I have a MKV video consist of a video and an audio of duration 10 minutes, after using ffmpeg to extract ac3 to aac audio, its duration became 10:50, which lead to audio out of sync with the video after packaging the new extracted audio to mp4 container using mp4box. how to solve the problem of syncing or as i knew, the delay that happen with aac encoding ? commands:
ffmpeg -i "d:/input.mkv" -vn -c:a aac "d:/audio.aac"
MP4Box
-add "C:/1280x720.264"
-fps "23.976023976024"
-add "d:/audio.aac:lang=ara"
