FFMPEG libfdk_aac codec with VBR option not supported
25 septembre 2018, par PiriI’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=1My terminal string is :
ffmpeg -i input* -c:a libfdk_aac -vbr 4 output**
- *- input formats can be : FLAC, WEBM, MP4
- **- 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.
