    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".

    flvdec : Stop searching for streams once a audio & a video stream has been found

  • Multiple video sources combined into one

    28 septembre 2011, par Oded

    I am looking for an efficient way to do the following :

    Using several source videos (of approximately the same length), I need to generate an output video that is composed of all of the original sources each running in its own area (like a bunch of PIPs in several different sizes). So, the end result is that all the original are running side-by-side, each in its own area/box.

    The source and output need to be flv and the platform I am using is Windows (dev on Windows 7 64bit, deployment to Windows server 2008).

    I have looked at avisynth but unfortunately it can't handle flv and non of the plugins and flv splitters I have tried worked.

    My current process uses ffmpeg in the following manner :

    1. Use ffmpeg to generate 25 png's per second per video, resizing the original as needed.
    2. Use the System.Drawing namespace to combine each set of frames into a new image, starting with a static background, then loading each frame into an Image and drawing to the background Graphics object - this gives me the combined frames.
    3. Use ffmpeg to combine the generated images to a video.

    All this is very IO intensive (which is my processing bottleneck at the moment) and I feel there must be a more efficient way to reach my goal. I do not have much experience with video processing, and don't know what options are out there.

    Can anyone suggest a more efficient way of processing these ?

  • How to write a video encoder with ffmpeg ?

    27 décembre 2013, par SunnyShah

    I want to write an encoder with ffmpeg which can put iFrames (keyframes) at positions I want. Where can I found tutorials or reference material for it ?

    P.S
    Is it possible to do this with mencoder or any opensource encoder. I want to encode H263 file. I am writing under & for linux.
