  • Is there any way to combine PNGs as a Quicktime-compatible MP4 from FFMPEG ?

    12 avril 2020, par griffin2000

    Is there any way to get combine PNGs as a Quicktime-compatible MP4 from FFMPEG ?

    



    I'm using this command currently :

    



    ffmpeg -i frame%03d.png -pix_fmt yuv420p  output.mp4


    



    This is the video works fine in VLC and can be uploaded to Youtube/Vimeo/Facebook fine but Quicktime complains that it "cannot be opened" :
enter image description here

    



    A few questions (e.g. https://apple.stackexchange.com/questions/166553/why-wont-video-from-ffmpeg-show-in-quicktime-imovie-or-quick-preview) about this at various sources, but none of the answers seem to work and they all seem to boil to down to some variant of "use yuv420p" or a couple of other flags. None of which seems to work. Apparently it may have changed in later (post-Yosemite) versions of MacOS ?

    



    So what (if anything) is the magic incantation that make this work with later versions of Quicktime ?

    



    Thanks all
