Frame Extractor v1.1.1

Fixed

Android

• Frame extraction now works correctly - ffmpeg output is written to the app's writable directory (Android/data/com.nokarin.frameextractor/files/) instead of trying to write directly to /storage/emulated/0/ which is blocked by Android 10+ Scoped Storage
• YouTube download now uses the app's cache directory, fixing Operation not permitted error when downloading to external storage
• SAF (Storage Access Framework) URI resolution improved with proper fallback to writable app directory

Added

User Interface

• Mouse cursor changes to pointer on all interactive elements (buttons, chips, sliders, file rows, tabs)
• Text cursor shown on text input fields
• Hint bar below Extract button — explains what needs to be selected before extraction can start
• Clear button on video file and output folder rows for quick reset
• Hover effect on file/folder rows using borderHi color
• Hover effect on Extract and Cancel buttons (brighter fill on hover)
• Toast notifications now include an icon (check, error, cancel)
• Progress card background tinted by phase: blue for extraction, red for YouTube download
• Log panel: color-coded log lines — [ERR] red, [WARN] orange, [INFO]/[Android]/[Copy] blue
• Log line count badge in log panel header

Settings & UX

• All extraction settings (FPS, quality, format, time range) are disabled until video source and output folder are both selected
• Tooltip on disabled settings card explaining what needs to be selected
• Source tab switching and YouTube quality chips are disabled during active extraction
• Advanced options toggle is disabled when settings are not yet unlocked
• Default output format changed from PNG to JPG (smaller file size)
• Default quality changed from 100% to 90%
• "Open folder when done" toggle now has a subtitle description

Changed

UI

• Progress card is now shown/hidden dynamically instead of always visible

Release Notes

Android

Due to Scoped Storage (Android 10+), extracted frames are saved in:
Android/data/com.nokarin.frameextractor/files/

You can access them via:
Files → Internal Storage → Android → data → com.nokarin.frameextractor → files

iOS

YouTube extraction uses youtube_explode_dart.
Running external binaries (like yt-dlp) is not allowed due to Apple's sandbox policy.

Desktop (Windows / Linux / macOS)

ffmpeg and yt-dlp are bundled inside the app.

On first launch, required binaries are extracted to:

• Installer:
  • Windows: %AppData%\FrameExtractor\bin\
  • Linux: ~/.local/share/FrameExtractor/bin/
• Portable:
  • bin/ folder next to the executable
