#### Using Local Media Files
The `end2end.py` script supports local media files (audio, video, image) via CLI arguments:

```bash
# Use single local media files
python end2end.py --query-type use_image --image-path /path/to/image.jpg
python end2end.py --query-type use_video --video-path /path/to/video.mp4
python end2end.py --query-type use_audio --audio-path /path/to/audio.wav

# Combine multiple local media files
python end2end.py --query-type mixed_modalities \
    --video-path /path/to/video.mp4 \
    --image-path /path/to/image.jpg \
    --audio-path /path/to/audio.wav

# Use audio from video file
python end2end.py --query-type use_audio_in_video --video-path /path/to/video.mp4

```

If media file paths are not provided, the script will use default assets. Supported query types:
- `use_image`: Image input only
- `use_video`: Video input only
- `use_audio`: Audio input only
- `mixed_modalities`: Audio + image + video
- `use_audio_in_video`: Extract audio from video
- `text`: Text-only query
