  • I am currently running Jellyfin on Btrfs and there is quite a performance impact due to CoW. If 2 clients decide to browse the libraries, both clients grind to a near standstill with regards to being able to see things.

    CoW is not recommended for databases, all DB servers advise for turning it off for the actual database. You’ll run into the same issue with a dedicated database if you leave CoW on I guess. You could also disable CoW for jellyfin’s database right now and performance should increase.

    I also follow the progress of a dedicated DB, but on the other hand I don’t know how much sense it makes architecturally. The likeliness that you have multiple jellyfin server instances access the same database is low - after all, there is info very specific to the server in there like the file path. Just migration is already not easy, how likely is sharing the database live? And if each database is specific to an instance - why not use SQLite (like it’s done right now) and allow for more specific parameter tuning, like used memory and the like?





  • They aren’t really designed to stop people from breaking in but rather to stop intrusive people that you talk to first before deciding to not let them in. With the chain, you can open the door a bit without allowing the person outside to force himself in without too much force, e.g. by blocking the door with your foot as the door can only be opened fully after closing it.

    Advanced versions exist where if you put strain on the chain (mostly trying to push the door open from the outside) an alarm goes off.







  • Very first paragraph:

    The first really good video codec was MPEG-4 H.264. I remember in 2001 my housemate watching a movie on his telly — playing off a CD-R. A whole movie crammed onto a CD, encoded with DivX!

    DivX was an implementation of MPEG-4 ASP, also known as H.263. H.264 came much later with x264 being the most well-known encoder (hence its name).

    ASP in my opinion never got the biggest chance to shine with regards to quality because the target medium was often the CD which limited file size to 700MB, and once DVDs became an option, people went back to MPEG-2 because that’s what the players were all compatible with. Sometimes even (S)VCDs were used still. Standalone players with ASP support came rather later.
