from google import genai
from google.genai.types import HttpOptions, Part

client = genai.Client(http_options=HttpOptions(api_version="v1"))
model_id = "gemini-2.5-flash"

# Read local video file content
with open("test_data/describe_video_content.mp4", "rb") as fp:
    # Video source: https://storage.googleapis.com/cloud-samples-data/generative-ai/video/describe_video_content.mp4
    video_content = fp.read()

response = client.models.generate_content(
    model=model_id,
    contents=[
        Part.from_text(text="hello-world"),
        Part.from_bytes(data=video_content, mime_type="video/mp4"),
        "Write a short and engaging blog post based on this video.",
    ],
