kandi X-RAY | ffmpeg-normalize Summary
A utility for batch-normalizing audio using ffmpeg. This program normalizes media files to a certain loudness level using the EBU R128 loudness normalization procedure. It can also perform RMS-based normalization (where the mean is lifted or attenuated), or peak normalization to a certain target level. Batch processing of several input files is possible, including video files. Read on for more info.

QUESTION
I have wav files I am normalizing with ffmpeg-normalize (a python program). My batch file is this
for %%n in (*.wav) do ffmpeg-normalize "%%n" -nt peak -t 0 -o "%%n-norm.wav"
In my directory of 5 files, I get 5 -norm.wav files. Unfortunately then, the batch file creates 5 -norm.wav-norm.wav files and so on and so on. Why wouldn't it stop at the original list of 5 files?
...ANSWER
Answered 2019-Dec-25 at 13:32I think the problem is that a standard for
loop does not fully enumerate the target directory in advance (see also this related thread), and that the output files also match the pattern (*.wav
) for the input files. The first issue could be solved by using a for /F
loop that parses the output of the dir
command, so the complete file list is generated before looping even starts; the second issue could be solved by an additional filter constituted by findstr
to exclude output files to become reprocessed (when the script is executed more often than once):
QUESTION
I am currently working on a script to help me batch convert and normalize audio files (wma to mp3) In the search of useful tools I was lucky to stumble on FFMPEG-Normalize!
My script is running from Python and I am calling FFMPEG via subprocess. I could not get the FFMPEG-Normalize to output Mp3 files - thus I am doing another FFMPEG call to convert the resulted wav files. Do you know how to make FFMPEG normalize also convert to mp3 ? The second issue is that only part of the files in my folder are being processed, I cant understand why. Out of 8 files I have in the path, sometimes all of them are processed and sometimes only 3, or 5... very weird! Here is my code :

Answered 2017-Nov-09 at 08:26The ffmpeg-normalize
tool allows you to set an audio encoder as well, using the -a
, --acodec
option.
For example, to EBU R128-normalize a bunch of WAV files and encode them to MP3 with libmp3lame

...ANSWER
Answered 2017-Jun-20 at 13:12The opencv-python
Windows packages ship with FFmpeg by default. You can have a look at C:\ProgramData\Anaconda3\lib\site-packages\cv2
and you should find FFmpeg DLL there. You don't have to install it separately.
The real problem lies most probably in Anaconda because they are not shipping python3.dll
with their distribution. This is required by PEP 384. Related Anaconda issue is here: https://github.com/ContinuumIO/anaconda-issues/issues/1394
To fix this, you will have to copy python3.dll
from a CPython installer package and place it to PATH. The CPython version must match your Anaconda version. Easiest way is to copy the file to some place which is already in PATH. This could be for example C:\Anaconda3
if that's where your Anaconda installation is located.
If the above does not work, make sure that you have Visual C++ redistributable 2015 installed: https://www.microsoft.com/en-us/download/details.aspx?id=48145
QUESTION
I am trying to pip install ffmpeg-normalize in Python 3.6.1. This used to work fine in Python 2.7.13 but not in the latest version, it seems.
In an elevated command prompt i type: pip install ffmpeg-normalize
I continue to get Command "python setup.py egg_info" failed with error code 1
for some reason and I am not sure what this means...
ANSWER
Answered 2017-Apr-02 at 15:08This looks like a bug in setup.py
to me. Since the default encoding used in python 3 when opening a file in text mode is platform-dependent, an encoding should be explicitly provided. Otherwise the result of a read
operation will be unpredictable and it will fail if the default encoding can't handle the file's content, as happened in your case.
You should be able to fix it by checking out the source code and changing this line:

Answered 2017-Mar-05 at 00:48This could be happening for a few reasons. Here are my guesses :)
How do you know the package isn't being installed? Can you share the docker build output that happens when you gcloud app deploy
?
Another thing to try here, just to be sure is to run:
