Summary of Changes

Hello @bebechien, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the video-understanding.ipynb notebook to retrieve its sample video from a GitHub repository instead of a Google Cloud Storage bucket. This change aims to improve the reliability and accessibility of the video resource used in the notebook, along with updating the recorded execution outputs to match the new source.

Highlights

• Video URL Migration: The video download URL in the video-understanding.ipynb notebook has been migrated from a Google Cloud Storage bucket to a GitHub raw content link, ensuring a more consistent and accessible source for the sample video.
• Notebook Output Updates: Associated execution counts and output logs within the notebook were refreshed to reflect the new video source and the updated execution environment.

Changelog

• docs/capabilities/vision/video-understanding.ipynb
  • Updated the video download URL to point to a GitHub raw content link.
  • Adjusted the execution count for a code cell.
  • Refreshed the wget and ffmpeg command output logs to reflect the new download source and execution environment.

Code Review

The pull request successfully migrates the video download URL from Google Cloud Storage to a GitHub raw content URL, aligning with the pull request's objective. The changes in the notebook's output reflect this new source and the execution environment. While the migration to GitHub is complete, it's worth considering the long-term stability and performance implications of serving large assets directly from raw GitHub content URLs for tutorials.

[gemini-code-assist]

The video asset is now sourced from a raw GitHub content URL. While this works, raw GitHub URLs are generally not designed for high-availability or high-performance content delivery and can sometimes be subject to rate limits or changes in repository structure that could break the link. For a tutorial that needs to be consistently runnable, using a more stable content delivery mechanism (like a dedicated CDN or object storage) might be more robust in the long run. However, given the PR's explicit goal to migrate to GitHub, this is noted as a potential point of fragility rather than a direct issue with the current implementation.

That's our team's public-facing bucket, can you update to use that instead of a GitHub link?
