Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -
Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).

Concatenate multiple WAV files using single command, without extra file [migrated]
24 avril 2013, par ManuI want to concatenate multiple WAV files into a single WAV file using FFMPEG.
I have used the following command and it generates the required file.
Command :
ffmpeg -f concat -i mylist.txt -c copy output.wav
File :
#mylist.txt
file '1.wav'
file '2.wav'
file '3.wav'
file '4.wav'But as you can see the problem is that I have to create a text file to specify the list of WAV files to concatenate.
I can do all these tasks, but I would prefer a single command something that looks like
ffmpeg -i 1.wav -i 2.wav -i 3.wav -i 4.wav output.wav
or
ffmpeg -i "concat:1.wav|2.wav|3.wav|4.wav" -c copy output.wav
I have tried these two simple commands but they return just the voice of
1.wav
Please help me write a single command( or correct the above 2 commands ) that achieves the desired result.Please don't suggest other Media Encoders/Editors, I want to use FFMPEG only, as it is already installed and used at other places.

libav gives audio duration as negative
5 novembre 2016, par AmitI am trying to make a simple av player, and in some cases I am getting values correctly as below :
checking /media/timecapsule/Music/02 Baawre.mp3
[mp3 @ 0x7f0698005660] Skipping 0 bytes of junk at 2102699.
dur is 4396400640
duration is 311However, in other places, I am getting negative durations :
checking /media/timecapsule/Music/01 Just Chill.mp3
[mp3 @ 0x7f0694005f20] Skipping 0 bytes of junk at 1318922.
dur is -9223372036854775808
duration is -653583619391I am not sure what’s causing the duration to end up negative only in some audio files. Any ideas to where I might be wrong are welcome !

avformat/rmdec : Fix memleaks upon read_header failure
20 juillet 2020, par Andreas Rheinhardtavformat/rmdec : Fix memleaks upon read_header failure
For both the RealMedia as well as the IVR demuxer (which share the same
context) each AVStream's priv_data contains an AVPacket that might
contain data (even when reading the header) and therefore needs to be
unreferenced. Up until now, this has not always been done :The RealMedia demuxer didn't do it when allocating a new stream's
priv_data failed although there might be other streams with packets to
unreference. (The reason for this was that until recently rm_read_close()
couldn't handle an AVStream without priv_data, so one had to choose
between a potential crash and a memleak.)The IVR demuxer meanwhile never ever called read_close so that the data
already contained in packets leaks upon error.This patch fixes both demuxers by adding the appropriate cleanup code.
