FFmpegKitFlutter, Error : MissingPluginException(No implementation found for method ffmpegSession on channel flutter.arthenica.com/ffmpeg_kit)
12 février, par 7SolomonI Have this simple Flutter function, to compress Audio Files


import 'package:ffmpeg_kit_flutter/ffmpeg_kit.dart';
import 'package:ffmpeg_kit_flutter/return_code.dart';


Future<string> compressAudio(String inputPath) async {
 try {
 // ...
 final command = '-y -i "$inputPath" ' // Input file
 '-af "loudnorm=I=-16:TP=-1.5:LRA=11,' // Loudness normalization
 'acompressor=threshold=${_config['threshold_db']}:'
 'ratio=${_config['ratio']}:'
 'attack=${_config['attack']}:'
 'release=${_config['release']},'
 'highpass=f=20,lowpass=f=20000" ' // Audio filters
 '-ar 44100 ' // Sample rate
 '-b:a 128k ' // Bitrate
 '-codec:a libmp3lame ' // MP3 encoder
 '-q:a 2 ' // Quality setting for LAME (0-9, lower is better)
 '-map_metadata 0 ' // Copy metadata
 '"$outputPath"'; // Output file

 // Execute FFmpeg command
 final session = await FFmpegKit.execute(command);
 final returnCode = await session.getReturnCode();
 final logs = await session.getLogs();
 print('FFmpeg logs: $logs');

 if (ReturnCode.isSuccess(returnCode)) {
 return outputFileName;
 } else {
 final logs = await session.getLogs();
 throw Exception(
 'FFmpeg process failed with code $returnCode\nLogs: $logs');
 }
 } catch (e, stackTrace) {
 print('Error: $e');
 print('Stack trace: $stackTrace');
 throw Exception('Failed to compress audio: $e\nStack trace: $stackTrace');
 }
 }
</string>

And I get this error

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

This is the Stacktrace


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

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.


This happens not just because of one functions :


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



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.


These are my Dependencies :


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


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.


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.

What is the easiest way to merge GIF and Audio files into one Video file using FFMPEG
7 avril 2021, par Mouaad Abdelghafour AITALII have an audio file and GIF, I would like to merge both of them into one video file, I've done the following :


Converting GIF into Video


Looping the output video X time
X = (int) (audioDuration / 1000.0) / gifDuration;

Merge the final video with the audio


FFmpeg commands :


Converting GIF into Video


-f gif -y -i input.gif -c:a copy -c:v libx265 -crf 26 -preset ultrafast -s 1080*1920 -pix_fmt yuv420p -map 0 gif2video.mp4


Looping the output video X time


-y -stream_loop " + X + " -i gif2video.mp4 -c copy looped_output.mp4


Merge the final video with the audio :


-y -i looped_output.mp4 -i audio.mp3 -c:v copy -c:a aac final_output.mp4


The above command works, but sometimes the output video export with one GIF frame (no animation) and audio
