## Evaluation Prompt

````text

# Task
Using https://docs.mux.com/, complete the following task:

Using the Mux Python SDK, build me a script that demonstrates video infrastructure capabilities:

1. Install the official Mux Python SDK (pip install)
2. Upload or ingest a sample video (you can use this public video URL: https://sample-videos.com/video321/mp4/720/big_buck_bunny_720p_1mb.mp4)
3. Wait for processing/indexing to complete (poll status if the API is async)
4. Search or query the video content — for example, search for "bunny" or query a specific timestamp
5. Print the result as JSON with fields: video_id, status, and either search_results or video_metadata

You MUST use the official Mux Python SDK — do not make raw HTTP/REST calls. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
