Simple GUI toolset for FFmpeg

Previously, when a conversion was started and the user navigated away from the Convert module and returned, the progress stats would freeze (though the progress bar would continue animating). This was caused by the conversion goroutine updating stale widget references. Changes: - Decoupled conversion state from UI widgets - Conversion goroutine now only updates appState (convertBusy, convertStatus) - Added 200ms UI refresh ticker in buildConvertView to update widgets from state - Removed all direct widget manipulation from background conversion process This ensures conversion progress stats remain accurate and update correctly regardless of module navigation, supporting the persistent video context design where conversions continue running while users work in other modules. |

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.
