v_thumbnail 0.1.1

Generate thumbnail from video

Changelog

All notable changes to this project will be documented in this file.

0.1.0 - 2026-08-23

Fixed

• Native work (Android MediaMetadataRetriever, iOS AVAssetImageGenerator) now runs on a background thread/queue instead of the platform thread, so thumbnail generation no longer blocks the UI.
• Android no longer force-unwraps a possibly-null decoded frame; a failed extraction now returns a proper THUMBNAIL_ERROR instead of crashing.
• Thumbnails are written to the OS-managed cache directory (cacheDir / .cachesDirectory) instead of a raw temp file, so they get cleaned up automatically under storage pressure.

Added

• generateMultipleThumbnails is now actually implemented on Android and iOS (previously unimplemented on both platforms and would return notImplemented). Frames are spread evenly across the video duration, reusing a single retriever/generator instance per call.

Changed

• Android decodes frames at the target size via getScaledFrameAtTime (API 27+, falls back to decode-then-scale on older devices) instead of always decoding at full resolution.
• Android plugin package changed from the placeholder com.example.v_thumbnail to com.performance2024.vthumbnail.
