[expo-video] Custom cache key support

Hanna Becker

I'm streaming videos from S3 using signed urls that expire after 1 hour. So after 1h the client would refetch the same video, as the previous signed url is not accessible any longer, which could be avoided, if I could use the S3 key or base url as a cache key instead of the full url.

I recently had to write up a custom video caching layer that uses the file system to cache items and dynamically loads the URI, setting it to a cached version or a presigned URL, works well with preloading too. Having cache key support would definitely help as it will avoid applications that use videos in this manner from needing to fragment and abstract their own video-specific caching layer.
