media_tool_flutter 0.1.2

Video, image and audio conversion and manipulation via native platform code.

Media Tool Flutter

Video, image and audio processing via native platform code.

🚧 WIP 🚧

Only Apple (iOS & macOS) support is implemented via native code yet. The Android implementation is mocked using FFmpeg.

• Resize
• Frame rate adjustment
• Audio track manipulataion
• Alpha channel and HDR handling
• Slow motion support
• Metadata preserving
• Hardware acceleration

• Progress and cancellation

Codecs

Video: H.264, H.265/HEVC and ProRes.

Audio: AAC, Opus and FLAC.

Example

// Compress video file
final task = VideoTool.compress(
  id: id, // unique id
  path: path,
  destination: destination,
  // Video
  videoSettings: const VideoSettings(
    codec: VideoCodec.h264,
    bitrate: 2000000, // 2 Mbps
    size: Size(1280.0, 1280.0), // size to fit in
    // quality, frame rate, atd.
  ),
  // Audio
  skipAudio: false,
  audioSettings: const AudioSettings(
    codec: AudioCodec.opus, 
    bitrate: 96000, // 96 Kbps
    // sample rate, quality, atd.
  ),
  // Metadata and file options
  skipMetadata: false,
  overwrite: true,
  deleteOrigin: false
);

// State notifier
task.events.listen(print);

// Cancellation
task.cancel();

Image

Features:

• Convert with multiple formats
• Resize and crop
• Frame rate adjustment
• Animated image sequences support
• Alpha channel and HDR handling
• Metadata and orientation preserving
• Image information gathering

Formats:

• JPEG
• PNG and APNG
• GIF
• TIFF
• BMP
• WEBP
• HEIF

Example

// Convert image file
final metadata = await ImageTool.compress(
  path: path,
  destination: destination,
  settings: const ImageSettings(
    format: ImageFormat.png,
    size: Size(1280.0, 1280.0),
    crop: false, // crop or fit
    // frame rate, quality, alpha channel, background color, atd.
  ),
  skipMetadata: false,
  overwrite: true,
  deleteOrigin: false
);

Audio

Features:

• Compress with multiple codecs
• Metadata preserving
• Hardware acceleration
• Audio information gathering
• Progress and cancellation

Codecs:

• AAC
• Opus
• FLAC

Example

// Compress audio file
final task = AudioTool.compress(
  id: id, // unique id
  path: path,
  destination: destination,
  settings: const AudioSettings(
    codec: AudioCodec.opus, 
    bitrate: 96000, // 96 Kbps
    // sample rate, quality, atd.
  ),
  skipMetadata: false,
  overwrite: true,
  deleteOrigin: false
);

// State notifier
task.events.listen(print);

// Cancellation
task.cancel();

Internally

Each plugin methods which run platform code do support multiple parallel executions, each of execution has it's own progress, cancellation and error handling. Main tests stored at integration_test.
