  • Recording desktop with gdigrab ffmeg to mp4 file with too high video_size don't working

    22 septembre 2021, par tagry

    I try to recording my desktop with ffmpeg using the command :

    



    ffmpeg -f gdigrab -framerate 10 -video_size 1920x1200 -i desktop -pix_fmt yuv420p -vcodec libx264 -preset ultrafast output.mp4


    



    The problem is when the video_size option is higher than some size, (for example height higher 1089), the video can't be read with Windows Media. I noticed that with this high size, the video which be recorded doesn't have informations about size. I don't understand why the record don't work with a too big size. If somebody can help me. 
Thank you very much and very sorry for my English.
