Supplying Jellyfin with media from network share and possible transcoding

[TheDreadPirate]

1. Any network storage needs to be mounted to the OS of whatever is running Jellyfin. Then you provide that mounted path to Jellyfin. It does not add any additional lag (as long as the NAS is on the same LAN).
2. Depends on the media codecs and what the client supports.
3. If you're going to spend money on a GPU, get an Intel Arc A310 or A380 GPU. Much better modern codec support, cheap, plentiful, also has half height SFF form factors.
