• Anomalie #3619 : [Patch] Sous Windows, SPIP n’affiche pas le n° de version avec Tortoise SVN récent

  21 décembre 2015, par realet RealET

  C’est aussi valable sous Debian 8, c’est subversion 1.8.10-6 qui est installée et le n° de révision SVN est stocké en base SQLite.

  Donc, le patch est aussi utile pour Debian ;-)

• ffmpeg running on windows with java

  24 décembre 2013, par Karn_way

  I have simple test class as

  public static void main(String[] args) throws IOException {
  
  
  
           String[] line = {"ffmpeg -i D:\\hadoop-video\\testVideo\\xyz.mp4 %d.png"};
  
           Runtime.getRuntime().exec(line);
  
  
  
      }

  when I try to run this I am getting

  Exception in thread "main" java.io.IOException: Cannot run program "ffmpeg -i D:/hadoop-video/testVideo/xyz.mp4 %d.png": CreateProcess error=2, The system cannot find the file specified
  
      at java.lang.ProcessBuilder.start(Unknown Source)

      at ImageTest.main(ImageTest.java:13)
  
  Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified

  however file is present on my windows7 machine with location

• video after ffmpeg command conversion is not playing on windows

  10 décembre 2015, par Hemant Kumar

  I am stuck at a very weird and complex problem, hoping if anyone know the solution :

  I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.

  I am using following codec :

  ['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']

  I work on linux and using html5 player on my website. I am converting video in mp4 format.

  Input :

  ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4
  
  </server></server>
