Hi,
Why does it use a separate cache for .ts files?
I added comments in Add comments to remote storage cache (b0934eb7) · Commits · Framasoft / PeerTube / documentation · GitLab
Do they answer your questions?
What is the reason for setting an expiration time on any of the cached files? Why not keep everything as long as space permits?
Maybe to prevent delete videos to still be cached?
Lives use .ts files whereas VOD videos use fragmented .mp4 files
