  • Contribute to translation

    13 avril 2011

    You can help us to improve the language used in the software interface to make MediaSPIP more accessible and user-friendly. You can also translate the interface into any language that allows it to spread to new linguistic communities.
    To do this, we use the translation interface of SPIP where the all the language modules of MediaSPIP are available. Just subscribe to the mailing list and request further informantion on translation.
    MediaSPIP is currently available in French and English (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • make error in OpenCV installation on ubuntu (ffmpeg CODEC_ID_XXXX was not declared in scope)

    22 avril 2015, par Anurag Priyadarshi

    I am trying to install OpenCV following this tutorial. I am through cmake.(The configuration is given at the end.) However make shows error :make[2]: ***[modules/highgui/CMakeFiles/opencv_highgui.dir/src/cap_ffmpeg.cpp.o] Error 1
    One link pointed out reason as different version of opencv and ffmpeg, but I found a piece of code in cap_ffmpeg_impl.hpp that appears to be handling it.

    #if LIBAVCODEC_BUILD >= CALC_FFMPEG_VERSION(54,25,0)
    
#  define CV_CODEC_ID AVCodecID
    
#  define CV_CODEC(name) AV_##name
    
#else
    
#  define CV_CODEC_ID CodecID
    
#  define CV_CODEC(name) name
    
#endif

    Not sure if it is ok for this to be commented.

    Also, I could try installing ffmpeg seperately, but I am not sure how dependencies are handled in this installation around libav.

    Would be thankful for any help in solving this problem, as well as tips/links for OpenCV installation in general.

  • Knitr Plot Animation - disappearing output files ?

    20 avril 2015, par tcs

    I downloaded the latest ffmpeg (exe version), unzipped the files, renamed the directory to ffmpeg, copied the directory into c :\Program Files. I appended my PATH variable to include c :\Program Files\ffmpeg\bin. Finally, I restarted Rstudio.

    While attempting to run the following code chunk :

    ```{r perf_plot, fig.width=7, fig.height=6, fig.show='animate'}
    
library(corrplot)
    
corrplot(m, method = "circle")
    
m&lt;-sequence_2_matrix(perf_list[[1]])
    
corrplot(m)
    
for (i in 2:length(perf_list)) {
    
  m&lt;-(m*(i-1)+sequence_2_matrix(perf_list[[i]]))/i
    
  corrplot(m,method = "circle")
    

    
}

    I see within the output in in my RMarkdown window that the ffmpeg call seems to be successfully run, but while watching the directory where my code is located the png that is attempted to be created can often disappear, or not appear at all. Strangeness.

    Any ideas on what might be happening ? I’ve tried adding in other graphs, and I see this random behavior of the file folder appearing disappearing, sometimes the file is created, other times not.
