  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • FFmpegKitFlutter, Error : MissingPluginException(No implementation found for method ffmpegSession on channel flutter.arthenica.com/ffmpeg_kit)

    12 février, par 7Solomon

    I Have this simple Flutter function, to compress Audio Files

    


    import &#x27;package:ffmpeg_kit_flutter/ffmpeg_kit.dart&#x27;;&#xA;import &#x27;package:ffmpeg_kit_flutter/return_code.dart&#x27;;&#xA;&#xA;&#xA;Future<string> compressAudio(String inputPath) async {&#xA;    try {&#xA;      //     ...&#xA;      final command = &#x27;-y -i "$inputPath" &#x27; // Input file&#xA;          &#x27;-af "loudnorm=I=-16:TP=-1.5:LRA=11,&#x27; // Loudness normalization&#xA;          &#x27;acompressor=threshold=${_config[&#x27;threshold_db&#x27;]}:&#x27;&#xA;          &#x27;ratio=${_config[&#x27;ratio&#x27;]}:&#x27;&#xA;          &#x27;attack=${_config[&#x27;attack&#x27;]}:&#x27;&#xA;          &#x27;release=${_config[&#x27;release&#x27;]},&#x27;&#xA;          &#x27;highpass=f=20,lowpass=f=20000" &#x27; // Audio filters&#xA;          &#x27;-ar 44100 &#x27; // Sample rate&#xA;          &#x27;-b:a 128k &#x27; // Bitrate&#xA;          &#x27;-codec:a libmp3lame &#x27; // MP3 encoder&#xA;          &#x27;-q:a 2 &#x27; // Quality setting for LAME (0-9, lower is better)&#xA;          &#x27;-map_metadata 0 &#x27; // Copy metadata&#xA;          &#x27;"$outputPath"&#x27;; // Output file&#xA;&#xA;      // Execute FFmpeg command&#xA;      final session = await FFmpegKit.execute(command);&#xA;      final returnCode = await session.getReturnCode();&#xA;      final logs = await session.getLogs();&#xA;      print(&#x27;FFmpeg logs: $logs&#x27;);&#xA;&#xA;      if (ReturnCode.isSuccess(returnCode)) {&#xA;        return outputFileName;&#xA;      } else {&#xA;        final logs = await session.getLogs();&#xA;        throw Exception(&#xA;            &#x27;FFmpeg process failed with code $returnCode\nLogs: $logs&#x27;);&#xA;      }&#xA;    } catch (e, stackTrace) {&#xA;      print(&#x27;Error: $e&#x27;);&#xA;      print(&#x27;Stack trace: $stackTrace&#x27;);&#xA;      throw Exception(&#x27;Failed to compress audio: $e\nStack trace: $stackTrace&#x27;);&#xA;    }&#xA;  }&#xA;</string>

    &#xA;

    And I get this error&#xA;Error: MissingPluginException(No implementation found for method ffmpegSession on channel flutter.arthenica.com/ffmpeg_kit)

    &#xA;

    This is the Stacktrace

    &#xA;

    flutter: Error: MissingPluginException(No implementation found for method ffmpegSession on channel flutter.arthenica.com/ffmpeg_kit)&#xA;flutter: Stack trace: #0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:332:7)&#xA;<asynchronous suspension="suspension">&#xA;#1      AbstractSession.createFFmpegSession (package:ffmpeg_kit_flutter/abstract_session.dart:71:11)&#xA;<asynchronous suspension="suspension">&#xA;#2      FFmpegSession.create (package:ffmpeg_kit_flutter/ffmpeg_session.dart:40:21)&#xA;<asynchronous suspension="suspension">&#xA;#3      FFmpegKit.executeWithArguments (package:ffmpeg_kit_flutter/ffmpeg_kit.dart:44:9)&#xA;<asynchronous suspension="suspension">&#xA;#4      FileProcessor.compressAudio (package:predigt_upload_fl/file.dart:182:23)&#xA;<asynchronous suspension="suspension">&#xA;#5      _DetailPageState._handleSubmit (package:predigt_upload_fl/GUIs/LiveStreamDetailPage.dart:334:30)&#xA;<asynchronous suspension="suspension">&#xA;&#xA;&#xA;══╡ EXCEPTION CAUGHT BY SERVICES LIBRARY ╞══════════════════════════════════════════════════════════&#xA;flutter.arthenica.com/ffmpeg_kit_event)&#xA;&#xA;When the exception was thrown, this was the stack:&#xA;#0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:332:7)&#xA;<asynchronous suspension="suspension">&#xA;#1      EventChannel.receiveBroadcastStream.<anonymous closure="closure"> (package:flutter/src/services/platform_channel.dart:676:9)        &#xA;<asynchronous suspension="suspension">&#xA;</asynchronous></anonymous></asynchronous></asynchronous></asynchronous></asynchronous></asynchronous></asynchronous></asynchronous>

    &#xA;

    And i think this comes from abstract class FFmpegKitPlatform extends PlatformInterface inside ffmpeg_kit_flutter_platform_interface.dart, because in there are a lot of functions that are not Implemented.

