Added -show_chapters flag to ffprobe command to retrieve chapter
information. Parse chapters from JSON output and set HasChapters
field when chapters are present.
Files with chapters will now correctly show 'Chapters: Yes' in
the file information display.
Added explicit stream mapping to preserve all streams:
- Map video, audio, and subtitle streams (subtitles optional)
- Added -map_chapters to preserve chapter information
- Added -map_metadata to preserve all file metadata
- Copy subtitle streams without re-encoding
Applies to both conversions with and without cover art.
Works for all output formats that support these features.
Removed -target ntsc-dvd and -target pal-dvd preset flags which
strip metadata including chapters. Instead, manually specify all
DVD parameters (bitrate, maxrate, bufsize, format) to maintain
full control and preserve chapter metadata.
Chapters now retained in both new 'dvd' format and legacy DVD formats.
When 'Clear Completed' empties the queue, return to the previous
module instead of staying in an empty queue view. If jobs remain
after clearing, stay in queue view and refresh.
Changed 'Clear All' behavior to return to the last active module
instead of always going to main menu. Falls back to main menu
if no previous module is tracked or if coming from queue itself.
Added clearer format descriptions:
- "Fast Merge (No Re-encoding)" instead of "MKV (Copy streams)"
- "Lossless MKV (Best Quality)" - new option with slow preset, CRF 18, FLAC audio
- "High Quality MP4 (H.264/H.265)" instead of technical codec names
- "DVD Format" with conditional region/aspect selectors
- "Blu-ray Format" instead of "Blu-ray (H.264)"
DVD Format improvements:
- When "DVD Format" is selected, shows Region (NTSC/PAL) and Aspect (16:9/4:3) options
- Options hidden for other formats
- Stored in state and passed to merge job config
- Updated execution to use DVD region/aspect settings
Maintains backward compatibility with legacy DVD format codes.
Removed cancelRunningLocked() call from Clear() method.
Now 'Clear Completed' only removes completed/failed/cancelled jobs
and preserves pending/running/paused jobs.
Previously it was cancelling active jobs before filtering, causing
running jobs (like merges) to be removed from the queue.
WMV Encoder Fix:
- WMV files now use wmv2 encoder (ffmpeg compatible) instead of wmv3
- Audio uses wmav2 for WMV files
- High quality bitrate (2000k) for WMV video
- Fallback handling for unsupported source codecs
UI Simplification:
- Changed "High Quality (source format/codecs)" to "Match Source Format"
- Simplified hint text to just "Unchecked = Use Conversion Settings"
- More concise and less confusing labels
Snippet Quality Improvements:
- High Quality mode now detects and uses source codecs (WMV stays WMV)
- Uses conversion panel's encoder preset (e.g., 'slow') instead of hardcoded 'ultrafast'
- Uses conversion panel's CRF setting for quality control
- Outputs to source file extension in High Quality mode
- Updated UI label to "High Quality (source format/codecs)"
Workflow Streamlining:
- Removed popup dialog when loading multiple videos
- Showing convert view is sufficient feedback
- Failed files logged instead of shown in dialog
UI Fixes:
- Status label no longer wraps to new line on action bar
- Set text truncation to keep status on single line
Changed snippet "Default Format" mode from stream copy to re-encoding with
high quality settings (libx264, CRF 17, ultrafast preset). Stream copy
cannot provide precise durations as it can only cut at keyframe boundaries.
Both snippet modes now output MP4 and re-encode. The difference is quality:
- High Quality mode: CRF 17, ultrafast preset
- Conversion Settings mode: Uses configured output settings
Updated UI labels to reflect "Snippet Quality" instead of output format.

Reverts the problematic -accurate_seek and -to flags that caused wildly incorrect durations (9:40 instead of 10s). Returns to the standard, reliable FFmpeg pattern for stream copy:
ffmpeg -ss START -i input -t DURATION -c copy output
This places -ss before -i for fast keyframe seeking and uses -t for duration (not -to which is an absolute timestamp causing incorrect extraction). Should now correctly extract the configured snippet length centered on video midpoint.

Improves snippet timing accuracy for Default Format mode by:
- Adding -accurate_seek flag for precise keyframe seeking
- Changing from -t (duration) to -to (end time) for better accuracy
- Adding -avoid_negative_ts make_zero to fix timestamp issues with problematic containers like WMV
This should resolve issues where snippets were 1:20 or 0:21 instead of the configured length (e.g., 10s). Stream copy still uses keyframe-level precision but should now be much closer to target duration.

Changes multi-video drag-and-drop behavior to load videos into memory instead of automatically adding them to conversion queue. This allows users to:
- Adjust conversion settings before queuing
- Generate snippets instead of converting
- Navigate through videos before deciding to convert
Creates new loadMultipleVideos() function that loads all videos into loadedVideos array and shows informative dialog. Users can now use Convert or Snippet buttons to manually process videos as needed.

Updates snippet conversion mode to use configured video/audio codecs, presets, CRF, and bitrates from the Convert tab instead of hardcoded h264/AAC. Output extension now matches selected format (e.g., .mkv, .webm, .mp4). This allows true comparison between source format snippets and conversion preview snippets using user's exact conversion settings.

Implements configurable snippet output mode with two options:
1. Source Format (default): Uses stream copy to preserve exact video/audio quality with source container format. Duration uses keyframe-level precision (may not be frame-perfect).
2. Conversion Format: Re-encodes to h264/AAC MP4 with frame-perfect duration control.
Adds checkbox control in snippet settings UI. Users can now compare source format snippets for merge testing and conversion format snippets for output preview.

Changes snippet generation to always output .mp4 files instead of preserving source extension. This fixes duration accuracy issues caused by container/codec mismatch (e.g., h264 video in .wmv container). MP4 is the proper container for h264-encoded video and ensures FFmpeg respects the -t duration parameter correctly.

- Adds job to queue without starting
- Allows queuing multiple jobs
- Shows "Thumbnail job added to queue!" message
Implementation:
- Refactored job creation into createThumbJob() helper function
- Both buttons use same job creation logic
- Generate Now auto-starts queue if not running
- Follows same pattern as convert module
Benefits:
- Immediate generation when queue is idle
- Queue multiple jobs without starting

Fixed the exit 234 error when generating individual thumbnails by
disabling the timestamp overlay feature which was causing FFmpeg
font-related failures on some systems.
Changes:
- ShowTimestamp: false (was true)
- ShowMetadata: only true for contact sheets (was always true)
The timestamp overlay was causing issues because:
1. DejaVu Sans Mono font might not be available on all systems
2. FFmpeg exits with code 234 when drawtext filter fails
3. Individual thumbnails don't need timestamp overlays anyway
Contact sheets still get metadata headers, which is the main use case
for showing video information on thumbnails.
