• java.io.IOException : Cannot run program "/data/user/0/com.package.name/files/ffmpeg" : error=13, Permission denied

  12 avril 2020, par KANAYO AUGUSTIN UG

  I am trying to cut a video using FFmpeg library from com.writingminds:FFmpegAndroid:0.3.2...
When I try to run my command

  



  String[] complexCommand = { "-y", "-i", inputFilePath,"-ss", "" + trimStart, "-t", "" + trim, "-c","copy", outputFilePath};
execFFmpegBinary(complexCommand);


  



  I get this error :

  



  


  E/FFmpeg : Exception while trying to run : [Ljava.lang.String ;@c7a48dd

  
 


  java.io.IOException : Cannot run program "/data/user/0/com.package.name/files/ffmpeg" : error=13, Permission denied

  


  



  Even after making sure the library loaded successfully

  



  private void loadFFMpegBinary() {
    try {
        if (ffmpeg == null) {
            ffmpeg = FFmpeg.getInstance(cntxt);
        }
        ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
            @Override
            public void onFailure() {
                Log.i("success", "false");
            }

            @Override
            public void onSuccess() {
                Log.i("success", "true");
            }
        });
    } catch (FFmpegNotSupportedException e) {
    } catch (Exception e) {
    }
}


  



  I have enabled WRITE_PERMISSION in Android.manifest file, and I also tried to write a file to the storage and it worked.

  



  I guess FFmpeg has a default path to write a file which is /data/user/0/com.package.name/files/ffmpeg, but I need to change the default path please anyone with an idea ?

  


• SETX is not recognized as an internal or external command operable program or batch file [duplicate]

  6 avril 2020, par anonymous

  (skip this paragraph if you don't care about context) : So I was trying to record inside of Minecraft using the replay mod, and to render a video I have to install this thing called ffmpeg to render it, and my fears were correct, SETX is not recognized.

  



  So, a while back I had to redo my javac because that wasn't recognized, but when I did get that fixed, it made all my other commands toast, except the basic ones like "copy" or "del". I don't know how, I'd assume I'd need to manually input the path variable and everything because I doubt I could even find anything in the system variables for it, but that may not be the case. Suggest some YouTube vids, or a thorough and non-complicated explanation if you can, because for some reason, some instructions go through one ear and out the other.

  



  I also posted this in /r/feedthebeast, but I doubt anyone will find a solution there.

  



  Thanks.
