如何为ffmpeg安装“ dynaudnorm”音频过滤器

Question

I am running linux Mint 17 64 bits-kernel 3.13-generic, with the ffmpeg version:

ffmpeg version 2.4.3-1ubuntu1~trusty6 Copyright (c) 2000-2014

I need to run the 'Dynaudnorm' audio to compress audio files in a daily basis. But launching

ffmpeg.exe -i "in_original.wav" -af dynaudnorm "out_normalized.wav"

gives:

[AVFilterGraph @ 0x1efe820] No such filter: 'dynaudnorm'

The filter developer site explains that the integration in ffmpeg it's already done for the latest binaries, but in my version (update yesterday) doesn't show.

It's only Windows available?

Answer 1

Your ffmpeg version is very old. Get a static build of the git build from https://www.johnvansickle.com/ffmpeg/

Answer 2

Windows

• Download the ffmpeg binaries from zeranoe .
• Extract the archive file.
• Copy the contents of the bin folder to System32 .

Linux

On linux distributions use the terminal to download binaries!
I don't recommend to compile it yourself!

# On Fedora, use yum
sudo yum install -y

# On Ubuntu, Linux Mint, Debain
sudo apt install ffmpeg -y # Or,
sudo apt-get install ffmpeg -y

Or, manually compile it using the CompilationGuide .
