Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -
MediaSPIP en mode privé (Intranet)
17 septembre 2013, parÀ partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

how to remove duplicated frame from 00:00:00,00 to 00:00:00,25 section not overall with mpdecimate filter ?
19 octobre 2018, par cool jobshow to remove duplicated frame from 00:00:00,00 to 00:00:00,25 (00frame 25frames)section not overall with mpdecimate filter ??
normally H264 video have some duplicated frames on video start section ..i have tried like this ,
1) ./ffmpeg -i cated_2-3.UMMJI.MTS -map 0:0 -c:v prores_ks -profile:v 1 -qscale:v 8 -s 1920x1080 -r 29.97 -top 1 -c:a pcm_s16le -map 0:1 -filter:a:0 "pan=mono|c0=c0" -map 0:1 -filter:a:1 "pan=mono|c0=c1" -metadata:s encoder="Apple ProRes 422 LT" -filter_complex "[0]split=2[a][b];[a]trim=end_frame=26,mpdecimate[a];[b]trim=start_frame=25,setpts=PTS-STARTPTS[b];[a][b]concat=n=2:v=1:a=0" -vsync vfr -vf blackdetect=d=0.1:pix_th=.1 cated_2-3.UMMJI_MTS_mpdecimate26_section.mov
and tried to check black_frame on out prores mov file
2)./ffmpeg -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov -vf blackdetect=d=0.1:pix_th=.1 test.mov
then , will be shown like below
macmini-master:1. two_file_test khan$ ./ffmpeg -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov -vf blackdetect=d=0.1:pix_th=.1 test.mov

ffmpeg image sequence from text file not rendering correctly
4 juillet 2018, par RichI’ve been working with ffmpeg and I have got it to work perfectly quite a few times, but as of recent I am running into an issue where all the images from my text file arent used.
My text file looks like -
ffconcat version 1.0
file 'gallery-house-77-west-55th-street-01.jpg'
duration 4.44
file 'img03.jpg'
duration 4.44
file 'inside.png'
duration 4.44
file 'placeholder.png'(amount of files, file names and extensions will always vary)
And I’ve tried several combinations but as of now my ffmpeg function looks like —
ffmpeg -i audio.mp3 -safe 0 -f concat -i paths.txt -c:a copy -c:v libx264 \
-vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,fps=25,format=yuv420p" -vsync vfr -movflags +faststart -y output.mp4 2>&1');When trying to run it, the video seems to convert but has various weird behaviors - sometimes only the middle file(image) in the list is shown or the first 2 only are shown/rendered.
The audio is playing correctly though.
I’ve tried setting the framerate for the input and I also tried setting it for the output but it leads to more strange behavior.
This is what is echoed when running my above ffmpeg command -

After some more debugging I think it may be related to the fact that all the files dont have the same extension. How can I make it so that it doesn’t have to be that way or is that already a default setting and the issue is else where ?

Ffmpeg converted videos (longer than 30s) not playing in chrome
3 février 2016, par Razvan IlinAs the title says, I’m having issues with converted videos that are over 30s. They are not playing in chrome but they do work in all other browsers. The thing is, if the video is less than 30s than it plays fine in chrome too.
The input file is
mpeg4
encoded and I’m trying to convert it using theh264
codec. The conversion is done on a linux server with the help of a drupal module which converts the video on upload automatically.This is the command and output :

[libx264 @ 0x38799c0] kb/s:715.83I also tried with the latest version of ffmpeg but I have the same problem.
Does anyone have any ideas on why this is happening ?Note that this is a log from doing a two-pass encoding (it was the only way to get a log from drupal). The two-pass encoding works if I specify a bitrate in the ffmpeg command, but as I said, it doesn’t work on chrome but works on all other browsers.
