How to convert n numbers of images into a video slideshow with putting some transition on each images with flutter_ffmpeg ?
26 avril 2023, par Shruti Ramnandan SharmaI'm trying to convert images into a video slideshow with some transition. I have used flutter_ffmpeg plugin , with this plugin I have created with only 3 images but I want to add n numbers of images but couldn't able to find solutions for it. I tried to add more images but it throws error.


I'm gonna add some piece of code below :


- 

- Instance of FlutterFFmpeg




final FlutterFFmpeg _flutterFFmpeg = FlutterFFmpeg(); 


- 

- Picking multiple images from the gallery and applying command to convert images into a video




void mergeImageVideo() async {
 final ImagePicker picker = ImagePicker();
 final images = await picker.pickMultiImage();

 var im1 = images[0].path;

 var im2 = images[1].path;

 var im3 = images[2].path;

 //-shortest
 openLoadingDialog(context, "Creating video");
 generateFilePath("ImageVideoMerge").then((outputFile) {
 var backgroundColor = 'FFF44336';

 String ffmpegCommand = VideoUtil.generateImagesToVideoScript(
 im1, im2, im3, outputFile, 'mpeg4', '', backgroundColor);

 print("ffmpegCommand==> $ffmpegCommand");
 _flutterFFmpeg.execute(ffmpegCommand).then((v) {
 if (v == 0) {
 var file = File(outputFile);
 Navigator.pop(context);
 showSnackBar(context, "Images Added Successfully", Colors.black);
 updateVideoPlayer(file);
 } else {
 Navigator.pop(context);
 }
 }).then((executionId) {
 });
 });
 }

Saving an audio blob into the backend or Azure as an mp3 file using ffmpeg
2 juin 2021, par AnneI have an asp.net webforms, and I am using javascript and navigator.mediaDevices.getUserMedia to record an audio message.
This message has to be loaded into Azure once recorded.


So far, I have :
2 buttons, start and stop to record the audio blob


At the end of the process, I am trying to use ffmpeg to record the blob into a folder in my application, I can then load the file into Azure (I have the code ready for this one).
Or ideally, save directly to Azure.


I have installed ffmpeg in my application using nuget packages (I tried Xabe ffmpeg downloader and Accord video ffmpeg), however ffmpeg is not recognised when I run the function SendData() and I get this error :
Uncaught Error : Module name "ffmpeg" has not been loaded yet for context : _. Use require([])


My questions are :


- 

- How can I install ffmpeg in an asp.net wbeform and register it on the page ?
- Is there another way to save an audio blob to Azure ?
- Is it possible to save the audio chunks into a memory stream that I can later upload into Azure ?








Thank you for your help
