Resolved issue where window would resize itself based on dynamic content
like progress bars and queue updates. Window now maintains the size that
the user sets, regardless of content changes.
**Problem:**
- When progress bars updated or queue content changed, the window would
automatically resize to fit the new content MinSize
- This caused the window to get larger or smaller unexpectedly
- User-set window size was not being preserved
**Solution:**
- Modified setContent() to capture current window size before setting new content
- Restore the window size after SetContent() completes
- This prevents Fyne from auto-resizing based on content MinSize changes
- Window only resizes when user manually drags edges or maximizes
**Impact:**
- Window maintains stable size through all content changes
- Progress bars, queue updates, and module switches no longer trigger resize
- User retains full control of window size via manual resize/maximize
- Improves professional appearance and user experience

Renamed "DVD Author" to "Author" for broader disc production workflow.
Created foundation for complete authoring pipeline with three main tasks:
**Module Structure:**
- Tabbed interface with Chapters, Rip DVD/ISO, and Author Disc tabs
- Added authorChapter struct (timestamp, title, auto-detected flag)
- Added author module state fields (file, chapters, threshold, detecting)
**Chapters Tab (Basic UI):**
- File selection with video probing integration
- Scene detection sensitivity slider (0.1-0.9 threshold)
- Placeholder UI for chapter list and controls
- Add Chapter and Export Chapters buttons (placeholders)
- Foundation for FFmpeg scdet scene detection
**Rip DVD/ISO Tab:**
- Placeholder for high-quality disc extraction
- Will support lossless ripping (like FLAC from CD)
- Preserve all audio/subtitle tracks
**Author Disc Tab:**
- Placeholder for VIDEO_TS/ISO creation
- Will support burn-ready output, NTSC/PAL, menus
Changes:
- Modified main.go: Added authorChapter struct, author state fields,
showAuthorView(), buildAuthorView(), buildChaptersTab(),
buildRipTab(), buildAuthorDiscTab()
- Modified internal/modules/handlers.go: Renamed HandleDVDAuthor to
HandleAuthor with updated comment
- Updated DONE.md with Author module skeleton details
Next steps: Implement FFmpeg scene detection, chapter list UI,
and DVD/ISO ripping functionality.
Added advanced audio channel remixing features for videos with imbalanced
left/right audio channels (e.g., music in left ear, vocals in right ear).
New audio channel options using FFmpeg pan filter:
- Left to Stereo: Copy left channel to both speakers
- Right to Stereo: Copy right channel to both speakers
- Mix to Stereo: Downmix both channels together evenly
- Swap L/R: Swap left and right channels
Changes:
- Updated audioChannelsSelect dropdown with 8 options (was 4)
- Implemented pan filter logic in all 4 FFmpeg command builders:
- buildFFmpegCommandFromJob (main convert)
- DVD encoding function
- Convert command builder
- Snippet generation
- Removed unused "os" import from internal/convert/ffmpeg.go
- Updated DONE.md with audio channel remixing feature
The pan filter syntax allows precise channel routing:
- pan=stereo|c0=c0|c1=c0 (left to both)
- pan=stereo|c0=c1|c1=c1 (right to both)
- pan=stereo|c0=0.5*c0+0.5*c1|c1=0.5*c0+0.5*c1 (mix)
- pan=stereo|c0=c1|c1=c0 (swap)
- Extract reset defaults logic to resetConvertDefaults function
- Add setTargetFileSize helper with syncing guard
- Add syncingTargetSize flag to prevent update loops
- Consolidate reset button handlers to call shared function
- Improves code organization and maintainability
UI Scaling Improvements:
- Reduce module tiles from 160x80 to 150x65
- Reduce title from 20 to 18
- Reduce queue tile from 140x50 to 120x40
- Reduce category labels to 12px
- Reduce padding from 8 to 4px
- Remove scrolling, everything fits in 800x600
Preset UX Improvements:
- Move "Manual" to bottom of all preset dropdowns
- Default bitrate preset: "2.5 Mbps - Medium Quality"
- Default target size: "100MB"
- Manual input fields hidden by default
- Show manual fields only when "Manual" selected
Encoding Preset Order:
- Reverse order: veryslow first, ultrafast last
- Better quality options now appear first
- Applied to both simple and advanced mode
UI Scaling:
- Reduce module tiles from 220x110 to 160x80
- Reduce title size from 28 to 20
