  • ffmpeg issue after adding background audio

    9 avril 2021, par spicy

    So I have an issue to which I cannot find an answer. I have a video which is 7min 38sec long after concat. When I want to add background audio to this video it cuts off the last 7sec of the original video. I cannot find the reason.

    


    If anyone could help me in any way, it would be amazing because I have been troubleshooting this past 3 days.

    


    My FFmpeg version is ffmpeg version 4.2.3 Copyright (c) 2000-2020 the FFmpeg developers.

    


    For concat I use this : FFmpeg -f concat -safe 0 -i txtfile.txt -c copy -ac 2 output.mp4

    


    For adding background audio I use this : ffmpeg -i output.mp4 -i background.mp3 -c:v copy -filter_complex "[0:a]aformat=fltp:44100:stereo,apad[0a];[1]aformat=fltp:44100:stereo,volume=0.2[1a];[0a][1a]amerge[a]" -map 0:v -map "[a]" -ac 2 -shortest output_with_background.mp4

    


    And the console output while doing its stuff is :
