• ffmpeg concat two videos with different sizes encounter "do not match" error

  1er juillet 2019, par baojieqh

  I’m trying to concat 4 mp4 files. I’m using the command below but not able to concat

  ffmpeg -i L00.mp4 -i L01.mp4 \
  
    -filter_complex "[0:v] [0:a] [1:v] [1:a] concat=n=2:v=1:a=1 [v] [a]" \
  
    -map "[v]" -map "[a]" output.mp4

  Getting this error :

  Input link in1:v0 parameters (size 1150x722, SAR 1:1) do not match the corresponding output link in0:v0 parameters (1158x690, SAR 1:1)

  This command from this post

  ffmpeg -i L00.mp4 -i L01.mp4 -filter_complex \
  
  "[0:v]scale=1158:722:force_original_aspect_ratio=decrease,pad=1158:722:(ow-iw)/2:(oh-ih)/2[v0]; \
  
   [1:v]scale=1158:722:force_original_aspect_ratio=decrease,pad=1158:722:(ow-iw)/2:(oh-ih)/2[v1]; \
  
   [v0][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" \
  
  -map "[v]" -map "[a]" -c:v libx264 -c:a aac -movflags +faststart output.mp4

  getting this error :

  Filter pad has an unconnected output

  the dimensions of L00.mp4 is 1158 × 690, L01.mp4 is 1150 × 722.

  how to fix this ?

• 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 !
