  • Flutter FFmpeg | Concat Multiple Videos From TXT File And Save As A Video

    7 mai 2023, par Muhammad Hassan

    I have a text file with all path of video files that I want to concat using
https://pub.dev/packages/ffmpeg_kit_flutter in my flutter app.

    


    For this purpose, I write a file my_file.txt with the below data...

    


    /data/user/0/com.example.video_merger/cache/75f72300-1203-4e2c-93cf-65777152f1d16524788775537818173.mp4
/data/user/0/com.example.video_merger/cache/318d5ea7-3e0c-4453-903b-06966aa86f348487775694692938421.mp4


    


    Now I am using the below code to merge all the upper videos.

    


    String outputPath = "/data/user/0/com.example.video_merger/app_flutter/output.mp4";
String commandToExecute = '-f concat -i $rawDocumentPath/my_file.txt -c copy $outputPath';
FFmpegKit.execute(commandToExecute).then((session) async {
  final returnCode = await session.getReturnCode();
  print("FFmpeg Process Exited With ReturnCode = $returnCode");
  GallerySaver.saveVideo(outputPath).then((_) {
    print("Merged Video Saved");
  });
  if (ReturnCode.isSuccess(returnCode)) {
    // SUCCESS
  } else if (ReturnCode.isCancel(returnCode)) {
    // CANCEL
  } else {
    // ERROR
  }
});


    


    But it is giving me error as shown below...

    


    FFmpeg Process Exited With ReturnCode = 1 
E/GallerySaver(31493): /data/user/0/com.example.video_merger/app_flutter/output.mp4: open failed: ENOENT (No such file or directory)


    


    But when I use the below ffmpeg command directly without reading from text file works fine and save my video.

    


    String commandToExecute = '-y -i ${_storedVideoOne!.path} -i ${_storedVideoTwo!.path} -r 24000/1001 -filter_complex \'[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[out]\' -map \'[out]\' $outputPath';


    


    Now my question is that I will have dynamic number of videos to concat so I want to use text file where I will write all paths then will make merged video from them. So what is the error in my ffmpeg command...???

    


    Log Report :

    


    I used the log reporting as follows to get the below output of errors...

    


        FFmpegKit.executeAsync(
      commandToExecute2,
          (session) async {
            final returnCode = await session.getReturnCode();
            print("FFmpeg Process Exited With ReturnCode = $returnCode");
            GallerySaver.saveVideo(outputPath).then((_) async {
              print("Merged Video Saved");
            });
            if (ReturnCode.isSuccess(returnCode)) {
              // SUCCESS
            } else if (ReturnCode.isCancel(returnCode)) {
              // CANCEL
            } else {
              // ERROR
            }
          },
          (log) {
        print("XXXXXXXXXXXX fFmpeg XXXXXXXXXX ${log.getMessage()}");
      },
    );


    


    And here is the Log Output...

  • ffmpeg : cannot copy data stream

    31 mars 2023, par darkshine — , , ,

    I've got the video file captured by DJI drone. The file contains the video stream and two data streams of unknown format. I would like to convert the video from to and also save the both data streams. Unfortunately, I cannot force to copy the data streams from input to the output.

    


    Here is the mp4 file :

    


    ffprobe DJI_0019.MP4

    In the meantime an attempt to save the data streams to separate files succeeds for the both of them with the commands :

    ffmpeg -i DJI_0019.MP4 -map 0:d:1 -c copy -copy_unknown -f data DJI_0019.data1.bin

    


    How to force to copy the data streams from input to output ?

  • FFmpeg - Copy a (not A/V) data stream from input MP4 file [closed]

    31 mars 2023, par darkshine

    I've got an MP4 video file captured by DJI drone. The file contains the video stream (H.264) and also two data streams of unknown format. I would like to convert the video from h.264 to h.265 and also save both of the included data streams. Unfortunately, I cannot force FFmpeg to copy the data streams across from the input file into the output file.

    


    Here is the mp4 file :
