  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

    Make sb intra rd search consistent with encoding

    This commit makes operations of the superblock intra coding rate
    distortion optimization consistent with those used in the encoding
    process. Given the test prediction mode and transform size, the rd
    optimizer encodes and reconstructs each transformed block of the
    superblock consecutively, then computes the total rate-distortion
    costs accosicated with the current superblock to select the coding
    decisions.

    It achieves coding performance gains :
    derf 0.353%
    yt 1.111%

  • Change in MP4 duration from actual Video duration

    30 avril 2013, par Jayanth Nayak

    I have muxed a 10s H.264 video with 10s aac audio using FFMPEG into a mp4 container. But the total duration showed by VLC Player is 14seconds, any idea why this might happen ?

  • using ffmpeg as multiple downloads

    26 avril 2013, par user2321982

    well guys, I'm having problems with my application.
    well I'll explain more, I'm using the plugin uploader uploads multiple videos and I'm using the ffmpeg extension to my php version.

    <code class="echappe-js">&lt;script type=&quot;text/javascript&quot;&gt;<br />

    You browser doesn't have Flash, Silverlight, Gears, BrowserPlus or HTML5 support.

    well he calls javascript in a php file, in case it will upload the videos.

    what I want is to get the length, resolution, file size and take a screenshot of the video randomly, so far so good, the problem is that it only works with only one upload at a time.
    When sending more than one he does the procedure with ffmpeg, besides the most is not taking a screenshot of the video.
    below is my code
