# GPU Acceleration Implementation Steps

## Status: In Progress ✅ Started

**Hardware Confirmed:**
- 2x NVIDIA RTX 3060 (12GB each)
- NVIDIA Driver 580.76.05, CUDA 13.0
- FFmpeg 4.4.2 with NVENC support (h264_nvenc, hevc_nvenc)
- hwaccels: cuda ✅

## Completed Steps
- [x] Verified GPU/FFmpeg setup
- [x] Created config/ffmpeg.php ✅
- [x] Updated CompressVideoJob.php with NVENC ✅
- [x] Updated VideoController.php queue dispatch ✅

## Next Steps (Approved Plan)
1. ~~Verify GPU/FFmpeg readiness~~ ✅
2. ~~Create config/ffmpeg.php for global NVENC settings~~ ✅
3. ~~Update app/Jobs/CompressVideoJob.php: Switch to h264_nvenc (CRF 23, preset p4)~~ ✅
4. ~~Update app/Http/Controllers/VideoController.php: Queue dispatch tweaks~~ ✅
5. ~~Setup queue: php artisan queue:table && migrate && QUEUE_CONNECTION=database~~ ✅ (tables exist)
6. ~~Test encoding: Upload video, monitor logs/GPU util~~ → Now implementing HLS GPU playback
7. ~~Optional~~ Create GenerateHlsJob + frontend HLS.js player ✅ Planning
8. Update model/controller/views for HLS playback

## Commands to Run After Code Changes
```
php artisan config:clear
php artisan queue:table
php artisan migrate
# Edit .env: QUEUE_CONNECTION=database
php artisan queue:work --queue=video-processing --tries=3
# Test upload, tail -f storage/logs/laravel.log && watch nvidia-smi
```

## Testing
- Upload test video
- Check encoding speed (should be 5-10x faster)
- Verify quality/size
