2022, par OneWorld

    I'm trying to screen blend two libvpx-vp9 webm files, so that the blend comes out looking correct in FFMPEG. The example below takes two rgba png input files, loops them for a couple of seconds into libvpx-vp9 webm files with the pixel format yuva420p. It then tries to blend them using FFMPEG. I then output frames of these to visualise how it looks here in this Stack Overflow post.

    


    I have these two input rgba pngs (circle and Pikachu)

    I create two libvpx-vp9 webm files from them like this :-

    


    ffmpeg -loop 1 -i circle_50_rgba.png -c:v libvpx-vp9 -t 2 -pix_fmt yuva420p circle_libvpx-vp9_yuva420p.webm

ffmpeg -loop 1 -i pikachu_rgba.png -c:v libvpx-vp9 -t 2 -pix_fmt yuva420p pikachu_libvpx-vp9_yuva420p.webm


    


    I then try and do a blend of these two libvpx-vp9 webm files like this :-

    


    ffmpeg -y -c:v libvpx-vp9 -i circle_libvpx-vp9_yuva420p.webm -c:v libvpx-vp9 -i pikachu_libvpx-vp9_yuva420p.webm -filter_complex "[1:v][0:v]blend=all_mode=screen" pikachu_reverse_all_mode_screened_onto_circle_both_yuva420p.webm


    


    and extract a frame from that like this

    


    ffmpeg  -c:v libvpx-vp9 -i pikachu_reverse_all_mode_screened_onto_circle_both_yuva420p.webm -frames:v 1  pikachu_reverse_all_mode_screened_onto_circle_from_yuva420p.png


    


    Which looks like this :-
enter image description here

    


    If I do this without all_mode, like this

    


    ffmpeg -y -c:v libvpx-vp9 -i circle_libvpx-vp9_yuva420p.webm -c:v libvpx-vp9 -i pikachu_libvpx-vp9_yuva420p.webm -filter_complex "[1:v][0:v]blend=screen" pikachu_reverse_screened_onto_circle_both_yuva420p.webm


    


    and then extract the png so we can visualise it, like this :-

    


    ffmpeg  -c:v libvpx-vp9 -i pikachu_reverse_screened_onto_circle_both_yuva420p.webm -frames:v 1  pikachu_reverse_screened_onto_circle_from_yuva420p.png


    


    it gives this output :-
enter image description here

    


    which is also incorrect because the white part of the circle should be completely white in the screen blend. We shouldn't see a faint yellow outline of Pikachu inside the white part.

    


    It should look like this :-

    Here is the full log of this is like this :-

    


    ffmpeg -y -c:v libvpx-vp9 -i circle_libvpx-vp9_yuva420p.webm -c:v libvpx-vp9 -i pikachu_libvpx-vp9_yuva420p.webm -filter_complex "[1:v][0:v]blend=screen" pikachu_reverse_screened_onto_circle_both_yuva420p.webm

    I also tried doing a convertion to rgba, like this :-

    


    ffmpeg -y -c:v libvpx-vp9 -i circle_libvpx-vp9_yuva420p.webm -c:v libvpx-vp9 -i pikachu_libvpx-vp9_yuva420p.webm -filter_complex "[0:v]format=pix_fmts=rgba[zero];[1:v]format=pix_fmts=rgba[one];[one][zero]blend=screen" pikachu_reverse_screened_all_mode_onto_circle_after_rgba_conversion_webm.webm


    


    However the result of this also comes out with yellow inside the white circle, which should be white

    


    I was wondering what I need to do so that the blend of these two webm libvpx-vp9 video files looks correct, like it does above.

    


    note : I need to retain the alpha channels, because sometimes assets have transparent alpha channels. In the examples above the assets happen to have opaque alpha channels.
