  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • FFmpeg Convert to JPEG works in VLC but not in Mac Preview ?

    24 juillet 2019, par Evan Keeton

    I’m trying to convert a PNG image to a JPEG image using ffmpeg. As far as I can tell, it’s working fine, but it doesn’t display properly in Mac Preview.

    I’m running the following :

    $ ffmpeg -i foo.png foo.jpg

    And it produces the following output :

    When I open foo.jpg in most applications, such as VLC or Google Chrome, I get exactly what I expected : an image that looks exactly the same as foo.png, the input.

    <code width='200' height='231' / class='spip_code' dir='ltr'>foo.png</code> (input)
    <code width='200' height='231' / class='spip_code' dir='ltr'>foo.jpg</code> (output)

    However, this is what is displayed in the Finder preview, and the same this is displayed when I open up the file in "Preview."

    the problem

     I wonder if this has something to do with the deprecated pixel format used, make sure you did set range correctly error, but I’m not sure, especially since the image is fine, the problem seems to be elsewhere. 

    It seems the deprecated pixel format error is not the issue (that’s an internal thing), so I guess I just need to specify pixel formats properly.

  • FFmpeg is dropping a frame when converting MP4 to image sequence

    24 juillet 2019, par Phillip Dodson

    I have an MP4 file that’s encoded at 12fps that I’m trying to convert to an image sequence using FFmpeg. The issue is that there is one frame missing. I’ve used the solutions here to confirm that the number of frames are 195 but when I run the following ffmpeg -i video.mp4 frames_%04d.png, I only get 194 PNGs. I’ve tried using the -r 12 and -framerate 12 flags but they do not change the output.

    I’ve also run the MP4 through Adobe Media Encoder to create an image sequence and that produces 195 frames. Any thoughts on to why I’m losing a frame ?

  • FFmpeg from Python has Corrupted Output

    14 juillet 2019, par Mazyod

    In a python script, I have :

# also tried Popen(ff_cmd, shell=True).wait()

    Then, I ran that same ff_cmd from terminal directly. Here are the results :

    # ff_cmd
