    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to plot animated time series in R ?

    28 août 2016, par pOrlando

    I am trying use the ’animation’ package in R to plot an animated time series.

    My dataset consists of a time vector and a value vector, each with 1800 rows.

    I keep getting an error message after running the loop which reads :

    Error in jpeg(gname[i]) : unable to start jpeg() device
    
In addition: Warning messages:
    
1: In jpeg(gname[i]) : unable to open file 'g11:30:00.jpg' for writing
    
2: In jpeg(gname[i]) : opening device failed

    Here’s the source code

    timemax<-1800
    
setwd("~/Documents/Animation/")
    
graphdata<-read.csv("filling_line_data_construction_v2.csv")
    
attach(graphdata)
    
gname<-paste("g",time, ".jpg", sep="")
    
for (i in 1:timemax){
    
    jpeg(gname[i])
    
    plot(time[1],value[1],type="l",ylim=c(0,35), xlim=c(0,100),
    
      ylim = c(0, 35),ylab = "", xlab="time")
    
    lines(time[1:i],value[1:i])
    
    dev.off(dev.cur())
    
}

    The end goal is to string together these 1800 plots as a stop animation video by calling the ffmpeg shell :

    shell("C:/ffmpeg/bin/ffmpeg.exe -report -i g%d.jpg -b:v 2048k fillin_lineR.mpg",mustWork=FALSE)

    This is code that I’ve been trying to adapt from http://www.animatedgraphs.co.uk/LondonR.html#slide-30, but this example uses a .tif file instead of .jpg, and my computer gives me 1800 error messages when trying to make a video from .tif files...

    Thanks in advance !

  • mp4 video plays from beginning while seeking to another time [on hold]

    13 août 2013, par user2649860

    i am using lighttpd and h264 with jwplayer. I am trying to stream the MP4 video.

    My problem is that the MP4 video downloads whole file before playing and i have another problem i.e. when i seek to another time/point the video plays from beginning and it plays after the end time also.

    i have already tried the ffmpeg tools to create the h264 video and qt-faststart.exe tool to fix the video index problem of the video. But it does not work.

    Any solution ?? THanks in advanced
