+ ## Convert binary objects
29
+ Because the returned video will be in bytes, here is a way to extract frames and fps:
30
+ ```python
31
+ import io
32
+ import numpy as np
33
+ from PIL import Image
34
+ from datasets import load_dataset
35
+
36
+ def extract_image(image_bytes):
37
+ img = Image.open(io.BytesIO(image_bytes))
38
+ arr = np.asarray(img)
39
+ return arr
40
+
41
+ dataset = load_dataset("Vividbot/instruct500k_vi", name="all", streaming=True)
42
+
43
+ image_bytes = next(iter(dataset))["image"]
44
+ image = extract_image(image_bytes)
45
+ print(f"Image shape: {image.shape}")
46
+ ```
