    avfilter/f_loop : add time option, for loop start in seconds

  • ffmpeg with delayed inputs put an extra audio output at 0 seconds

    19 mars 2023, par Ralph

    Can someone explain why the input files are played 4 times in total, at 0, 1, 2, 3 seconds.

    


      

    1. The ffmpeg processes three input files (mp3).

      2. 


    2. The complex filter delays the inputs by 1, 2, 3 seconds input-wise.

      3. 


    3. amix mixes the delayed outputs together.

      4. 


    4. And finally, a coded transforms it into an output mp3.

      5. 


    


    ffmpeg -i in0.mp3 -i in1.mp3 -i in2.mp3 -filter_complex "[0]adelay=1000[delayed1];[1]adelay=2000[delayed2];[2]adelay=3000[delayed3];[delayed1][delayed2][delayed3]amix=inputs=3:duration=longest" -codec:a libmp3lame -q:a 4 output.mp3


    


    short version : 2 delayed beeps, an finally there come 3 beeps out (@ 0, 1, 2 seconds) :

    


    ffmpeg -i beep.mp3 -filter_complex "[0]adelay=1000[delayed1];[0]adelay=2000[delayed2];[delayed1][delayed2]amix=inputs=2:duration=longest" -codec:a libmp3lame -q:a 4 output.mp3


    


    ffmpeg version N-110011-gf456c192d9-tessus on a Mac M1.

    


    I added also a silent input file from 0 to 1 seconds without any alteration of the outcome.
I added a silent stream as input as well without improvement. E.g. :

    


    ... -filter_complex "aevalsrc=0:d=4[silence];...


    


    Another test with another ffmpeg version 5.1 Copyright (c) 2000-2022 the FFmpeg developers built with Apple clang version 13.1.6 (clang-1316.0.21.2.5) :
ffmpeg -i beep.mp3 -filter_complex "[0]adelay=1000[delayed1];aevalsrc=0:d=5[silence];[silence][delayed1]amix=inputs=2:duration=longest" -codec:a libmp3lame -q:a 4 output.mp3
There are again 2 beeps, at 0 and 1 second - going mad here !

    


    (concat solves the issue. But I want to have a flexible solution with possibly overlapping audio streams.) Thanks for giving a hint !

    


  • nodejs fluent-ffmpeg split long file into multiple small files based on seconds given

    9 mars 2023, par Mahesh Dama

    I want to split 10 minute audio mp3 file to 10 different 1 minute files using fluent-ffmpeg package in nodejs.
We can do this for ffmpeg package using the following command

    


    ffmpeg -i file.wav -f segment -segment_time 60 -c copy parts/output%09d.wav


    


    But I want the same functionality in fluent-ffmpeg for nodejs. What is the name of the method ?

    


    return ffmpeg(audioFile)
    .toFormat('wav')
    .audioChannels(1)
    .audioFrequency(44100)
    .audioBitrate('128')
    .on('error', (err) => {
        //error
    })
    .on('progress', (progress) => {
        //progress
    })
    .on('end', () => {
      // on complete
    })


    


    I tried looking at documentation for the segment feature for fluent-ffmpeg but couldn't get any solution.
