  • Ffmpeg converts video of double size of original video with second part without audio

    21 janvier 2020, par mridul4c

    I am converting some videos with below command in ffmpeg

    ffmpeg -y -i source.mp4 -c:a libfdk_aac -ac 2 -ab 128k -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -crf 18 -b:v 4000k -maxrate 4000k -bufsize 4000k -vf "scale=-1:1080" destination_1080.mp4

    But in some cases the output video is exactly double size of the original and the second part is without audio. Please help.
