  • 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.

  • Use argument shortest in C++ code in FFMPEG

    7 juillet 2021, par Little Max

    I need to set up the argument "-shortest" but in c++ code. I know that I can set up an argument with value for example :

    


     av_opt_set(codecContext, "crf", "28", 0);


    


    But here is the thing, there is a value, but in shortest no value.
So how can I set up shortest in c++ code

    


    Thanks in advance

    


  • How Do I Convert a yuv420 Video File to 16-bit (using ffmpeg) ?

    1er novembre 2022, par IanMurphy

    As the title says, my video file has 12-bit depth and I want to convert it to 16-bit. I dont care which yuv pixel format, as long as its 16 bit. I have installed ffmpeg and I can't figure out what combination of arguments to use to convert it. The video file is very small : 20 frames at 352x288.

    


    This is the command I have been trying, but the file size is the same number of bytes as the original :

    


    ffmpeg -video_size 352x288 -pixel_format yuv420p -sample_fmt s16 -i inpput.yuv output.yuv


    


    If there is another way to do this without ffmpeg, I am open to any suggestions. Thanks in advance !

    


  • Superimpose audio track on plot animation

    17 février 2023, par Antoine101

    I plot a matrix in a standard matplotlib figure with imshow. Each matrix is the result of a signal processing calculation on a time signal snapshot (0.2s). I plot each snapshot one after the other (the signal is several seconds long) in a loop and record the animation with FFMPegWriter, setting the FPS so that it matches real time. The output is an MP4 file.

    


    Now, I'd like to add a soundtrack on top of it, of the time signal that was used to calculate the matrices.

    


    How would you do that ? I scrolled a lot but didn't find any suitable solution.
Any idea of libraries or packages ?

    


    Many thanks in advance.
