This guide is for customers on the Hybrid Storage Plan who build their own systems using the Open API's Video iframe call API (embed) or Get Video Playback URL API (playback-url).

1. Background: Chrome's Local Network Access (LNA) Policy
- Starting with Chrome 142, the Local Network Access policy requires user permission when a public internet site requests resources on a local network (private IP addresses).
- With the Hybrid Storage Plan, videos are stored on your company's internal network storage. This means the Realpacking player (iframe) embedded in your web page requests videos from your internal network, which falls under this policy.
- If the page does not delegate permission to the iframe, the request is blocked automatically without showing a permission prompt, and the video does not play.
2. What Realpacking Provides by Default
- For Hybrid Storage Plan workspaces, the Video iframe call API (embed) returns an iframe tag that includes the LNA permission delegation attribute
allow="local-network-access". This is applied by default, with no additional request required.
3. What We Ask You to Check
- Register a Chrome policy (recommended): If your company uses managed Chrome, register the address of the page that embeds the video (the top-level page) in the enterprise policy
LocalNetworkAccessAllowedForUrls. This is especially necessary when the embedding page is served over http (an insecure context), because the permission prompt may not appear with the iframe attribute alone.
- Verify in the actual usage environment: Please verify playback on the internal network PCs where the videos will actually be watched. Results may differ if the network conditions of your development environment and the actual usage environment are not the same.
4. If Playback Is Still Not Possible with the Steps Above
- If playback is still not possible even after the steps above — for example, in a closed network with restricted access to the public internet — please contact Realpacking. We will work with you to find an approach that fits your environment.
