Using FFmpeg in Flutter to Compress and Delete Video Files

When working on Flutter apps that handle video files, managing storage efficiently becomes crucial. Large video files can be problematic, especially for apps with limited storage space. Fortunately, FFmpeg offers a robust solution for compressing video files. In this blog, we will explore how to compress a video file and delete the original one using FFmpeg in Flutter.

Prerequisites

Before we dive into the code, ensure that you have:

Flutter installed on your machine.

Basic knowledge of Dart and Flutter.

FFmpeg plugin integrated into your Flutter project.

Adding FFmpeg to Your Flutter Project

To use FFmpeg within Flutter, you need to add the flutter_ffmpeg package to your pubspec.yaml file:

Detailed Breakdown

Initialize FlutterFFmpeg: Create an instance of FlutterFFmpeg.

Get Temporary Directory: Use path_provider to get a temporary directory path where the compressed file can be stored.

Build the FFmpeg Command: We're using libx264 codec and setting the -crf (Constant Rate Factor) to 28 for compression. The CRF scale ranges from 0 to 51. Lower values mean better quality but larger files.

Execute the Command: Use the .execute(command) method to run the FFmpeg command. This method returns a result code. A result of 0 indicates success.

Delete Original File: If the compression is successful, delete the original file to save space.

Conclusion

In this post, we walked through the process of compressing a video file and optionally deleting the original using FFmpeg in Flutter. This not only helps in managing app storage efficiently but also ensures that your app remains lightweight and responsive. Integrate these concepts into your Flutter projects to handle video files like a pro.

Happy coding!
