  • 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. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.
    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 (...)

    avcodec/prores_aw : change src pix_fmt and alpha description

    use b64a as src pix fmt (doesn't seems to have an impact on decoding)
    
but it's the value use by official encoder

  • Limit file size in FFmpeg

    26 novembre 2019, par Arete

    The official documentation for FFmpeg says :

    -fs limit_size (output)

    Set the file size limit, expressed in bytes. No further chunk of bytes is written after the limit is exceeded. The size of the output file is slightly more than the requested file size.

    This is very confusing. If the file size is slightly more than the requested file size then I have the following questions :

    1. What determines how much more (than the requested file size) the file will consume ?

    2. How much more will the file exceed the requested file size ?

    3. Is there any way to set the file size exactly ?

    4. What is the point of having the -fs if it does not actually work ?

  • ffmpeg make video from multiple images and one audio with specific timestamps for each image [closed]

    2 juin 2024, par Trojosh

    I have an audio file and I have 15 images. I would like to make a video from these 15 still images. Each image may appear for different number of seconds.
E.g. Image 1,2,3 will take 3 seconds each but image 4 may take 40 seconds because it is more complex.

    


    How can I use ffmpeg to specify timestamp for each image and add audio to the same.

    


    Also note that the sum of timestamps of all images = running time of the audio.

    


    I looked at this question and image2 filter option from the official documentation but no luck in producing such a video
