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.
