Simple GUI toolset for FFmpeg

The queue callback was triggering showMainMenu() from a goroutine (the
job processor) without marshaling to the main thread. This caused the
threading error "should have been called in fyne.Do[AndWait]".
Changes:
1. Queue callback now wraps all UI updates in app.Driver().DoFromGoroutine()
to safely marshal calls from the job processor goroutine to the main thread
2. setContent() now always uses DoFromGoroutine() to ensure thread safety
regardless of caller context. This prevents errors when called from
callbacks or other goroutines.
3. Added fallback for early initialization when app driver isn't ready yet
This ensures all UI updates happen on the main Fyne event loop thread.

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 withVIDEOTOOLS_LOG_FILE=/path/to/log). - CLI command
videotools logs(orgo 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.
