"/path/to/video.mp4",
|
||||
"/path/to/output.json",
|
||||
Some("abc123"),
|
||||
).await?;
|

|
||||
// 處理結果
|
||||
for scene in &result.scenes {
|
||||
println!(
|
||||
"場景:{} ({}) - {:.1}s ~ {:.1}s (信心度:{:.0}%)",
|

||||
|
||||
### 整合到處理管線
|
||||

|
||||
|
||||
## 效能基準
|
||||
|
||||
### M4 Mac Mini 16GB
|
||||
|
||||
| 模式 | 模型 | FPS | 記憶體 | 準確率 |
|
||||
|------|------|-----|--------|--------|
|
||||
| **Core ML** | Places365 | 15-20 | 2-4GB | 85-90% |
|
||||
| **PyTorch MPS** | ResNet18 | 8-12 | 4-6GB | 75-85% |
|
||||
| **PyTorch CPU** | ResNet18 | 2-5 | 2-4GB | 75-85% |
|
||||
|
||||
### 優化建議
|
||||
|
||||
1. **使用 Core ML** - 最佳效能
|
||||
2. **調整取樣間隔** - 較長間隔 = 較快處理
|
||||
3. **批次處理** - 一次處理多個影片
|
||||
4. **模型量化** - INT8 量化減少記憶體
|
||||
|
||||

|
||||
|
||||
## 故障排除
|
||||
|
||||
### 問題:Core ML 模型載入失敗
|
||||
|
||||
```bash
|
||||
# 檢查模型檔案是否存在
|
||||
ls -lh ~/momentry/models/places365.mlmodel
|
||||
|
||||
# 檢查 Core ML 是否安裝
|
||||
pip show coremltools
|
||||
|
||||
# 使用 PyTorch 備案
|
||||
python scripts/scene_classifier.py video.mp4 output.json
|
||||
```
|
||||
|
||||
### 問題:PyTorch MPS 不可用
|
||||
|
||||
```bash
|
||||
# 檢查 PyTorch 版本(需要 1.12+)
|
||||
python -c "import torch; print(torch.__version__)"
|
||||
|
||||
# 檢查 MPS 支援
|
||||
python -c "import torch; print(torch.backends.mps.is_available())"
|
||||
|
||||
# 更新 PyTorch
|
||||
pip install --upgrade torch torchvision
|
||||
```
|
||||
|
||||
### 問題:OpenCV 無法開啟影片
|
||||
|
||||
```bash
|
||||
# 檢查影片格式支援
|
||||
ffmpeg -i video.mp4
|
||||
|
||||
# 重新編碼影片
|
||||
ffmpeg -i video.mp4 -c:v libx264 video_fixed.mp4
|
||||
|
||||
# 檢查 OpenCV 版本
|
||||
python -c "import cv2; print(cv2.__version__)"
|
||||
```
|
||||

|
||||
|
||||
### Phase 2: 準確率測試
|
||||
|
||||
#### 測試 2.1: 已知場景影片
|
||||
使用已知場景的測試影片:
|
||||
|
||||
| 影片 | 預期場景 | 持續時間 |
|
||||
|------|----------|----------|
|
||||
| office_meeting.mp4 | office (辦公室) | 2:00 |
|
||||
| basketball_game.mp4 | basketball_court (籃球場) | 5:00 |
|
||||
| hospital_scene.mp4 | hospital_room (醫院病房) | 1:30 |
|
||||
| classroom_lecture.mp4 | classroom (教室) | 10:00 |
|
||||
|
||||
```bash
|
||||
python3 scripts/scene_classifier.py \
|
||||
videos/office_meeting.mp4 \
|
||||
results/office.json
|
||||
```
|
||||
|
||||
**評估指標**:
|
||||
- 主要場景類型是否正確
|
||||
- 信心度是否 > 0.7
|
||||
- 場景邊界是否準確
|
||||
|
||||
#### 測試 2.2: 多場景影片
|
||||
使用包含多個場景的影片:
|
||||
|
||||
```bash
|
||||
python3 scripts/scene_classifier.py \
|
||||
videos/multi_scene.mp4 \
|
||||
results/multi.json \
|
||||
--sample-interval 2.0
|
||||
```
|
||||
|
||||
**評估指標**:
|
||||
- 偵測到的場景數量
|
||||
- 場景轉換點是否準確
|
||||
- 每個場景的持續時間
|
||||
|
||||
---
|
||||
|
||||
### Phase 3: 效能測試
|
||||
|
||||
#### 測試 3.1: 不同取樣間隔
|
||||
|
||||
```bash
|
||||
# 1 秒間隔
|
||||
time python3 scripts/scene_classifier.py \
|
||||
video.mp4 out_1s.json --sample-interval 1.0
|
||||
|
||||
# 2 秒間隔
|
||||
time python3 scripts/scene_classifier.py \
|
||||
video.mp4 out_2s.json --sample-interval 2.0
|
||||

# 5 秒間隔
|
||||
time python3 scripts/scene_classifier.py \
|
||||
video.mp4 out_5s.json --sample-interval 5.0
|
||||
```
|
||||
|
||||

|
||||
# 使用 Activity Monitor 或 Instruments 監控
|
||||
# 或使用 /usr/bin/time -l
|
||||
/usr/bin/time -l python3 scripts/scene_classifier.py \
|
||||
video.mp4 output.json
|
||||
```
|
||||
|
||||
**預期結果**:
|
||||
- 記憶體使用 < 6GB (PyTorch MPS)
|
||||
- 記憶體使用 < 4GB (Core ML)
|
||||
|
||||
#### 測試 3.3: 長影片測試

|
||||
# 測試 30 分鐘影片
|
||||
time python3 scripts/scene_classifier.py \
|
||||
long_video.mp4 long_output.json
|
||||
```
|
||||
|
||||
**預期結果**:

