  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • Set timeout on ffmpeg process

    30 octobre 2013, par Thomas Vervik

    Sometims ffmpeg never completes, and thereby preventing conversions of other videos in the queue. Is it possible to set some sort of timeout in ffmpeg such that it terminates if it isnt finished within some given time, example 5 min

    My command looks like this today :

     ffmpeg -i /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141 -y -r 24 -ar 22050 -f mov -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.mov -ar 22050 -b 1500k -vcodec libtheora -acodec libvorbis -f ogg -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.ogg -ar 22050 -vcodec libx264 -profile baseline -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141_mp4.mp4

    UPDATE. Thanks LordNeckBerd, you pointed me in right direction !

    So I see now its kind of not ffmpeg really hanging, the issue is that my java code which reads the inputstream from the linux process will block since ffmpeg never returns a end of line, which I see now when Im running the command. This is the blocking line, it waits for more input from me.

    Press [q] to stop, [?] for help

    So its two issues here now. First is why this particular conversion is failing, and second, how to make sure ffmpeg is not making this (for my Java process) blocking command asking for more input.
