  • Taille des images et des logos définissables

    9 février 2011, par

    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes.

    Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...)

  • Add background nusic after every 5 seconds in .mp3 file using ffmpeg

    6 mars 2014, par user3354679

    I want to add background music after every 5 seconds in .mp3 file using ffmpeg.

    I have 2 audio files : input1.mp3 of 5 seconds and input2.mp3 of 4 minutes 04 seconds. I want to add input1.mp3 after every 5 seconds in input2.mp3 like after 0,5,10,15,20,... seconds.

    I am using :

    ffmpeg -i input1.mp3 -i input2.mp3 -filter_complex amix=inputs=2:duration=first:dropout_transition=3 OUTPUT.mp3

    The command is working properly. Can anyone tell me how can i repeat the input1.mp3 after every 5 seconds to input2.mp3 ?

    How can i do it ? Please help me...

  • 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.

  • Removal of Human Voice from a video or audio file

    12 février 2014, par naveen

    Is there a way by which i can remove the human voice from a audio/video. So ultimately the music is left on it.

    I want to do this using any software like adobe etc or with command line like ffmpeg/sox.

    But i prefer command line for tuning up the settings easily.