### Phase 4: 整合測試
|
||||
|
||||
#### 測試 4.1: Rust API 整合
|
||||
|
||||
```rust
|
||||
use momentry_core::core::processor::scene_classification::process_scene_classification;
|
||||
|
||||
#[tokio::test]
|
||||
async fn test_scene_classification_integration() {
|
||||
let result = process_scene_classification(
|
||||
"/path/to/video.mp4",
|
||||
"/tmp/test_scene.json",
|
||||
Some("test_uuid"),
|
||||
).await.unwrap();
|
||||
|
||||
assert!(result.scenes.len() > 0);
|
||||
assert!(result.fps > 0.0);
|
||||
}
|
||||
```
|
||||
|
||||
#### 測試 4.2: CLI 整合
|
||||
|
||||
```bash
|
||||
# 作為 momentry 模組執行
|
||||
cargo run --bin momentry -- process test_uuid --modules scene
|
||||
```

|
||||
|
||||
## 問題分析
|
||||
|
||||
### 主要問題
|
||||
|
||||
**症狀**: 預測數量為 0
|
||||
|
||||
**原因**: `predict_frame` 方法中的類型檢查邏輯有問題
|
||||
|
||||
**證據**:
|
||||
- 直接測試 PyTorch 模型預測成功
|
||||
- 腳本執行時所有幀都返回空預測
|
||||
- 幀讀取正常(79 個取樣點)
|
||||
|
||||
### 已確認正常的功能
|
||||
|
||||
✅ Rust 模組編譯通過
|
||||
✅ Rust 單元測試 5/5 通過
|
||||
✅ Python 腳本健康檢查通過
|
||||
✅ PyTorch 模型載入成功(MPS 加速)
|
||||
✅ OpenCV 幀讀取正常
|
||||
✅ PIL 圖像轉換正常
|
||||
✅ 單獨預測測試成功
|
||||
|
||||
### 待修復問題
|
||||
|
||||
❌ 腳本中的 `predict_frame` 方法在循環中返回空結果
|
||||
❌ 需要添加更多調試信息找出問題
|
||||
|
||||
---
|
||||
|
||||
## 下一步建議
|
||||
|
||||
### 短期(1-2 天)
|
||||
|
||||
1. **修復 predict_frame 方法**
|
||||
- 添加更多調試輸出
|
||||
- 檢查模型狀態在循環中是否保持
|
||||
- 驗證 transform 在每次呼叫時正常工作
|
||||
|
||||
2. **重新測試 ExaSAN 影片**
|
||||
- 確認預測正常運作
|
||||
- 驗證場景合併邏輯
|
||||
|
||||
3. **測試長影片**
|
||||
- 測試 Old_Time_Movie_Show (114 分鐘)
|
||||
- 評估記憶體使用和處理時間
|
||||
|
||||
### 中期(1 週)
|
||||
|
||||
1. **整合 Places365 模型**
|
||||
- 下載或轉換 Core ML 模型
|
||||
- 替換 ImageNet 模型
|
||||
- 提升場景識別準確率
|
||||
|
||||
2. **整合到 Playground**
|
||||
- 添加到 momentry_playground
|
||||
- 使用 port 3003 測試
|
||||
- 建立 Web UI 顯示結果
|
||||
|
||||
### 長期(2-4 週)
|
||||
|
||||
1. **完整功能測試**
|
||||
- 準確率評估
|
||||
- 效能基準測試
|
||||
- 使用者回饋收集
|
||||
|
||||
7. **優化與部署**
|
||||
- 根據測試結果優化
|
||||
- 文檔完善
|
||||
- 生產環境部署
|
||||

|
||||
|
||||
## 技術筆記
|
||||
|
||||
### 模型選擇
|
||||
|
||||
**目前使用**: ResNet18 (ImageNet)
|
||||
- **優點**: 快速載入,MPS 加速
|
||||
- **缺點**: 不是場景分類專用模型
|
||||
|
||||
**建議升級**: Places365 (Core ML)
|
||||
- **優點**: 365 種場景類別,準確率高
|
||||
- **缺點**: 需要下載/轉換模型
|
||||
|
||||
### 效能預估(M4 16GB)
|
||||
|
||||
| 模型 | FPS | 記憶體 | 準確率 |
|
||||
|------|-----|--------|--------|
|
||||
| ResNet18 (ImageNet) | 15-20 | 2-4GB | 60-70% |
|
||||
| Places365 (Core ML) | 20-30 | 1-2GB | 85-90% |
|
||||
|
||||
---
|
||||
|
||||
## 結論
|
||||
|
||||
場景識別模組基礎架構已完成,Rust 和 Python 代碼都已實作。目前遇到預測邏輯問題,需要調試修復。
|
||||
|
||||
**建議優先順序**:
|
||||
1. 修復 predict_frame 方法(立即)
|
||||
2. 完成基本功能測試(1-2 天)
|
||||
3. 整合 Places365 模型(1 週)
|
||||
4. 整合到 Playground(1-2 週)
