• java.io.IOException : Cannot run program "usr/bin/ffmpeg " : error=2, No such file or directory

  8 juin 2021, par Madan Madan

  I am experiencing errors when executing ffmpeg command from java program in Ubuntu server. When I execute in putty it executes successfully but from java it gives me the exceptions of

  



  java.io.IOException: Cannot run program "/usr/bin/ffmpeg ": 
error=2, No such file or directory


  



  My Code below :

  



  public String convert3gpTomp4(File contentFile, String filename) {
    String[] cmd = new String[6];
    filename = StringUtils.substringBefore(filename, ".");      
    cmd[0] =  "/usr/bin/ffmpeg ";
    cmd[1] = "-y ";
    cmd[2] = "-i ";
    cmd[3] = contentFile.getPath();
    cmd[4] = "  -acodec copy ";
    String myfilename = filename +"eg.mp4";
    cmd[5] = contentFile.getParent() + "/" + myfilename;        

    if (execute(cmd)){
            return myfilename;
    }else{      
        return null;
    }

   }
}

public boolean execute(String[] cmd){
    try{
        Runtime rt= Runtime.getRuntime();

        Process proc = rt.exec(cmd);

        StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR");
        StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT");
        errorGobbler.start();
        outputGobbler.start();

        int exitVal = proc.waitFor();
        String sb = outputGobbler.sb.toString();
        String eb = errorGobbler.sb.toString();

        System.out.println("Command Exceute Exit value: " + exitVal);

        proc.destroy();

        return true;
    }
    catch(java.io.IOException e ){System.out.println("IOException "+e);e.printStackTrace();}
    catch(java.lang.InterruptedException e){}

    return false;

}


  



  Output of ffmpeg command :

  



  /usr/bin/ffmpeg -y -i /mydata/clip1.3gp -acodec copy /mydata/clip1eg.mp4


  



  When I run above command in putty , it executes successfully but from Java program.

  



  In the program, I also tried with the following but no success.

  



  usr/bin/ffmpeg
/bin/ffmpeg
ffmpeg
/root/usr/bin/ffmpeg


  



  Please let me know where I am doing wrong.

  



  Thanks,

  


• How to fix "moov atom not found" error in ffmpeg ?

  20 avril, par user10664722

  Well, I'm using this project to create a Telegram bot which receives URL of .mp4 files, downloads them on server and uploads them to Telegram.

  


  Issue

  


  Everything works fine so far, except converting certain .mp4 files.

  


  For example if I use a sample .mp4 video from https://sample-videos.com/. Then it works fine and converts it successfully.

  


  But if I use a video from some random website which is also simple .mp4 file, it doesn't work and throws this error :

  


  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x1932420] Format mov,mp4,m4a,3gp,3g2,mj2 detected only with low score of 1, misdetection possible !
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x1932420] moov atom not found

• How to fix "fatal error : x.264 no such file or directory"

  24 avril 2019, par user11340790

  I wrote a makefile which builds a C program attaching the x.264 header. After trying to execute the makefile in terminal I receive the fatal error :
  "example.c line [line of #include ] x264.h no such file or directory". Below you can find the C code and makefile (located in the same folder, the library - containing the x264.pc file- is in the folder libx264 of the parent folder). I would be very grateful if you could help with the linkage.

  Makefile :

      CC = gcc
  
  
  
      CFLAGS = -c -Wall `export PKG_CONFIG_PATH=../libx264 && pkg-config            --cflags x264`
  
      LDFLAGS = -static `export PKG_CONFIG_PATH=../libx264 && pkg-config --libs --static libx264`
  
  
  
  
  
      all: Release
  
  
  
      Debug: CFLAGS += -g
  
      Debug: example
  
  
  
      Release: example
  
  
  
      test: example.o
  
          $(CC) -o example example.o $(LDFLAGS)
  
  
  
      test.o: example.c
  
          $(CC) $(CFLAGS) example.c -o example.o
  
  
  
      clean:
  
          rm -f example.o example

  example.c code

      #include 
  
      #include 
  
      int main( int argc, char **argv )
  
      {
  
          int width, height;
  
           return 0;
