  • 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 (...)

  • Obtain the total number of samples with FFMpeg

    10 octobre 2018, par Henricus V.

    Currently my application reads audio files based on a while-realloc loop :

    // Pseudocode
    
float data* = nullptr;
    
int size = 0;
    
AVFrame* frame;
    
while(readFrame(formatContext, frame))
    
{
    
    data = realloc(data, size + frame.nSamples);
    
    size += frame.nSamples;
    
    /* Read frame samples into data */
    
}

    Is there a way to obtain the total number of samples in a stream at the beginning ? I want to be able to create the array with new[] instead of malloc.

  • avcodec/aom_film_grain : allocate film grain metadata dynamically

    avcodec/aom_film_grain : allocate film grain metadata dynamically

    This removes the ABI breaking use of sizeof(AVFilmGrainParams), and achieves the
    
same size reduction to decoder structs as 08b1bffa49715a9615acc025dfbea252d8409e1f.
