From 42af5336273afa28be292cc6c51b3e154460c815 Mon Sep 17 00:00:00 2001 From: Stu Leak Date: Wed, 17 Dec 2025 19:08:48 -0500 Subject: [PATCH] Phase 1: Add FFmpeg command copy infrastructure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the foundation for FFmpeg command copy functionality: 1. Created FFmpegCommandWidget (components.go): - Displays FFmpeg commands in scrollable monospace text - Includes "Copy Command" button with clipboard integration - Shows confirmation dialog when copied - Reusable widget for consistent UI across modules 2. Created buildFFmpegCommandFromJob() function (main.go): - Extracts FFmpeg command from queue job config - Uses INPUT/OUTPUT placeholders for portability - Handles video filters (deinterlace, crop, scale, aspect, flip, rotate, fps) - Handles video codecs with hardware acceleration (H.264, H.265, AV1, VP9) - Handles quality modes (CRF, CBR, VBR) - Handles audio codecs and settings - Covers ~90% of convert job scenarios This infrastructure enables users to copy the exact FFmpeg command being used for conversions, making it easy to reproduce VideoTools' output in external tools like Topaz or command-line ffmpeg. Next phase will integrate this into the Convert module UI, queue view, and conversion history sidebar. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- internal/ui/components.go | 52 ++++++++ main.go | 272 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 324 insertions(+) diff --git a/internal/ui/components.go b/internal/ui/components.go index 48ed713..90e7c7f 100644 --- a/internal/ui/components.go +++ b/internal/ui/components.go @@ -653,3 +653,55 @@ func formatCount(count int, label string) string { } return fmt.Sprintf("%d %s", count, label) } + +// FFmpegCommandWidget displays an FFmpeg command with copy button +type FFmpegCommandWidget struct { + widget.BaseWidget + command string + commandLabel *widget.Label + copyButton *widget.Button + window fyne.Window +} + +// NewFFmpegCommandWidget creates a new FFmpeg command display widget +func NewFFmpegCommandWidget(command string, window fyne.Window) *FFmpegCommandWidget { + w := &FFmpegCommandWidget{ + command: command, + window: window, + } + w.ExtendBaseWidget(w) + + w.commandLabel = widget.NewLabel(command) + w.commandLabel.Wrapping = fyne.TextWrapBreak + w.commandLabel.TextStyle = fyne.TextStyle{Monospace: true} + + w.copyButton = widget.NewButton("Copy Command", func() { + window.Clipboard().SetContent(w.command) + dialog.ShowInformation("Copied", "FFmpeg command copied to clipboard", window) + }) + w.copyButton.Importance = widget.LowImportance + + return w +} + +// SetCommand updates the displayed command +func (w *FFmpegCommandWidget) SetCommand(command string) { + w.command = command + w.commandLabel.SetText(command) + w.Refresh() +} + +// CreateRenderer creates the widget renderer +func (w *FFmpegCommandWidget) CreateRenderer() fyne.WidgetRenderer { + scroll := container.NewVScroll(w.commandLabel) + scroll.SetMinSize(fyne.NewSize(0, 80)) + + content := container.NewBorder( + nil, + container.NewHBox(layout.NewSpacer(), w.copyButton), + nil, nil, + scroll, + ) + + return widget.NewSimpleRenderer(content) +} diff --git a/main.go b/main.go index c16b5bb..c90da56 100644 --- a/main.go +++ b/main.go @@ -4139,6 +4139,278 @@ func (s *appState) executeUpscaleJob(ctx context.Context, job *queue.Job, progre return nil } +// buildFFmpegCommandFromJob builds an FFmpeg command string from a queue job with INPUT/OUTPUT placeholders +func buildFFmpegCommandFromJob(job *queue.Job) string { + if job == nil || job.Config == nil { + return "" + } + + cfg := job.Config + args := []string{"-y", "-hide_banner", "-loglevel", "error"} + + // Input + args = append(args, "-i", "INPUT") + + // Cover art if present (convert jobs only) + if job.Type == queue.JobTypeConvert { + if coverArtPath, _ := cfg["coverArtPath"].(string);
