  • How to create video from multiple gallery images store in array flutter ffmpeg

    26 janvier 2023, par Ammara

    I select images from gallery using multi_image_picker in flutter and store all images in array.

    


      try {
   resultList = await 
   MultiImagePicker.pickImages(
    maxImages: 300,
    enableCamera: true,
    selectedAssets: images,
    materialOptions: MaterialOptions(
      actionBarTitle: "Photo Editor and Video 
   Maker App",
    ),
  );
 }


    


    User can select images from gallery and store in resultlist array.
Now I want to pass this array to ffmpeg to create video from all these images.

    


    I try a lot and search almost all sites but fail. Here is my code.

    


    Future<void> ConvertImageToVideo () async{&#xA;const String BASE_PATH = &#x27;/storage/emulated/0/Download/&#x27;;&#xA;const String AUDIO_PATH = BASE_PATH &#x2B; &#x27;audiio.mp3&#x27;;&#xA;const String IMAGE_PATH = BASE_PATH &#x2B; &#x27;image002.png&#x27;;&#xA;const String OUTPUT_PATH = BASE_PATH &#x2B; &#x27;output02.mp4&#x27;;&#xA;// final FlutterFFmpeg _flutterFFmpeg = FlutterFFmpeg();&#xA;if(await Permission.storage.request().isGranted){&#xA;  List<asset> resultlist  = <asset>[];&#xA;  String commandToExecute =&#xA;      &#x27;-r 15 -f mp3 -i ${AUDIO_PATH} -f image2 -i ${resultlist} -y ${OUTPUT_PATH}&#x27;;&#xA;  await FFmpegKit.execute(commandToExecute).then((session) async {&#xA;    final returnCode = await session.getReturnCode();&#xA;    final state = await session.getState();&#xA;    if (ReturnCode.isSuccess(returnCode)) {&#xA;      print("ruuning   "&#x2B;state.toString());&#xA;      print("video created " &#x2B; returnCode.toString());&#xA;    } else if (ReturnCode.isCancel(returnCode)) {&#xA;      print("video cancel "  &#x2B; returnCode.toString());&#xA;    } else {&#xA;      print("error " );&#xA;    }&#xA;  });&#xA;}else if (await Permission.storage.isPermanentlyDenied) {&#xA;  openAppSettings();&#xA;}&#xA;</asset></asset></void>

  • FFMPEG sidechaincompress not working as it should ?

    23 octobre 2017, par Taapo

    I have been trying to get sidechaining to work with FFMPEG, but my complex filter skills are lacking.

    I’m running two aif files into ffmpeg, hoping the voice would "duck" the background music when the voice-over is speaking. But I get an error with this command-line (on Windows, with latest FFMPEG binary) :

    ffmpeg.exe -i temp_music.aif -i temp_voice.aif \
    
-filter_complex "[1:a]asplit=2[sc][mix];[0:a] \
    
[sc]sidechaincompress=threshold=0.1:ratio=5[bg]; \
    
[bg][mix]amerge[fin‌​al]" -map [final] final.mp3

    Everything decodes fine :

Output with label 'final' does not exist in any defined filter graph, or was already used elsewhere.

    But then I receive an error :

    Output with label ’final’ does not exist in any defined filter graph,
    or was already used elsewhere.

    Anybody knows why ?
