## v0.1.0-dev22 (January 2026)

### 🎉 Major Features

#### Automatic GPU Detection for Hardware Encoding
- **Auto-detect GPU vendor** (NVIDIA/AMD/Intel) via system info detection
- **Automatic hardware encoder selection** when hardware acceleration set to "auto"
- **Resolves to appropriate encoder**: nvenc for NVIDIA, amf for AMD, qsv for Intel
- **Fallback to software encoding** if no compatible GPU detected
- **Cross-platform detection**: nvidia-smi, lspci, wmic, system_profiler

#### SVT-AV1 Encoding Performance
- **Proper AV1 codec support** with hardware (av1_nvenc, av1_qsv, av1_amf) and software (libsvtav1) encoders
- **SVT-AV1 speed preset mapping** (0-13 scale) for encoder performance tuning
- **Prevents 80+ hour encodes** by applying appropriate speed presets
- **ultrafast preset** → ~10-15 hours instead of 80+ hours for typical 1080p encodes
- **CRF quality control** for AV1 encoding

#### UI/UX Improvements
- **Fluid UI splitter** - removed rigid minimum size constraints for smoother resizing
- **Format selector widget** - proper dropdown for container format selection
- **Semantic color system** - ColoredSelect ONLY for format/codec navigation (not rainbow everywhere)
- **Format colors**: MKV=teal, MP4=blue, MOV=indigo
- **Codec colors**: AV1=emerald, H.265=lime, H.264=sky, AAC=purple, Opus=violet

### 🔧 Technical Improvements

#### Hardware Encoding
- **GPUVendor() method** in sysinfo package for GPU vendor identification
- **Automatic encoder resolution** based on detected hardware
- **Better hardware encoder fallback** logic

#### Platform Support
- **Windows FFmpeg popup suppression** - proper build tags on exec_windows.go/exec_unix.go

#### Code Quality
- **Queue system type consistency** - standardized JobType constants (JobTypeFilter)
- **Fixed forward declarations** for updateDVDOptions and buildCommandPreview
- **Removed incomplete formatBackground** section with TODO for future implementation
- **Git remote correction** - restored git.leaktechnologies.dev repository URL

### 🐛 Bug Fixes

#### Encoding

- **Added missing preset mapping** for libsvtav1 encoder
- **Proper CRF handling** for AV1 codec

#### UI
- **Fixed dropdown reversion** - removed rainbow colors from non-codec dropdowns
