  • Why my youtube video made with ffmpeg only shows 360P and 1080P on mobile devices but works fine on desktop ?

    1er janvier 2020, par CheeseWithMe

    I am trying to create a video from an image and sound file with ffmpeg.

    This is what I use :

    ffmpeg -y -loop 1 -r 6  -i current_image.png -i current_audio.wav -shortest -c:v libx264 -preset ultrafast -tune stillimage -pix_fmt yuv420p -c:a aac out.mp4

    But uploading this on youtube will display only in 360P and 1080P on mobile devices while on Desktop I have all the resolutions up to 1080P.

    It has the same effect with the command from FFmpeg wiki on enconding from youtube

    ffmpeg -loop 1 -framerate 2 -i input.png -i audio.m4a -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a copy -shortest -pix_fmt yuv420p output.mkv

    I have no idea why is this happening, I could use some guidance.
