Is there a way to horizontal flip video captured from flutter front camera
5 mai 2024, par JoyJoyBasically, I'm trying to flip video horizontally after capturing it from flutter front camera. So I start recording, stop recording, flip the video and pass it to another page. I'm fairly new and would appreciate any assistance as my code isn't working


I've tried doing so using the new ffmpeg_kit flutter


Future<void> flipVideo(String inputPath, String outputPath) async{
final ffmpegCommand = "-i $inputPath -vf hflip $outputPath";
final session = FFmpegKit.executeAsync(ffmpegCommand);
await session.then((session) async {
 final returnCode = await session.getReturnCode();
 if (ReturnCode.isSuccess(returnCode)) {
 print('Video flipping successful');
 } else {
 print('Video flipping failed: ${session.getAllLogs()}');
 }
});}

void stopVideoRecording() async {
XFile videopath = await cameraController.stopVideoRecording();

try {
 final Directory appDocDir = await 
 getApplicationDocumentsDirectory();
 final String outputDirectory = appDocDir.path;
 final String timeStamp = DateTime.now().millisecondsSinceEpoch.toString();
 final String outputPath = '$outputDirectory/flipped_video_$timeStamp.mp4';

 await flipVideo(videopath.path, outputPath);

 // Once completed,
 Navigator.push(
 context,
 MaterialPageRoute(
 builder: (builder) => VideoViewPage(
 path: File(outputPath),
 fromFrontCamera: iscamerafront,
 flash: flash,
 )));
 print('Video flipping completed');
} catch (e) {
 print('Error flipping video: $e');
}
</void>

In Flutter, how to get image pixel
12 janvier 2024, par Pianonemy code here


var response = await Dio().get(
 url,
 options: Options(responseType: ResponseType.bytes)
);
Uint8List? srcImage = Uint8List.fromList(response.data);
Uint8List? watermark = await captureWaterMark();
Image i = Image.memory(srcImage!);
//how can I get the pixel (Image i) such like 1920*1080 or just width/hight pixel
...tell me how to do...
srcImage = await addWaterMarkByFfmpegCommand(srcImage, watermark);
 final result = await ImageGallerySaver.saveImage(
 srcImage!, name: name,
 );


i need get the pic pixel so that i can use it in ffmpeg command, it a func that add a watermark into srcImage, but cause their pixel ratio too diff to adapted watermark


i try to get pixel from ffmpeg... but i failed


/// addWaterMark by using ffmpeg Command
Future addWaterMarkByFfmpegCommand(Uint8List srcImg, Uint8List watermark) async {
 try {
 final Directory tempDir = await Directory.systemTemp.createTemp();
 final File image1File = File('${tempDir.path}/srcImg.jpg');
 await image1File.writeAsBytes(srcImg);
 final File image2File = File('${tempDir.path}/watermark.png');
 await image2File.writeAsBytes(watermark);

 final String outputFilePath = '${tempDir.path}/output.jpg';
 //when i get srcImage pixel, the positions in bold(iw*1) in the following commands will be replaced to make watermark adapted
 final String command =
 '-i ${image1File.path} -i ${image2File.path} -filter_complex "[1:v]scale=**iw*1**:-1[v1];[0:v][v1]overlay=10:10" -frames:v 1 $outputFilePath';
 await FFmpegKit.execute(command);

 final File outputFile = File(outputFilePath);
 final Uint8List outputBytes = await outputFile.readAsBytes();
 return outputBytes;
 } catch (e) {
 print('Error executing ffmpeg command: $e');
 }
 return null;
}


ps : i am new to flutter and ffmpeg, plz help me, I'd appreciate, thanks alot

The new GDPR data protection regulation and potential consequences on Piwik
GDPR is a new data protection related regulation in Europe. GDPR stands for General Data Protection Regulation.
The purpose of this European regulation is to strengthen and unify data protection for all individuals within the European Union. This also includes entities outside Europe willing to do business with European citizens. GDPR is a set of processes you need to follow within your organization to protect the privacy of European citizens.
GDPR will start to apply in May 2018. It is recognized to be dissuasive because of the potential penalty of up to 4% of the yearly turnover, in case of infringement.
Many articles have been written about GDPR including our previous article. Few of them are explaining how it will affect web analytics vendors : this is what this article is about.
Am I really impacted by GDPR if I am a Piwik user ?
As Piwik can collect personal data, the answer is yes. Piwik analytics data is impacted by the GDPR.
As GDPR is a general concept, we decided from the official guidelines to assume what will be the potential consequences on the use of Piwik.
There are 2 potential scenarios we can identify :
- 1 – You are collecting personal data with Piwik
- 2 – You are not collecting personal data with Piwik
1 – Personal data collection with Piwik
According to GDPR : IP addresses, cookies, UserID are personal data.
IP addresses are personal data, so you will have to anonymize them unless you receive explicit consent from the visitor. Please view the following article in order to learn : how can I anonymize IP addresses in Piwik ?
According to GDPR, cookies are personal data too. But as all cookies are not created equal it may be possible that some need to require user consent whereas other not. Whatever will be the final decision, you can learn about the first-party cookies created by Piwik and how to disable all tracking cookies in Piwik ?
User ID, you are impacted if the User ID you assign is specific to an individual or if you can cross the User ID data further and find back the individual personal data.
Any extra personal data you may collect with Piwik, it could be for example : first names, family names, e-mail address… You are able to collect such data using custom dimensions, custom variables…
What are the rules I have to comply with ?
By collecting personal data, you will have to respect EU citizens rights, which include :
- The possibility for them to view the data you collected on them
- The possibility to rectify some data concerning them
- The possibility to delete their data when they request about it
As you can imagine, for the first obligation, you will have to export all the data. So if a user is requesting it, you will have to export the data linked to his IP address(es). It can be easily exported as a .csv file for example.
In order to do that, just create a segment according to the IP address of the user who requested it and then export the “Visitor log” report.
If the personal data is not linked with the IP address but other attributes such as User ID or a custom dimension, you can provide the same data export by using the segment function and filtering on the personal data field.The data edit and deletion process on Piwik is a bit trickier as it currently requires administration system skills. We are planning to develop a new plugin for GDPR compliance (which will be available for free on the Marketplace). This plugin will let you edit and easily delete data of a particular user. Currently you can delete a specific user’s data by accessing the Piwik database and directly delete the different records for this specific user.
2 – You are not collecting personal data with Piwik
Unfortunately it is not because you do not collect personal data that you will not be affected by GDPR.
The details of GDPR are not confirmed yet and GDPR could involve enabling the DoNotTrack setting by default on all browsers.
Yes, you read it well, by default, unless the internet user uncheck this option, Piwik respecting DoNoTrack would not be able to track any user. If one needed to collect data anyway, Piwik Log Analytics and server-side tracking can be considered.If you need help regarding how to set up your Piwik installation in order to be GDPR compliant :
