media_metadata 2.2.2

A Flutter plugin to read metadata from media files (audio and video) on Android, iOS, macOS, Windows, and Linux.

2.2.2

• Fixed implicit coercion warnings by explicitly casting the image metadata dictionary as [String: Any?] and resolved a target compilation error on macOS 10.15 by replacing modern UTType APIs with legacy constants.

2.2.1

• Fixed implicit coercion warnings in MediaMetadataPlugin.swift by explicitly casting the image metadata dictionary as [String: Any?].

2.2.0

Fixed

• Compilation Errors (Linux):
  • Fixed a typo where fl_value_int was called instead of fl_value_new_int when setting the bitsPerSample property for MP4 files.
  • Resolved no member named 'videoWidth' / 'videoHeight' in 'TagLib::MP4::Properties' errors by removing the non-existent video property getters, as TagLib focuses exclusively on audio metadata.
  • Fixed an unclosed brace (}) and conditional block mismatch inside read_media_metadata that previously triggered function definition is not allowed here and expected '}' build failures.

Dependency & Platform Updates

• Dependencies: Updated FilePicker version and removed the Web version in pubspec.yaml.
• iOS / macOS: Updated the .podspec files.
• Windows: The plugin now utilizes the Shell Property Store to read metadata.
• Example App: Fully updated to reflect all new features and changes.

New Features & Thumbnail Generation

• Video Thumbnails: Added a new parameter to the read function to explicitly enable preview thumbnail generation for video metadata.
• ImageMetadata.isGenerated Property: - Returns false for genuine embedded cover art or standalone image files.
  • Returns true only for thumbnails generated from a video frame.
• createThumbnail Parameter: (Added to MediaMetadata.read, defaults to false):
  • This only triggers for video files that do not have actual embedded cover art.
• Write Protection: MediaMetadata.write now intentionally ignores any image marked with isGenerated: true to prevent saving a generated thumbnail as if it were genuine cover art.

Platform-Specific Implementation Details

• Android: Uses MediaMetadataRetriever.getFrameAtTime for thumbnail generation.
• iOS / macOS: Uses AVAssetImageGenerator for thumbnail generation. Remove the PrivacyInfo file for remove the warning.
• Windows: Re-introduced IShellItemImageFactory—but only under the explicit createThumbnail flag and strictly for video extensions (never for audio, and never silently in the background).
• Linux: Spawns an ffmpeg subprocess if installed. If ffmpeg is missing, no thumbnail is generated (does not fall back to a generic icon).

Documentation & UI

• Example App UI: Added a "Generate thumbnail for videos" toggle switch and a visual "GENERATED" badge on the thumbnail preview when applicable.
• README: Fully rewritten to accurately reflect the current state of the codebase (covering ImageMetadata, comments, technical audio/video fields, createThumbnail, and Linux ffmpeg setup instructions).

2.0.0

• iOS and macOS versions are now functional, and added metadata writing, which is partially functional and MIT Licence.
