  • 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 (...)

  • ffmpeg throw a silent video output when trying to merge video and audio

    31 janvier 2023, par porororo

    I tried to combine mp4 format video and wav format audio.
The video is shorter than the audio and start second is same as 00:00.

    


    I used command as bellows :

    


    ffmpeg -i video.mp4 -i audio.wav  -filter_complex "[0:a]volume=0.2[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y -shortest output_video.mp4


    


    The problem is the output_video.mp4 is a silent video without the sound.

    


    How can I get the output_video.mp4 with sound from audio.wav ?

    


    ffmpeg output is :

  • ffmpeg and php does not end the conversion

    23 juin 2016, par Fernand Royale

    I’m going crazy with it and do not think the solution.

    I use this code to convert videos, but the conversion did not terminate. I tried several times and stops at different points.

    echo "Starting ffmpeg...\n\n".'';
    
echo shell_exec('/usr/src/ffmpeg/ffmpeg/ffmpeg -y -i movie.mp4 -i logo.png -filter_complex "overlay=10:10" -b:v 1500k -vcodec libx264 movie2.mp4 2> out.txt').'';  
    
echo "Done.\n";

  • FFMPEG command works on Mac but not on Windows [duplicate]

    24 décembre 2019, par Arthur

    This question is an exact duplicate of :

    Hi I’m working on a project which needs to create animations by playing 2000 charts in 50 fps using FFMPEG, the command is :

    ffmpeg -y -framerate 50 -i img-%04d.png -vb 40M -vcodec h264 esez.mp4

    charts are located in the same folder with name as img-0001.png img-2000.png

    It worked well on my Mac. On Windows, the command can run and generate a mp4 file. But the animation is just black screen on Windows media player. I also tried open with VLC, it has some image, but not proper at all.
