Concat filter : Error initializing output stream
18 juin 2020, par Ittai BarkaiThis is a follow-up question to : Flutter (Dart) : Merge two videos and view the new output in the device’s gallery (photos)



In essence, I am trying to record two videos, merge them and then view the new video in the gallery. I am currently having some issues with the flutter_ffmpeg package.



I uploaded the my Flutter project onto GitHub here :



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



Below is a snippet of my code used to execute ffmpeg :



void _videoMerger() async {

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

 final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();

 String commandToExecute = '-y -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"));

 }



and this is the output displayed on my debug console when ffmpeg gets executed :

Flutter (Dart) : Merge two videos and view the new output in the device's gallery (photos)
17 juin 2020, par Ittai BarkaiI 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 :






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 :)



Updated :



Below is the output displayed on my debug console when ffmpeg gets executed :

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.
