Feature Request: Enable Direct Playback of Recordings from S3 Storage using Scalelite

[Anand]

Problem to Solve:

With Scalelite v1.6.8 and later, recordings can now be uploaded directly to S3-compatible storage. However, Scalelite still appears to require local filesystem access for playback.
This means recordings must still be copied or synced to /var/scalelite/recordings for playback to function, defeating the purpose of fully storing recordings in S3.

This creates additional operational overhead and prevents a true object-storage-only setup.

Proposed Solution

Enable direct playback of recordings from S3 without requiring local copies. Possible approaches include:

• Allow Scalelite to generate playback URLs that point directly to S3 objects.
• Use pre-signed URLs for secure access.
• Treat S3 as a valid recording source, so recordings do not need to be downloaded to local storage.
• Update the recording manifest handling to support S3 paths.

This would allow playback to occur entirely through S3, making deployments lighter and more scalable.

Considered Alternatives

• Syncing recordings from S3 back to local storage before playback.
  Works, but removes most benefits of object storage.
• Using an NFS or distributed filesystem.
  Adds complexity and is unnecessary when S3 storage already exists.
• Custom scripts to rewrite playback URLs.
  Fragile and not maintainable long-term.

None of these provides a clean or scalable solution like native S3 playback would.

Additional Context

• This feature would significantly improve containerized and cloud-native deployments.
• It aligns with the new S3-upload support but removes the last dependency on local disks.
• If direct playback from S3 is already supported or partially available, clarification would be appreciated.