- Reduce queue tile from 160x60 to 140x50 with smaller text
- Reduce section padding from 14 to 8 pixels
- Remove extra padding wrapper around tiles
Header Layout Improvements:
- Use border layout with title on left, controls on right
- Compact button labels: "☰ History" → "☰", "Run Benchmark" → "Benchmark"
- Eliminates wasted space in header
Queue Behavior Fix:
- "Clear Completed" always returns to main menu (not last module)
- "Clear All" always returns to main menu
- Prevents unwanted navigation to convert module after clearing
All changes work together to fit app within 800x600 default window
In Progress Tab Enhancements:
- Added animated striped progress bars to in-progress jobs
- Exported ModuleColor function for reuse across modules
- Shows real-time progress (0-100%) with module-specific colors
- Progress updates automatically as jobs run
- Maintains consistent visual style with queue view
Lossless Quality Preset Improvements:
- H.265 and AV1 now support all bitrate modes with lossless quality
- Lossless with Target Size mode now works for H.265/AV1
- H.264 and MPEG-2 no longer show "Lossless" option (codec limitation)
- Dynamic quality dropdown updates based on selected codec
- Automatic fallback to "Near-Lossless" when switching from lossless-capable
codec to non-lossless codec
Quality Options Logic:
- Base options: Draft, Standard, Balanced, High, Near-Lossless
- "Lossless" only appears for H.265 and AV1
- codecSupportsLossless() helper function checks compatibility
- updateQualityOptions() refreshes dropdown when codec changes
Lossless + Bitrate Mode Combinations:
- Lossless + CRF: Forces CRF 0 for perfect quality
- Lossless + CBR: Constant bitrate with lossless quality
- Lossless + VBR: Variable bitrate with lossless quality
- Lossless + Target Size: Calculates bitrate for exact file size with
best possible quality (now allowed for H.265/AV1)
Technical Implementation:
- Added Progress field to ui.HistoryEntry struct
- Exported StripedProgress widget and ModuleColor function
- updateQualityOptions() function dynamically filters quality presets
- updateEncodingControls() handles lossless modes per codec
- Descriptive hints explain each lossless+bitrate combination
This allows professional workflows where lossless quality is desired
but file size constraints still need to be met using Target Size mode.
Features:
- New "In Progress" tab shows running/pending jobs
- Displays active jobs without opening full queue
- Tab positioned first for quick visibility
- Shows "Running..." or "Pending" status
- No delete button on active jobs (only completed/failed)
Implementation:
- Updated BuildHistorySidebar to accept activeJobs parameter
- Converts queue.Job to ui.HistoryEntry for display
- Filters running/pending jobs from queue
- Conditional delete button (nil check)
- Dynamic status text based on job state
UX Improvements:
- Quick glance at current activity without queue view
- Three-tab layout: In Progress → Completed → Failed
- Consistent styling with existing history entries
- Tappable entries to view full job details
This allows users to monitor active conversions directly
from the history sidebar, reducing the need to constantly
check the full job queue view.
Bitrate Mode Options Now Show:
- CRF (Constant Rate Factor)
- CBR (Constant Bitrate)
- VBR (Variable Bitrate)
- Target Size (Calculate from file size)
Implementation:
- Added bidirectional mapping between short codes and full labels
- Internally still uses short codes (CRF, CBR, VBR, Target Size)
- Preserves compatibility with existing config files
- Maps display label to internal code on selection
- Maps internal code to display label when loading
Makes it immediately clear what each bitrate mode does without
needing to reference documentation or tooltips.
Command Preview Button:
- Disabled when no video source is loaded
- Shows "Show Preview" when preview is hidden
- Shows "Hide Preview" when preview is visible
- Makes it clear when and why the button can be used
Format Options Reorganization:
- Grouped formats by codec family for better readability
- Order: H.264 → H.265 → AV1 → VP9 → ProRes → MPEG-2
- Added comments explaining each codec family
- Makes it easier to find and compare similar codecs
This improves discoverability and reduces user confusion about
when the command preview is available and which format to choose.
