  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • 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.

  • How do I change audio language using ffmpeg in video files contaning two or more audio tracks

    19 mai 2020, par warezsoftwarez

    I am transcoding video files, that contain 2 audio tracks - Polish and English. Unfortunately my transcoder messes somehow with metadata, and at the output, when I'm checking video file using MediaInfo, i see that both audio tracks are described as English. I'd like to change description of 1st audio track to Polish, so accordingly to ffmpeg documentation :

    



    To set the language of the first audio stream:
ffmpeg -i INPUT -metadata:s:a:0 language=eng OUTPUT


    



    Unfortunately, running command :

    



    ffmpeg -i INPUTPATH -metadata:s:a:0 language=pol OUTPUTPATH


    



    to overwrite input file resulted in saving file thats size is 63KB but it is described as Polish audio (no second audio track - English somehow was deleted)

    



    When I used this command, to save output file as another file, to avoid overwriting if something misses (which is current situation), but using parameter -metadata:s:a:4 because I thought that maybe I'm reading metadata from ffmpeg incorrectly, it resulted in saving output file as 800Mb with only English (no Polish track).

    



    I don't know what should I change in this command to run as I want it to - just changing metadata of first audio track language to Polish.

    



    Here is full ffmpeg output :

    



    C:\Users\user>ffmpeg -i F:\Path\33244813_6000_1_trailer.mp4 -metadata:s:a:4 language=pol F:\Path\testtest.mp4

  • FFmpeg return 'invalid argument' only for some runs, even tought is the same code

    20 septembre 2021, par Gustavo Marinho

    I have a code in python where i need to use FFmpeg to merge a audio and a video downloaded using pytube together :

    


            for video in p.videos:
            video.streams.filter(file_extension='mp4',resolution='480p')[0].download(parent_dir+'/mp4/processing/video')
            print(video.streams.filter(only_audio=True)[1].download(parent_dir+'/mp4/processing/audio'))

            subprocess.run([

                r'c:\FFmpeg\bin\ffmpeg', '-i',
                os.path.join(parent_dir+'/mp4/processing/video',video.streams.filter(file_extension='mp4',resolution='480p')[0].default_filename)
                ,'-i',
                os.path.join(parent_dir+'/mp4/processing/audio',video.streams.filter(only_audio=True)[1].default_filename),
                '-c:v','copy','-c:a','copy',
                os.path.join(parent_dir+'/mp4',video.streams.filter(file_extension='mp4',resolution='480p')[0].title+'.mp4')

            ])


    


    I tought the code was working perfectly, but in some cases, the FFmpeg returns "invalid argument", like this example :

    For some reason, the FFmpeg say that my output name is invalid, but i don't understand why, given that i ran the code multiple times before and it worked perfectly

    


    Thanks in advance, sorry for my bad english :3

    


  • Laravel FFMpeg - FFMpeg cannot edit existing files in-place
