    I don't have deeper experience with ffmpeg conversions and codecs. It seems to me that this is a frames related problem. Do you have a clue why does it fail ? What options should I use in ffmpeg command to solve this ? Thanks for any help.

    


  • Flutter (Dart) : Merge two videos and view the new output in the device's gallery (photos)

    17 juin 2020, par Ittai Barkai

    I am aware that there already exists a solution to a very similar question, which can be found on the following link : Flutter/Dart : Find two video segments and merge them into a single valid video file ? However, being relatively new to Flutter (and programming in general) I cannot seem to replicate the desired result.

    



    My app is very simple and currently looks like this :

    



    enter image description here

    



    I click on the button "Record Video" to record two videos, which are both successfully stored into the device's gallery. Using the Flutter image_picker and gallery_saver packages and the following piece of code :

    



        void _recordVideo() async {
    ImagePicker.pickVideo(source: ImageSource.camera)
        .then((File recordedVideo) {
      if (recordedVideo != null && recordedVideo.path != null) {
        setState(() {
          _buttonText = 'Saving in Progress...';
        });
        GallerySaver.saveVideo(recordedVideo.path).then((_) {
          setState(() {
            _buttonText = 'Video Saved!\n\nClick to Record New Video';
            if (_storedVideoOne == null) {
              _storedVideoOne = recordedVideo;
              print('video 1 stored');
            } else {
              _storedVideoTwo = recordedVideo;
              print('video 2 stored');
              _videoMerger();
            }
          });
        });
      }
    });
  }


    



    I can view these videos when I click on the button at the bottom "View Video From Gallery".

    



    Next I try to merge these two stored video files, using the flutter_ffmpeg package, as well as following the solution provided in the stack overflow question mentioned above. I try and do this using the following function I wrote :

    



    void _videoMerger() async {


    final appDir = await syspaths.getApplicationDocumentsDirectory();
    String rawDocumentPath = appDir.path;
    final outputPath = '$rawDocumentPath/output.mp4';

    final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();

        String commandToExecute = '-i ${_storedVideoOne.path} -i ${_storedVideoTwo.path} -filter_complex \'[0:0][1:0]concat=n=2:v=1:a=0[out]\' -map \'[out]\' outputPath';
        _flutterFFmpeg.execute(commandToExecute).then((rc) => print("FFmpeg process exited with rc $rc"));

  }


    



    But after running the function I do not seem to get a new combined video, which should be stored in outputPath and ideally also viewable in the gallery. Uploaded the Flutter project onto GitHub here :

    



    https://github.com/IttaiBarkai/Flutter-Video-Merger

    



    Any help would be greatly appreciated :)
