  • FFMPEG libfdk_aac codec with VBR option not supported

    25 septembre 2018, par Piri

    I’m trying to makes an app that uses terminal ffmpeg with libfdk_aac codec.
    The problem is when I use -VBR mode, the result Bit rate mode is always Constant(CBR).

    I’ve searched about this problem and I’ve found the following article :

    https://lists.ffmpeg.org/pipermail/ffmpeg-user/2013-February/013652.html
    this article is from 2013 and seems is still valid !

    Also i am not the only one with this problem
    https://superuser.com/questions/1326239/encoding-aac-from-wav?rq=1

    My terminal string is :

    ffmpeg -i input* -c:a libfdk_aac -vbr 4 output**

    1. *- input formats can be : FLAC, WEBM, MP4
    2. **- output formats can be : M4A, AAC

    Question is : Can this be solved with the current version of ffmpeg :
    ffmpeg version 4.0.2 Copyright (c) 2000-2018 the FFmpeg developers
    built with gcc 7 (Ubuntu 7.3.0-16ubuntu3) ??
    if not, is using directly fdkaac from terminal the only option ?

    Any Help is much appreciated.
