• FFmpeg giving a wierd "Permission denied" error (Digitalocean VPS Ubuntu 18.04)

  10 mai 2021, par DJ Danny

  I've set up a VPS server on Digitalocean. Installed Ubuntu 18.04, LAMP, etc.
Finally, I installed ffmpeg. It is working fine from terminal but when I try to execute it through php it gives a weird "Permission denied" error :

  


  Here is some information :

  
root@vl :/# whereis ffmpeg
  
ffmpeg : /usr/local/bin/ffmpeg
  
root@vl :/# whereis ffprobe
  
ffprobe : /usr/local/bin/ffprobe
  

  


  root@vl :/# ffmpeg -version

From the past 24 hours I've tried installing ffmpeg in different ways (compiling & apt install), I've also tried changing the permission but still I'm stuck with this error.
  
Any help would be highly appreciated !
  
Thanks

  


• Getting error "WebAssembly.Memory() : could not allocate memory" when running ffmpeg.wasm on android chrome browser

  Code for ffmpeg :

  


  const downloadWithFFMPEG = async () =>{
  const sourceBuffer = await fetch(recordingURL).then(r => r.arrayBuffer());
  await ffmpeg.load();
  await ffmpeg.FS(
    "writeFile",
    "input.webm",
    new Uint8Array(sourceBuffer, 0, sourceBuffer.byteLength)
  );
  await ffmpeg.run("-i", "input.webm", "-c", "copy", "output.mp4")
  const output = ffmpeg.FS("readFile", "output.mp4");
  var link = document.createElement('a')
  link.href = URL.createObjectURL(new Blob([output.buffer], { type: 'video/mp4;codecs=H264' }));
  link.download = this.data;
  link.click();
  recording = false;
}


  


  Brief about problem :
The error only comes for android chrome browser. The same code works fine on pc/laptop chrome.
Have also enabled Webassembly-thread on chrome ://flags for android browser as someone suggested me to do it but still same error. Can someone help me ?

  


• Cannot run program "/data/user/0/com.athkar.musliem/files/ffmpeg" : error=2, No such file or directory

  3 avril 2021, par gejivi2011

  I am trying to make a video with an audio and single image, but have the error that on the title, I am using android studio with FFmpeg :
I need to make that video with just one image and one mp3 file

  


  The error was :

  


  Exception while trying to run: [Ljava.lang.String;@b6e12b4
java.io.IOException: Cannot run program "/data/user/0/com.athkar.musliem/files/ffmpeg": 
error=2, No such file or directory

Caused by: java.io.IOException: error=2, No such file or directory


  


  1- this code to get the save directory

  


      String root = Environment.getExternalStorageDirectory().toString();
    myDir = new File(root);


  


  2- The image uri :

  


   imageUri = Uri.parse("android.resource://com.athkar.musliem/drawable/" + R.drawable.test_image);


  


  3- to select mp3 file :

  


      public void openMp3Selector() {
    Intent intent;
    intent = new Intent();
    intent.setAction(Intent.ACTION_GET_CONTENT);
    intent.setType("audio/*");
    startActivityForResult(Intent.createChooser(intent, "Select mp3"), REQ_CODE_PICK_SOUNDFILE);
}

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQ_CODE_PICK_SOUNDFILE && resultCode == Activity.RESULT_OK) {
        if ((data != null) && (data.getData() != null)) {
            audioFileUri = data.getData();
        }
    }
}


  


  4- finally FFmpeg code :

  


    fFmpeg = FFmpeg.getInstance(VideoMakerActivity.this);
            String[] strArr = new String[]{"-y", "-r", imageUri.getPath(), "-i", imageUri.getPath(), "-vcodec", "libx264", "-r", "2", "-pix_fmt", "yuv420p", "-preset", "ultrafast", audioFileUri.getPath()};
            try {
                fFmpeg.execute(strArr, new ExecuteBinaryResponseHandler() {
                    @Override
                    public void onSuccess(String message) {
                        super.onSuccess(message);
                        Log.e("MAS", "onSuccess");
                    }

                    @Override
                    public void onProgress(String message) {
                        super.onProgress(message);
                        Log.e("MAS", "onProgress");

                    }

                    @Override
                    public void onFailure(String message) {
                        super.onFailure(message);
                        Log.e("MAS", "onFailure");

                    }

                    @Override
                    public void onStart() {
                        super.onStart();
                        Log.e("MAS", "onStart");

                    }

                    @Override
                    public void onFinish() {
                        super.onFinish();
                        Log.e("MAS", "onFinish");

                    }
                });
            } catch (FFmpegCommandAlreadyRunningException e) {
                e.printStackTrace();
            }