Features:
- Add "×" delete button to each history entry in sidebar
- Click to remove individual entries from history
- Automatically saves and refreshes sidebar after deletion
Bug Fixes:
- Fix nil pointer crash when opening Convert module
- Fixed widget initialization order: bitrateContainer now created
AFTER bitratePresetSelect is initialized
- Prevented "invalid memory address" panic in tabs layout
Technical Details:
- Added deleteHistoryEntry() method to remove entries by ID
- Updated BuildHistorySidebar signature to accept onEntryDelete callback
- Moved bitrateContainer creation from line 5742 to 5794
- All Select widgets now properly initialized before container creation
The crash was caused by bitrateContainer containing a nil
bitratePresetSelect widget, which crashed when Fyne's layout system
called .Visible() during tab initialization.
- Fix panic when closing log viewer (duplicate channel close)
- Improve CBR: Set bufsize to 2x bitrate for better encoder handling
- Improve VBR: Increase maxrate cap from 1.5x to 2x target bitrate
- Add bufsize to VBR at 4x target (2x maxrate) to enforce caps
- Update VBR hint to reflect 2x peak cap and 2-pass encoding
This eliminates runaway bitrates while maintaining quality peaks.
Restructured bitrate controls to hide unused options based on mode,
and improved VBR encoding to use 2-pass for accurate bitrate targeting.
UI Improvements:
- Wrapped CRF, bitrate, and target size controls in hideable containers
- Only show relevant controls based on selected bitrate mode:
* CRF mode: Show only CRF entry
* CBR mode: Show only bitrate entry and presets
* VBR mode: Show only bitrate entry and presets
* Target Size mode: Show only target size controls
- Added descriptive hints for each mode explaining behavior
- Updated DVD mode to work with new container structure
- Made command preview update when bitrate settings change
Encoding Improvements:
- VBR now uses maxrate at 1.5x target for quality peaks
- VBR automatically enables 2-pass encoding for accuracy
- CBR remains strict (minrate=maxrate=target) for guaranteed bitrate
- Target Size mode continues to calculate exact bitrate from duration
This addresses runaway bitrate issues by:
1. Making it clear which mode is active
2. Hiding confusing unused controls
3. Ensuring VBR hits target average bitrate with 2-pass
4. Keeping CBR strict for exact constant bitrate
Pros of manual bitrate targeting:
- Predictable file sizes
- Meets strict size requirements
- Good for streaming with bandwidth constraints
Cons of manual bitrate targeting:
- Variable quality (simple scenes waste bits, complex scenes starve)
- Less efficient than CRF overall
- Requires 2-pass for VBR accuracy (slower)
Added support for modern video codecs and containers, and made the
FFmpeg command preview update in real-time as settings change.
Format additions:
- MP4 (AV1) - AV1 codec in MP4 container
- MKV (AV1) - AV1 codec in Matroska container
- WebM (VP9) - VP9 codec for web video
- WebM (AV1) - AV1 codec for web video
- MOV (H.264) - H.264 in QuickTime for Apple compatibility
- MOV (H.265) - H.265 in QuickTime for Apple compatibility
Command preview improvements:
- Added forward declaration for buildCommandPreview function
- Command preview now updates live when changing:
* Format selection
* Video codec
* Quality presets (Simple and Advanced)
* Encoder speed presets
- Preview stays synchronized with current settings
- Users can now see exactly what command will be generated
This gives professionals comprehensive format options while keeping
the preview accurate and up-to-date.
Made the FFmpeg command preview less intrusive by adding a toggle button
and showing actual file paths instead of placeholders.
Changes:
- Added convertCommandPreviewShow state field to track preview visibility
- Added "Command Preview" toggle button next to "View Queue" button
- Command preview now hidden by default to save screen space
- Preview shows actual input/output file paths instead of INPUT/OUTPUT
- Cover art paths also shown with real file path when present
This makes the interface cleaner while providing more useful information
when the preview is needed.
