• How to batch "touch" files in subfolder with data from parent folder

  12 août 2019, par Constantine Grigorakis

  I have a folder named "Video" on my Desktop and inside that folder are a bunch of .MTS video files. (00000.MTS, 00001.MTS, 00002.MTS etc...)

  There is also a subfolder "H.265" (Video > H.265) which contains files (00000.mp4, 00001.mp4, 00002.mp4 etc...) which were made by converting the files from the parent folder. The problem is they don’t contain the correct date created metadata.

  I want to use the command

  touch -r 00000.MTS 00000.mp4
  
  touch -r 00001.MTS 00001.mp4
  
  ...
  
  touch -r 000mn.MTS 000mn.mp4

  to copy the date from the MTS to the mp4 file.

  Is there a way I could write a for loop or something to do this for every single file ?

  I am using MacOS Mojave.

• 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 ?
