  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Obtain the total number of samples with FFMpeg

    21 juin 2016, par Henry W.

    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.

    This should reduces the number of uninteresting timeouts encountered

  • Strange FPS and frame number while re-encoding a video

    5 juillet 2017, par mdasari

    I am re-encoding a video using below command :

    ffmpeg -i input.mp4 -q 20 output.avi

    The video is 10 mins approx, i.e, it has around 18K frames. However, I am getting last frame number as 5061, but the re-encoded video is playing for all 10 mins. I don’t understand the reason why it is showing such a low frame number. Below is last few lines of output.
