    This page lists some websites based on MediaSPIP.

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • lavfi/overlay : show incoming frames on debug messages

    lavfi/overlay : show incoming frames on debug messages

    This is especially useful to debug queue overflow issues.
    

    Ideally we should be able to set the debug message at the
    
dualinput/framesync level, but they do not have the information related
    
to the filter context and the inlink, so cannot access much useful
    
information.

  • exec() with SuPHP and SafeMode Off (php.ini local) show wrong path and fail execution

    29 juillet 2013, par abkrim

    Try this

    &lt;?php
    
     if (exec(&#39;/usr/bin/ffmpeg -i 47.mp4 -acodec aac -ab 128kb -vcodec mpeg4 -b 1220kb -mbd 1 -s 320x180 final_video.mov"&#39;))
    
         { echo "Success"; }
    
     else { echo "No good"; }
    
?>

    But on shell see—>

    sh: /usr/local/php/bin/ffmpeg: No such file or directory

    Server it's Apache+SuPHP with a local php.ini file for disable SafeMode

    I don't understand why show sh : /usr/local/php/bin/ffmpeg : No such file or directory instead real path put on php script.

  • How to use fig.show=animate in knitr without administrator privileges

    23 mai 2013, par Stéphane Laurent

    I use Windows without administrator privileges hence I cannot set a path in the Windows PATH variable.

    The ffmpeg.exe file is in my "U:/ProgramFiles/ImageMagick-6.8.5-5/" folder.

    I have found how to use the saveVideo() function of the animate package :

    ani.options(ffmpeg = shQuote(&#39;U:/ProgramFiles/ImageMagick-6.8.5-5/ffmpeg.exe&#39;))
    
saveVideo({
    
  par(mar = rep(3, 4))
    
  for (i in seq(pi/2, -4/3 * pi, length = 12)) {
    
    plot(0, 0, pch = 20, ann = FALSE, axes = FALSE)
    
    arrows(0, 0, cos(i), sin(i))
    
    axis(1, 0, "VI"); axis(2, 0, "IX")
    
    axis(3, 0, "XII"); axis(4, 0, "III"); box()
    
  }
    
},
    
        video.name="mavideo.mp4",
    
        outdir="U:/Data/Rtests/Animation")

    But I haven't find how to knit a Rmd file with the option fig.show=animate in a chunk, for instance :

    ```{r clock, fig.width=7, fig.height=6, fig.show=&#39;animate&#39;}
    
par(mar = rep(3, 4))
    
for (i in seq(pi/2, -4/3 * pi, length = 12)) {
    
    plot(0, 0, pch = 20, ann = FALSE, axes = FALSE)
    
    arrows(0, 0, cos(i), sin(i))
    
    axis(1, 0, "VI"); axis(2, 0, "IX")
    
    axis(3, 0, "XII"); axis(4, 0, "III"); box()
    
}
    
```

    I have tried to modifiy the hook_ffmpeg_html() function by only changing the ffmpeg.cmd variable :

    ```{r}
    
 hook_ffmpeg_html2 &lt;- function (x, options) 
    
{ 
    
    ........ 
    
    ffmpeg.cmd = paste("-y", "-r", 1/options$interval, 
    
        "-i", fig.fname, mov.fname) 
    
    ffmpeg.cmd &lt;-  paste(&#39;"U:/ProgramFiles/ImageMagick-6.8.5-5/ffmpeg"&#39;, ffmpeg.cmd) 
    
   ...... 
    
} 
    
opts_knit$set(animation.fun = hook_ffmpeg_html2) 
    
```

    But this chunk does not work, below is the error message :

    label: unnamed-chunk-1 
    
Warning in block_exec(params) : 
    
  failed to tidy R code in chunk  
    
reason: Error in base::parse(text = text, srcfile = NULL) : 
    
  21:14: unexpected symbol