    &#xA;

    This happens not just because of one functions :

    &#xA;

        // ...&#xA;    final logLevel = await _getLogLevel();&#xA;    print(&#x27;logLevel: $logLevel&#x27;);&#xA;    if (logLevel != null) {&#xA;      FFmpegKitConfig.setLogLevel(logLevel);&#xA;    }&#xA;    final version = FFmpegKitFactory.getVersion();&#xA;    final platform = await FFmpegKitConfig.getPlatform();&#xA;    final arch = await ArchDetect.getArch();&#xA;    final packageName = await Packages.getPackageName();&#xA;    await FFmpegKitConfig.enableRedirection();&#xA;    final isLTSPostfix = (await FFmpegKitConfig.isLTSBuild()) ? "-lts" : "";&#xA;    // ...&#xA;&#xA;

    &#xA;

    All of these Functions and more in FFmpegKitInitializer are not Implemented. So im pretty sure im missing something else here than just some outdated Version.

    &#xA;

    These are my Dependencies :

    &#xA;

    dependencies:&#xA;  flutter:&#xA;    sdk: flutter&#xA;  path_provider: ^2.0.15&#xA;  just_audio: ^0.9.34&#xA;  file_picker: ^5.3.1&#xA;  path: ^1.8.3&#xA;  id3_codec: ^1.0.3&#xA;  ftpconnect: ^2.0.5&#xA;  http: ^1.1.0&#xA;  shared_preferences: ^2.2.0&#xA;  html: ^0.15.5&#xA;  youtube_explode_dart: ^2.3.9&#xA;  intl: ^0.19.0&#xA;  ffmpeg_kit_flutter: ^6.0.3&#xA;

    &#xA;

    Im pretty new to Flutter Development so Im not quiete sure how to go about this Problem because every other FFmpeg Wrapper also has some problems that i couldnt fix.

    &#xA;

    If you need any other Information feel free to ask me, because I also dont know what someone would need to go fix the problem.

  • make fifo pipe in java(windows), write some data into it, let other process read the pipe

    9 novembre 2017, par vs93

    My objective is to create a named pipe(fifo) in windows(java), write some data(coming from camera) into that and invoke ffmpeg command to make mp4 from that data. But I suspect that it is not opening a fifo pipe, rather it is opening a file. How can I make it open a fifo pipe ?
    Here is the code :

    public void run () {
    String mp4Folder = "C://Users/user_2/Desktop/streamDestination";            // Where the MP4 is to be kept
    VFrame frame = null;
    int actualPipeValLen = 0;
    FileOutputStream requestStream = null;
    long lastProcessedTS = 0;
    final String FIFOPATH = "D://FIFO//";
    final String PIPE_NAME = FIFOPATH + "myfifo";
    final String MKFIFOCOMMAND = "mkfifo -m=rw " + PIPE_NAME;
    final String DELFIFOCOMMAND = "rm -r " + PIPE_NAME;
    String mp4FileName = mp4Folder + File.separator + "1.mp4";
    mp4FileName = mp4FileName.replace("\\", "/");
    long firstTimeStamp = 0;
    try {
       Runtime.getRuntime().exec(MKFIFOCOMMAND);
    } catch (IOException e1) {
       e1.printStackTrace();
    }
    if(firstTimeStamp == 0) {
       firstTimeStamp = frame.getTimestamp();
    }
    if((frame.getTimestamp() - firstTimeStamp) > (15 * 1000)) {
       if(requestStream != null) {
           requestStream.close();
           requestStream = null;
       }
       if(actualPipeValLen > 0) {
           String[] ffmpeg = new String[] {"ffmpeg", "-i", PIPE_NAME , "-vcodec", "copy", mp4FileName };
           Process ffmpegProcess = Runtime.getRuntime().exec(ffmpeg);
           actualPipeValLen = 0;
           firstTimeStamp = lastProcessedTS;
           Thread.sleep(2 * 1000);
           try {
               Runtime.getRuntime().exec(DELFIFOCOMMAND);
           } catch (IOException e1) {
               e1.printStackTrace();
           }
           System.exit(0);
       }
    } else {
       System.out.println("Writing into pipe : " + actualPipeValLen);
       if(requestStream == null) {
           requestStream = new  FileOutputStream(PIPE_NAME);
       }
       requestStream.write(frame.getFrame());
       actualPipeValLen += frame.getFrame().length;
       lastProcessedTS = frame.getTimestamp();
    }

    }
