  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La 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).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

    • [DH] configure
  • Quick stream from file which exists

    4 mai 2017, par parsa

    I implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
    When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
    I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
    Here is my ffmpeg code for streaming :

    ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8
                 -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8
                 -s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8
                 -s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
                 -s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8

    And here is the console output :

       ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil

    But I don’t have any problem for streaming files with creating resolutions from a file which have lower orginal quality than hd1080
    What I can to do ?

  • FFmpeg error : ratecontrol_init : can't open stats file

    18 décembre 2015, par oldo.nicho

    I’ve setup an AWS EC2 instance running Ubuntu 14.04 and have installed FFmpeg so that I can compress and transcode video.

    I’m trying to do a two pass conversion with the following code :

    ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 1 -an -f mp4 ~/encoded/null

    and second pass :

    ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 2 -codec:a libfdk_aac -b:a 128k -f mp4 output-file.mp4

    However I get the following error :

    The command as written above works fine on my local computer (running OSX). Would anyone have any suggestions as to how to fix this problem ?
