• Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux

  15 février 2020, par miguelmorin

  I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

  I call this command to concatenate the files :

  ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4

  where files_to_combine is :

  file ./short_DSC_0013.MOV
  
  file ./short_DSC_0014.MOV
  
  file ./short_DSC_0015.MOV
  
  file ./short_DSC_0016.MOV
  
  file ./short_DSC_0017.MOV
  
  file ./short_DSC_0018.MOV
  
  file ./short_DSC_0019.MOV

  I call this command from the directory containing the video files and files_to_combine.

  On Windows with a nightly build, I get the error :

  files_to_combine : Invalid data found when processing input
  

  I changed file ./DSC_0013.MOV to these options, all with the same error :

  file 'short_DSC_0013.MOV'
  
  file '.\short_DSC_0013.MOV'
  
  file 'F:\short_DSC_0013.MOV'

  How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

  Update with log-level 48

  I ran the same command with -v 48 and got :

  F :\brain squids>C :\Users\migue\Desktop\ffmpeg-20200211-f15007a-win64-static\bin\ffmpeg.exe -v 48 -i files_to_combine -vcodec libx264 show.mp4

  Update because of wrong command

  I had mistyped the command. The right command has a -f in front of concat, which I found because the accepted answer was able to make the command work in a similar environment :

  ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4

• 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 ?
