A Digital Media Primer for Geeks
24 septembre 2010, par noreply@blogger.com (John Luther)Our friend Monty Montgomery (creator of the Vorbis audio codec used in WebM) has started a video series about digital media. The first episode is an excellent overview of "the technical foundations of modern digital media."
You can stream WebM versions of the video in your favorite WebM-enabled browser or download it to your desktop and watch it one of many WebM-enabled media players. Supported browsers and players are listed on our site.

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

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.
