  • Using ffmpeg to create looping apng

    5 décembre 2024, par Harry

     ffmpeg -ss 16:43 -i ./10.mkv -loop 10 -t 1 -filter:v "setpts=PTS-STARTPTS, crop=1200:800, hqdn3d=1.5:1.5:6:6, scale=600:400"  10-file-2.apng


    



    I've tried -loop -1 -loop 10 -loop 1 but there is no looping done. My version is

    



    


    ffmpeg-3.3.el_capitan.bottle.tar.gz
