Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

ffmpeg - render multiple audio files on a video [duplicate]
28 février 2018, par J. DoeThis question already has an answer here :
I want to render audio from multiple
.wav
files on an.mp4
file so the out put will be the original video and sound with the audio of the.wav
files on top of it.I’ve read many similar threads in Stackoverflow and nothing worked for me.
This is my latest attempt :
ffmpeg -i original.mp4 -itsoffset 3 -i additional1.wav -itsoffset 5 -i additional2.wav -c:v copy -map 0:v -map 0:a -map 1:a -map 2:a output.mp4
But it doesn’t work

Using ffmpeg to convert video audio and thumbnail in separate threads ?
26 janvier 2018, par Oleksandr KyrpaI converting lot of videos and same time ago, I found what if split converting process to different task then I can speed up total process. Because, for example, ffmpeg process don’t need wait for processing raw data to video decoder if audio frame was readed from input file, just skip this frame.
process1 for video
ffmpeg -i video.mp4 -an -c:v h264 ..... -y out.h264
process2 for audio
ffmpeg -i video.mp4 -vn -c:a aac ...... -y out.aac
process3 for thumbnail
ffmpeg -i video.mp4 -vf fps=1/60 img%03d.jpg
And after all process was completed then I need to marge video and audio tracks in to mp4 container. Using this method I solve bottle neck problem and got seed up total process.
ffmpeg -i out.h264 -i out.aac -c:v copy -c:a copy -y out.mp4
But any other way to speed up convertion in modern ffmpeg ?

TCL script unable to work with multiple camera on windows 7 platform
27 novembre 2017, par M. D. PMy TCL script works properly for single camera. the TCL script is as follow :
proc liveStreaming {} {
#open the config file.
set f [open "C:/main/video_config.txt" r]
#To retrive the values from the config file.
while {![eof $f]} {
set part [split [gets $f] "="]
set props([string trimright [lindex $part 0]]) [string trimleft [lindex $part 1]]
}
close $f
#camera selection to live streaming.
set camera "video"
append cctv $camera "=" $props(cctv)
#ffmpeg command to capture live streaming in background
exec ffmpeg -f dshow -s 1280x720 -i $cctv c:/test/sample.avi >& c:/test/temp.txt &
}
liveStreaming
//above code is to capture video using ffmpeg and tcl.My text file "video_config" is as follow :
cctv=Logitech HD Webcam C525
as, i want it to run with multiple camera : the text file should be as follow :
cctv=Integrated Webcam,Logitech HD Webcam C525
The problem is "," (comma), my TCL script is unable to predict the coma (,) . can any one provide me the proper TCL script which can predict the coma, so that my TCL script can work with multiple camera.
