TL;DR: Stop running a Jellyfin server. MPV can directly play anything from your NAS, stream YouTube ad-free, handle literally every codec, and is infinitely customizable. It’s like vim for video.

Why I ditched my Jellyfin setup

I used to run Jellyfin on my NAS. Transcoding, web interface, the works. Then I realized… why am I running a whole server stack when MPV can just directly play files from my NAS with zero setup?

What MPV Actually Is

MPV is a command-line video player that plays literally everything. But it’s way more than that - it’s a video engine you can build workflows around.

The Basics That Blow Minds

Direct NAS streaming (zero server needed):

mpv smb://192.168.1.100/media/movies/whatever.mkv
mpv nfs://nas.local/shows/season1/*

No transcoding. No server. No web interface overhead. Just direct file access with perfect quality and zero latency.

YouTube (and 1000+ sites) with ZERO ads:

brew install yt-dlp
mpv "https://youtube.com/watch?v..."

That’s it. Ad-free YouTube in your video player with all your custom keybinds. Works with Twitch, Vimeo, Twitter, Reddit, literally hundreds of sites via yt-dlp.

Play entire directories:

mpv /Volumes/NAS/shows/BreakingBad/Season1/*

Boom. Instant binge session. Space bar skips to next episode. No library scanning, no metadata scraping, just files.

Workflows That Changed My Life

1. The “Watch Anywhere” Setup

Mount your NAS shares in Finder (or /etc/fstab for auto-mount). Now MPV treats your entire media library like local files. Add this to your shell config:

alias play="mpv"
alias tv="mpv /Volumes/NAS/shows/"
alias movies="mpv /Volumes/NAS/movies/"

2. YouTube as Your Streaming Service

alias yt="mpv"
alias ytm="mpv --no-video"  # audio only for music

Now:

• yt "youtube-url" = instant ad-free playback
• ytm "youtube-playlist" = whole playlists as audio
• Keep your YouTube history/recommendations in browser, watch in MPV

3. Picture-in-Picture for Anything

Add ontop=yes to config, resize window small = instant PiP for any video source while you work. Works with live streams, security cameras, whatever.

4. The “No Plex Shares Needed” Share

Send someone an SMB/NFS share to your media. They install MPV. They can now browse and play your media library like it’s local. No Plex accounts, no streaming limits, no transcoding quality loss.

5. Live Stream Monitoring

mpv http://192.168.1.50:8080/stream.m3u8

Home security cameras, baby monitors, anything streaming HLS/RTMP = instant monitoring with keybind controls.

Customization That Makes Jellyfin Look Basic

My Config (vim-style keybinds + YouTube controls)

Saved as ~/.config/mpv/mpv.conf:

Use with: mpv --profile=anime episode.mkv

Scripts That Make It Insane

MPV supports Lua/JS scripts. Drop them in ~/.config/mpv/scripts/ and they just work.

Must-have scripts:

1. sponsorblock - Auto-skips YouTube sponsors/intros/outros

   curl -o ~/.config/mpv/scripts/sponsorblock.lua \
     https://raw.githubusercontent.com/po5/mpv_sponsorblock/master/sponsorblock.lua
   

2. quality-menu - Change YouTube quality on the fly

3. autosubsync - Auto-fixes subtitle timing

4. playlistmanager - Visual playlist editor

5. mpv-discordRPC - Show what you’re watching on Discord

Advanced Workflows

Watch Parties (Syncplay)

Install syncplay, point it at MPV, now you and friends watch your NAS content together in perfect sync. No Plex share limits, no quality loss.

Audio Streaming

ytm "youtube-playlist-url"
# or
mpv --no-video /Volumes/NAS/music/*

No GUI needed. Terminal command plays audio, you use keybinds (k=pause, j/l=skip, etc). Or just minimize and use as background music player.

For GUI: IINA (Mac) is literally just MPV with a pretty interface and uses your MPV config.

Frame-by-Frame Analysis

Built-in keybinds (. and , in my config) step forward/back frame-by-frame. Perfect for animation analysis, sports breakdown, debugging video issues.

Automated Workflows

# Watch anything in clipboard
mpv $(pbpaste)

# Random episode
mpv "$(find /Volumes/NAS/shows -name "*.mkv" | shuf -n1)"

# Continue last watched (auto position restore)
mpv /Volumes/NAS/shows/CurrentShow/*

Why This Beats Jellyfin For Me

Pros:

• Zero server maintenance
• No transcoding = perfect quality
• Plays literally any codec without setup
• Way faster (direct file access)
• Keyboard-driven workflow
• Works offline/online seamlessly
• Infinitely scriptable
• Cross-platform (Linux/Mac/Windows)

Cons:

• No pretty web UI (I consider this a pro)
• No user management (just use OS permissions)
• No watch tracking (unless you script it)
• No mobile app (VLC on phone + SMB works though)

Who This Is For

• You’re comfortable with terminal/config files
• You want maximum quality (no transcoding ever)
• You prefer keyboard controls
• You value simplicity over features
• You already have a NAS/file server
• You want YouTube ad-free without browser extensions

Getting Started

# macOS
brew install mpv yt-dlp

# Linux
sudo apt install mpv yt-dlp

# Windows
scoop install mpv yt-dlp

Create config at:

• Mac/Linux: ~/.config/mpv/mpv.conf
• Windows: %APPDATA%/mpv/mpv.conf

Mount your NAS shares, point MPV at files. Done.

EDIT: Holy shit, didn’t expect this response. Common questions:

Q: But I need to share with family who aren’t technical A: IINA (Mac) or mpv.net (Windows) give them a normal GUI that uses MPV underneath. Or just… teach them? play movie.mkv isn’t rocket science.

Q: What about mobile? A: VLC on phone + SMB share to your NAS. Or just use MPV on desktop/laptop like a civilized person.

Q: No watch history tracking? A: save-position-on-quit=yes remembers position per file. For tracking across devices, write a simple script or just… remember what you watched?

Q: This sounds like gatekeeping A: It’s literally a config file. If you can set up Jellyfin, you can handle this.
