    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

    10 janvier 2014, par Sotiris Akis Mitracos

    I've installed FFMPEG on my Centos6 vps using this guide

    https://trac.ffmpeg.org/wiki/CentosCompilationGuide

    the result is that now i cannot use the library under apache because it can be used only by root...is there a way to extend permission to all users, or how can i remove and install it for user purpose ?

    thank you

  • How to use Mozilla DeepSpeech to generate subtitle from video file ?

    31 mars 2022, par SingularitySG

    I'm currently trying to generate subtitles file .srt using Mozilla DeepSpeech libraries.

    


    Confusion I'm having :

    


    I'm following this guide but I'm completely lost at the part where he uses pyAudioAnalysis to trim out the silence portion of the .wav files.

    


    Another is the portion where he processes the audio file via calling the ds model & ds scorer
I've downloaded both deepspeech-0.9.3-models.scorer and deepspeech-0.9.3-models.pbmm from https://github.com/mozilla/DeepSpeech/releases Do I just reference the model and scorer to the downloaded file path instead ?

    


    def ds_process_audio(audio_file, file_handle): 
    ds = Model(ds_model)
    ds.enableExternalScorer(ds_scorer)


    


    At the moment, I'm able to extract out .wav files from .mp4, .mkv video format.

    


    I've tried pip install pyAudioAnalysis but I'm not sure how to call the functions that are related to it as per his guide in trimming out the silence portion of the .wav file. Below is the code I'm currently working with as of now.

    


    video_name = "Videos\Gintama_EP342.mkv"
audio_name = video_name + ".wav"


def extractAudio(input_file, audio_file_name):
    # Extract audio from input video file and save to audio/ in root dir
    # Args:
    #    input_file : input video file
    #    audio_file_name : save audio WAV file with same filename as video file

    command = ["ffmpeg", "-hide_banner", "-loglevel", "warning", "-i", input_file, "-ac", "1", "-ar", "16000", "-vn", "-f", "wav", audio_file_name]    
    try:
        ret = sp.call(command, shell=True)
        print("Extracted audio to audio/{}".format(audio_file_name.split("/")[-1]))
    except Exception as e:
        print("Error: ", str(e))
        exit(1)


    


    Appreciate any help given. Thank you

    


  • Show motion compensated images in ffmpeg

    29 novembre 2017, par igon

    This guide shows how to visualize with FFmpeg interesting features (quantization parameters, motion vectors, ...) of an encoded video. One things that I find missing is a way to show motion compensated frames and/or residual frames.

    Is this information exposed by encoders ? Is there a way to visualize it ?
