• ffmpeg returns "method SETUP failed : 404 Not Found"

  1er juillet 2019, par Alex

  We’re using ffmpeg (build ffmpeg-20190628-098ab93-win32-static) to take a snapshot from camera RTSP streams on a Win 10 system. On some cameras, we’re getting this error :

  [rtsp @ 06813ac0] method SETUP failed: 404 Not Found
  
  rtsp://username:password@example.com: Server returned 404 Not Found

  Here’s an example command we use :

  ffmpeg -y -i rtsp://username:password@example.com -vframes 1 -pix_fmt yuvj420p 
  
    -vf select='eq(pict_type\,I)' -q:v 1 _test.jpg

  However, VLC can load the same stream (we can’t use VLC, though) from the same machine. Additionally, we’ve opened the firewall to ffmpeg (it popped up the two firewall dialogs and we allowed it through).

  We’ve found posts on the DESCRIBE error but nothing on SETUP. Any help is appreciated. Thank you.

  Update : In VLC, that RTSP stream asks for credentials twice for some reason. Wondering if that’s the cause.

• 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 "Non-monotonous DTS in output stream 0:1" when trying to convert a m3u8 file into a mp4 using ffmpeg

  23 mars 2019, par Alessandro Autiero

  I’m currently coding a desktop util that downloads Twich Clips if they meet some requirements. As the twitch api gives as a response a m3u8 file, I have to convert it into a mp4. To do with I’m executing a cmd command through my Java application using the ProcessBuilder API built into Java. The command works fine, but sometimes I get a buggy video that has broken frames and audio. Here’s my code :

  public static void convertFile(File input, File output) {
  
      String command = "ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -vsync 2 -i \"" + input.getAbsolutePath() + "\" -c copy " + "\"" + output.getAbsolutePath() + "\"";
  
      System.out.println("______________________________________________________");
  
      System.out.println("Converting file...");
  
      System.out.println("Using as input " + input.getAbsolutePath());
  
      System.out.println("Using as output " + output.getAbsolutePath());
  
      System.out.println("Using as command: " + command);
  
      System.out.println("______________________________________________________");
  
      setHasDone(false);
  
  
  
      ProcessBuilder pb = new ProcessBuilder();
  
      pb.command(command.split(" "));
  
  
  
      pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
  
      pb.redirectError(ProcessBuilder.Redirect.INHERIT);
  
  
  
      Process process;
  
      try {
  
          process = pb.start();
  
      }catch (IOException e){
  
          e.printStackTrace();
  
          return;
  
      }
  
  
  
      while (process.isAlive()){
  
          setHasDone(false);
  
      }
  
  
  
      setHasDone(true);
  
  }

  Example of broken video :

  When uploaded to youtube lot’s of the video bugs are not present, not really know why, but at the end you can clearly see what I’m talking about. Am I using ffmepg wrong ?

  I posted this as none of the 1000 answers on similar posts helped me.
