Installation #

To use veo in your Dart project, add it as a dependency using dart pub add: bash dart pub add veo

Usage #

Here are some examples of how to use the veo package:

1. Getting Video Metadata: dart import 'package:veo/veo.dart';

void main() async { try { final videoPath = 'path/to/your/video.mp4'; // Replace with your video file path final metadata = await VideoProcessor.getMetadata(videoPath);

print('Duration: ${metadata.duration}');
print('Width: ${metadata.width}');
print('Height: ${metadata.height}');
print('Frame Rate: ${metadata.frameRate}');

} catch (e) { print('Error getting metadata: $e'); } }

2. Extracting Frames from a Video: dart import 'package:veo/veo.dart'; import 'dart:io';

void main() async { try { final videoPath = 'path/to/your/video.mp4'; // Replace with your video file path final outputDirectory = 'path/to/output/directory'; // Replace with your desired output directory

// Ensure the output directory exists
Directory(outputDirectory).createSync(recursive: true);

await VideoProcessor.extractFrames(
  videoPath,
  outputDirectory,
  frameRate: 1, // Extract one frame per second
);

print('Frames extracted successfully to $outputDirectory');

} catch (e) { print('Error extracting frames: $e'); } }

3. Converting Video Format: dart import 'package:veo/veo.dart';

void main() async { try { final inputPath = 'path/to/your/video.mp4'; // Replace with your input video file path final outputPath = 'path/to/your/output/video.avi'; // Replace with your desired output video file path

await VideoProcessor.convertFormat(inputPath, outputPath, format: 'avi');

print('Video converted successfully to AVI format at $outputPath');

} catch (e) { print('Error converting video: $e'); } }

4. Generating a Thumbnail: dart import 'package:veo/veo.dart'; import 'dart:io';

void main() async { try { final videoPath = 'path/to/your/video.mp4'; // Replace with your video file path final thumbnailPath = 'path/to/your/thumbnail.jpg'; // Replace with your desired thumbnail file path

await VideoProcessor.generateThumbnail(videoPath, thumbnailPath, time: Duration(seconds: 5));

print('Thumbnail generated successfully at $thumbnailPath');

} catch (e) { print('Error generating thumbnail: $e'); } }

5. Resizing a Video: dart import 'package:veo/veo.dart';

void main() async { try { final inputPath = 'path/to/your/video.mp4'; // Replace with your input video file path final outputPath = 'path/to/your/resized_video.mp4'; // Replace with your desired output video file path

await VideoProcessor.resize(inputPath, outputPath, width: 640, height: 480);

print('Video resized successfully and saved at $outputPath');

} catch (e) { print('Error resizing video: $e'); } }
