  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • FFmpeg can't decode H264 stream/frame data

    31 juillet 2015, par Gediminas

    Recently I had chance to work with two devices that are streaming the H264 through RTSP.
    And I’ve ran into some problem trying to decompress this stream using FFmpeg library.

    Every time the "avcodec_decode_video2" is called - FFmpeg just says something like :

    [h264 @ 00339220] no frame !

    My raw H264 stream I frame data starts like this : "65 88 84 21 3F F8 F8 0D..."
    (as far as I understand this 0x65 indicates that it’s a IDR frame ?)

    Other frames for one device starts like : "41 9A 22 07 F3 4E 48 CC...."

    and for other device - like this : "61 9A 25 C1 1C 45 62 39...."

    • Am I missing some frame data here ?
    • Does FFmpeg needs to have some extra parameters set up ?

    I was expecting at least "00 00 00 01" bytes at the start for the frame data... but this is what I’ve got..

  • Finding start point in audio file with ffmpeg

    4 juillet 2019, par jovadeza

    I’m trying to determine the starting and end point in an audio file with ffmpeg. My definition for start and end point is when the song reaches -27dB. I have tried multiple ffmpeg audio filters, but without the desired result.

    The closest I got was when using the following command :
    ffmpeg -i song.mp3 -af silencedetect=n=-27dB:d=0.2 -f null -

    However, this returns multiple values, since the song can get silent in the middle of the song as well.

    So, I only want to get the first time the song reaches -27dB and the last time the song reaches -27dB.

    See image with example markers, created manually in Adobe Audition. Marker 1 : song reaches -27dB for the first time, marker 2 : song reaches -27dB for the last time. This are the positions in the song I am trying to find, trough ffmpeg

    enter image description here

    Thanks !
