Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

FFMPEG : Generate 7.1 channel audio file with the longest time of input file
10 juin 2020, par AnthonyI want to use ffmpeg to generate 7.1 channel audio file from 8 different audio files.
But I found the output file's duration is decided by the input file with shortest duration.
I didn't find any parameter to auto-pad the shorter audio file or choose the longest duration as final duration.



I already have seen the offlical document as below.
https://ffmpeg.org/ffmpeg-all.html
https://trac.ffmpeg.org/wiki/AudioChannelManipulation
But nothing is helpful.



This is the command I use right now :



ffmpeg -i fl.wav -i fr.wav -i fc.wav -i lfe.wav -i bl.wav -i bl.wav -i sl.wav -i sr.wav -filter_complex "[0:a][1:a][2:a][3:a][4:a][5:a][6:a][7:a]join=inputs=8:channel_layout=7.1[a]" -map "[a]" output.wav

mmpeg changing the bitrate and file size of resulting file
17 août 2019, par Paco AbatoI’m using
ffmpeg
within a Python script (usingmmpeg-python
) in order to change metadata values but the bitrates and file size are also changed in the resulting video (bitrates are ’Velocidad de datos’ and ’Velocidad de bits’, sorry for non-english GUI) :The command I use is the following (removed the metadata part because the result is the same : the bitrate and the file size being changed) :
import ffmpeg
ifile = 'borrar.mp4'
ofile = 'res.mp4'
ffmpeg.input(ifile).output(ofile).run()How to preserve bitrates and so an aproximate file size.
Thanks in advance.
