Usage #

Basic Example #

import 'package:native_media_converter/native_media_converter.dart';

// Listen for progress updates
NativeMediaConverter.progressStream().listen((progress) {
  print('Conversion progress: ${(progress * 100).toStringAsFixed(1)}%');
});

// Configure conversion options
final options = ConvertOptions(
  inputPath: '/path/to/input/video.mp4',
  outputPath: '/path/to/output/video.mp4',
  width: 1280,
  // width/height are derived from `resolution` and input orientation on the native side
  resolution: 720,
  fps: 30,
  videoBitrate: 2000000,
  codec: "h264",
  container: "mp4",
  hdr: HDROptions(isHdr: false),
);

try {
  // Start conversion
  final outputPath = await NativeMediaConverter.transcode(options);
  print('Video converted successfully: $outputPath');
} catch (e) {
  print('Conversion failed: $e');
}
