  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • encode x264(libx264) raw yuv frame data

    26 juin 2015, par Mohamed El-Sayed

    I am trying to encode an MP4 video using raw YUV frames data, but I am not sure how can I fill the plane data (preferably without using other libraries like ffmpeg)

    The frame data is already encoded in I420, and does not need conversion.

    Here is what I am trying to do :

    const char *frameData = /* Raw frame data */;
    

    
x264_t *encoder = x264_encoder_open(&param);
    
x264_picture_t imgInput, imgOutput;
    
x264_picture_alloc(&imgInput, X264_CSP_I420, width, height);
    

    
// how can I fill the struct data of imgInput
    

    
x264_nal_t *nals;
    
int i_nals;
    
int frameSize = x264_encoder_encode(encoder, &nals, &i_nals, &imgInput, &imgOutput);

    The equivalent command line that I have found is :

     x264 --output video.mp4 --fps 15 --input-res 1280x800 imgdata_01.raw

    But I could not figure out how the app does it.

    Thanks.

  • using ffmpeg to convert raw audio data to wav file

    10 juillet 2017, par ingeniouslyfowl

    I have a text file that contains some raw data that I generated from a wav file. I read in a signal from the wav file, and then used

    fid = open("test.raw", 'write')
    fid.write(data.tostring())

    to write the raw data to a file. Currently, I’m doing this because I want to be able to append to this file as needed without having to change header information. I’m not concatenating multiple audio files, just processing parts of a signal and I don’t want to have a potentially enormous signal in memory. When I try to use ffmpeg to convert this data using

    ffmpeg -i test.raw output.wav

    I end up getting the error : test.raw: Invalid data found when processing input. I’ve also been going through the ffmpeg docs but nothing I’ve tried seems to be working.
