  • 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 (...)

  • getting errors from FFMpeg when spawned from .NET

    18 mars 2014, par Brannon

    When I run FFMpeg from the command line like this

    ffmpeg.exe -hwaccel auto -re -i "C:\Users\Public\Videos\Sample Videos\Wildlife.wmv" -an -sn -c:v bmp -pix_fmt bgr24 -f rawvideo - > junk.bin

    it works fine. However, when I spawn the exact same thing (minus > junk.bin) I get this nasty "bad header" error after a few seconds of playback. What is causing this ? I have trouble believing my process blocks the pipe longer than the filesystem does, but it should be able to block the pipe indefinitely without defeating the decoding. The truncated stderr is below. My code to spawn the thing is here.

    26 février 2014, par YorgZ

    I am trying to use ffmpeg to stream video using ffserver. You will find below the ffserver1.conf file, and the log output from the ffmpeg command.

    One of the errors references presets, and everytime I try to use presets I get the error "File not found, even after copying all the preset files in the current directory.

    Thanks for the help.
