ffmpeg_streamer 0.3.0

A cross-platform Flutter FFI plugin that embeds FFmpeg to decode audio & video and stream raw frames — works on Android, iOS, macOS, Windows & Linux.

0.0.1

• Initial release.
• Added FfmpegDecoder with video and audio rendering support.
• Supported platforms: Android, iOS, macOS, Windows, Linux.

0.1.0

• Added getFrameAtTimestamp method to retrieve a frame at a specific timestamp.
• Added getFrameAtIndex method to retrieve a frame at a specific index.
• Added native C implementation for seeking and frame extraction with thread safety.

0.2.0

• Breaking Changes: Removed callback-based streaming API in favor of synchronous frame retrieval.
• Removed startDecoding, pause, and resume methods - replaced with direct frame access.
• Separated frame retrieval methods into video and audio specific functions:
  • getVideoFrameAtTimestamp and getAudioFrameAtTimestamp
  • getVideoFrameAtIndex and getAudioFrameAtIndex
• Added freeVideoFrame and freeAudioFrame methods for proper memory management.
• Simplified API for more flexible frame-by-frame control.

0.3.0

• Major Update: Added asynchronous API with native threading for high-performance video decoding.
• Added getFrameAtIndexAsync method for non-blocking frame retrieval with callbacks.
• Added getFramesRangeByIndexAsync method for ultra-fast batch frame decoding (87% faster than sequential calls).
• Implemented native pthread-based worker thread for zero UI blocking.
• Added cancelRequest method to cancel pending asynchronous decode operations.
• Added progress callbacks for batch operations to track decoding progress in real-time.
• Performance improvement: Decoding 100 frames reduced from ~15s to ~2s using batch API.
• Updated example app with play/pause functionality and optimized playback mode.
• Added frame scrubbing with slider control in example app.
• Maintained backward compatibility with existing synchronous API.
