Simple GUI toolset for FFmpeg

Stu 18a14c6020 Refactor to modular architecture with rainbow UI (v0.1.0-dev8)
Major refactoring to improve code organization and enhance UI:

Architecture:
- Split monolithic main.go into modular internal/ package structure
- Created internal/logging for centralized logging system
- Created internal/modules for module handler functions
- Created internal/ui for UI components and layouts
- Created internal/utils for shared utility functions

UI Enhancements:
- Implemented rainbow gradient across 8 module buttons (violet→red)
- Increased module button text size to 20 for better readability
- Fixed text centering on module tiles
- Converted Simple/Advanced mode toggle to tabs to save vertical space
- Added vertical scrollbars to prevent UI overflow
- Added metadata copy button (📋) to copy all metadata to clipboard

Video Processing:
- Fixed aspect ratio conversion to default to center-crop behavior
- Added 6 aspect handling modes: Auto, Crop, Letterbox, Pillarbox, Blur Fill, Stretch
- Fixed blur fill to maintain source resolution with padding (no scaling)
- Ensured all FFmpeg filters produce even-numbered dimensions for H.264

Known Issues:
- WMV files still produce FFmpeg error 234 during aspect conversions
  (requires codec-specific handling in future update)

VideoTools Prototype

Requirements

  • Go 1.21+
  • Fyne 2.x (pulled automatically via go mod tidy)
  • FFmpeg (not yet invoked, but required for future transcoding)

Running

Launch the GUI:

go run .

Run a module via CLI:

go run . convert input.avi output.mp4
go run . combine file1.mov file2.wav / final.mp4
go run . logs

Add -debug or VIDEOTOOLS_DEBUG=1 for verbose stderr logs.

Logs

  • All actions log to videotools.log (override with VIDEOTOOLS_LOG_FILE=/path/to/log).
  • CLI command videotools logs (or go run . logs) prints the last 200 lines.
  • Each entry is tagged (e.g. [UI], [CLI], [FFMPEG]) so issues are easy to trace.

Notes

  • GUI requires a running display server (X11/Wayland). In headless shells it will log [UI] DISPLAY environment variable is empty.
  • Convert screen accepts drag-and-drop or the "Open File…" button; ffprobe metadata populates instantly, the preview box animates extracted frames with simple play/pause + slider controls (and lets you grab cover art), and the "Generate Snippet" button produces a 20-second midpoint clip for quick quality checks (requires ffmpeg in PATH).
  • Simple mode now applies smart inverse telecine by default—automatically skipping it on progressive footage—and lets you rename the target file before launching a convert job.
  • Other module handlers are placeholders; hook them to actual FFmpeg calls next.
