Add comprehensive DVD-Video encoding functionality: - New internal/convert package with modular architecture - types.go: Core types (VideoSource, ConvertConfig, FormatOption) - ffmpeg.go: FFmpeg codec mapping and video probing - presets.go: Output format definitions - dvd.go: NTSC-specific DVD encoding and validation - dvd_regions.go: PAL, SECAM, and multi-region support - New internal/app/dvd_adapter.go for main.go integration Features implemented: ✓ DVD-NTSC preset (720×480@29.97fps, MPEG-2/AC-3) ✓ Multi-region support (NTSC, PAL, SECAM - all region-free) ✓ Comprehensive validation system with actionable warnings ✓ Automatic framerate conversion (23.976p, 24p, 30p, 60p) ✓ Audio resampling to 48 kHz ✓ Aspect ratio handling (4:3, 16:9, letterboxing) ✓ Interlacing detection and preservation ✓ DVDStyler-compatible output (no re-encoding) ✓ PS2-safe bitrate limits (max 9000 kbps) Complete technical specifications and integration guide in: - DVD_IMPLEMENTATION_SUMMARY.md All packages compile without errors or warnings. Ready for integration with existing queue and UI systems. |

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.
