    Préambule
    Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
    Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

  • hevc : Make sure to update the current frame transfer characteristic

    hevc : Make sure to update the current frame transfer characteristic

    Otherwise the first decoded frame will still be tagged with the
    
original transfer instead of the alternative one.

  • Open sourced library on video analysis and key frame extraction

    9 décembre 2015, par sunzhida

    I am new in multimedia analysis area.

    Recently, I am working on a project which is built on AngularJS and Flask framework and I want to realize the following functions in our website :

    • user can cut the video into segments and the website can merge all
      the selected segments into one new video ;
    • the website can extract key frames of the new video which is
      generated by the first step ;
    • the player can get a ’start time’ parameter and a ’end time’ parameter
      (or a ’duration’ parameter) given by user and play the clips based on
      the user input parameters.

    For now, I have searched several tools like JWPlayer, FFMpeg. But I really have no idea on how to use them and whether they are the best tools for these requirements. I was wondering if you might be able to give me some advice.

    Thank you.

  • AIR to ffmpeg via argb frames transfer

    4 mai 2014, par mika

    Hey I’m running into a similar problem as : Converting RGB to YUV, + ffmpeg

    From AIR, I figured the encoding was too long to render frames at a reasonable rate - so I exported the argb ByteArray from bitmap.getPixels(rect) directly to a file.

    So for a 30sec flash animation, I’d export let’s say 1500 frames to 1500 .argb files.

    This method works great. I was able to render HD video using the ffmpeg cmd :

    ffmpeg -f image2 -pix_fmt argb -vcodec rawvideo -s 640x380 -i frame_%d.argb -r 24 -qscale 1.1 -s 640x380 -i ./music.mp3 -shortest render-high.mpg

    So far so good ! However, inbetween the two processes we need to store those 3gb of data.

    I then tried to append all the argb to one single file and have ffmpeg consume it, but didn’t get anything good out of it... Also tried messing tcp/udp but getting stuck...

    Does anyone know of a way to streamline that process and hopefully pipe both Air and ffmpeg together ?
