pro_video_editor 1.6.2

pro_video_editor: ^1.6.2 copied to clipboard

• FIX(iOS, macOS): Fixed crash when merging multiple MOV video clips on older devices (e.g., iPhone 7, iOS 15). The issue was caused by AVMutableVideoCompositionInstruction not properly deriving requiredSourceTrackIDs from layer instructions when using a custom video compositor. Introduced CustomVideoCompositionInstruction that explicitly provides source track IDs.

• FIX(iOS, macOS): Fixed video appearing upside down after export due to coordinate system mismatch between AVFoundation (top-left origin) and CIImage (bottom-left origin). The transform is now properly converted between coordinate systems.

• FIX(iOS, macOS): Fixed portrait mode videos being rotated incorrectly after export. The video rotation was being applied twice (once via layer instruction transform and again via orientation correction), causing portrait videos to appear with incorrect pixel orientation despite correct dimensions.
• DEPRECATED(metadata): originalResolution is now deprecated. Use rawResolution instead.
• FIX(android): Video metadata now returns display dimensions (after rotation correction), consistent with iOS/macOS. Previously, Android returned raw dimensions while iOS/macOS returned display dimensions.
• FEAT(metadata): Add rawResolution getter to retrieve the raw video dimensions before rotation is applied.

• FIX(iOS, macOS): Fixed color filters (colorMatrixList), blur, and flip effects being incorrectly applied to overlay images when imageBytesWithCropping is enabled. These effects are now applied only to the video before compositing the overlay.

• FIX(android): Fixed semi-transparent overlay layers appearing darker than expected during video rendering. The issue was caused by double alpha premultiplication — Android's BitmapFactory produces premultiplied pixels while Media3's overlay shader applies alpha again. Pixel data is now converted to straight alpha before uploading to the GPU.

• FEAT(android, iOS, macOS): Add imageBytesWithCropping option to VideoRenderData. When enabled, the image overlay is applied before cropping and gets cropped together with the video instead of being scaled to the final cropped size.

• FIX(android): Fixed black edges appearing around transparent overlay layers during video rendering by using proper ARGB_8888 bitmap configuration and correct alpha blending.

• FIX(iOS, macOS): Fix Swift compiler type-check error by breaking up complex bit-shift expression into sub-expressions.

• FEAT(android, iOS, macOS): Add shouldOptimizeForNetworkUse render option to enable progressive streaming by placing moov atom at file start (fast start). Enabled by default.
• FEAT(android, iOS, macOS): Add isOptimizedForStreaming metadata property to detect if a video has moov before mdat for streaming compatibility.
• FEAT(android, iOS, macOS): Add optional checkStreamingOptimization parameter to getMetadata() for on-demand MP4 atom analysis.

• FEAT(android, iOS, macOS): Add waveform generation with getWaveform method to extract audio peak data for visualization.
• FEAT(android, iOS, macOS): Add streaming waveform generation with getWaveformStream for progressive real-time waveform display.
• FEAT(widgets): Add AudioWaveform widget for static waveform visualization with playback position indicator and seek support.
• FEAT(widgets): Add AudioWaveform.streaming constructor for animated progressive waveform rendering during generation.
• FEAT(android, iOS, macOS): Add WAV format support for audio extraction.

• PERF(android): Improves render performance on Android when mixing with a custom audio track.

• FIX(trim): Improved global trim precision by adding frame compensation to prevent encoder overshoot.

• CHORE: Adjusted code style to comply with lint rules.

• FEAT(android, iOS, macOS): Add hasAudioTrack method to check if a video contains an audio track before attempting extraction.
• FEAT(android, iOS, macOS): Add NO_AUDIO error code and AudioNoTrackException for better error handling when videos have no audio track during extraction.

• FEAT(android, iOS, macOS): Add audio extraction feature with extractAudio and extractAudioToFile methods. Supports MP3, AAC, and M4A formats with optional trimming and bitrate configuration.

• FEAT(android, iOS, macOS): Add video concatenation with videoClips parameter for merging multiple videos.
• FEAT(android, iOS, macOS): Add audio mixing with customAudioPath, originalAudioVolume, and customAudioVolume parameters for enhanced audio control.
• FEAT(android, iOS, macOS): Add jpegQuality parameter to ThumbnailConfigs which allows setting the JPEG quality for thumbnails.
• BREAKING refactor(video_model): Rename RenderVideoModel to VideoRenderData.

• FEAT(android, iOS, macOS): Add ProVideoEditor.instance.cancel(taskId) for cancelling started export tasks.

• FEAT(presets): Add video quality presets for simplified export configuration. Details in PR #55.

• CHORE(android): Update Media3 dependencies to version 1.8.0.

• FIX(windows): Resolve issue of crashing when reading metadata on Windows.

• FEAT(metadata): Add originalResolution to metadata and auto-correct resolution based on video orientation.

• FIX(android): Resolved issue where metadata returned incorrect resolution for rotated videos. This resolves issue #42.

• FEAT: Add renderVideoToFile to return the file path instead of a Uint8List, preventing RAM overload on older devices or when handling larger videos.

• FIX(android): Fixed crash during video export when applying overlay effects. The issue was caused by using ImmutableList.of(bitmapOverlay) instead of a Kotlin-compatible list. This has been resolved by using listOf(bitmapOverlay) instead.
• CHORE(android): Updated media3 dependencies to the latest stable versions for better compatibility and stability.

• FIX(iOS, macOS): Resolved a crash that occurred when setting playback speed below 1x. This resolves issue #29.

• FIX(iOS, macOS): Fixed rotation transforms not properly swapping render dimensions for 90°/270° rotations, resolving squeezed video output with black bars.

• FIX(window, linux, iOS, macOS): Correct bitrate extraction from metadata.
• FIX(android): Remove unsupported WebM output format; Android only supports MP4 generation.
• TEST: Add integration tests for all core functionalities.

• FIX(iOS, macOS): Fixed AVFoundation -11841 "Operation Stopped" errors when exporting videos selected via image_picker package
• FIX(iOS, macOS): Fixed video rotation metadata not being properly handled, causing incorrect orientation in exported videos
• FIX(iOS, macOS): Fixed random video loading failures from image_picker package due to complex transform metadata
• FIX(iOS, macOS): Enhanced video composition pipeline to properly process iPhone camera orientation transforms

• FIX(iOS, macOS): Resolved multiple issue where, in some Swift versions, a trailing comma in the constructor caused an error.

• FIX(iOS, macOS): Resolved an issue where, in some Swift versions, a trailing comma in the constructor caused an error.

• DOCS: Updated README with new examples and images.
