# yt-dlp — Video Downloading
## What It Is
`yt-dlp` is a feature-rich command-line video downloader, forked from youtube-dl with active maintenance and significantly better performance. It supports YouTube, Twitch, and hundreds of other sites.
---
## Installation
### Fedora
```bash
sudo dnf install yt-dlp
# or latest via pip:
sudo pip install yt-dlp --break-system-packages
```
### Update
```bash
sudo pip install -U yt-dlp --break-system-packages
# or if installed as standalone binary:
yt-dlp -U
```
Keep it current — YouTube pushes extractor changes frequently and old versions break.
---
## Basic Usage
```bash
# Download a single video (best quality)
yt-dlp https://www.youtube.com/watch?v=VIDEO_ID
# Download to a specific directory with title as filename
yt-dlp -o "/path/to/output/%(title)s.%(ext)s" URL
```
---
## Plex-Optimized Download
Download best quality and auto-convert to HEVC for Apple TV direct play:
```bash
yt-dlp URL
```
That's it — if your config is set up correctly (see Config File section below). The config handles format selection, output path, subtitles, and automatic AV1/VP9 → HEVC conversion.
> [!note] `bestvideo[ext=mp4]` caps at 1080p because YouTube only serves H.264 up to 1080p. Use `bestvideo+bestaudio` to get true 4K, then let the post-download hook convert AV1/VP9 to HEVC. See [Plex 4K Codec Compatibility](../../04-streaming/plex/plex-4k-codec-compatibility.md) for the full setup.
---
## Playlists and Channels
```bash
# Download a full playlist
yt-dlp -o "%(playlist_index)s - %(title)s.%(ext)s" PLAYLIST_URL
# Download only videos not already present
yt-dlp --download-archive archive.txt PLAYLIST_URL
```
`--download-archive` maintains a file of completed video IDs — re-running the command skips already-downloaded videos automatically.
---
## Format Selection
```bash
# List all available formats for a video
yt-dlp --list-formats URL
# Download best video + best audio, merge to mp4
yt-dlp -f 'bestvideo+bestaudio' --merge-output-format mp4 URL
# Download audio only (MP3)
yt-dlp -x --audio-format mp3 URL
```
---
## Config File
Persist your preferred flags so you don't repeat them every command:
```bash
mkdir -p ~/.config/yt-dlp
cat > ~/.config/yt-dlp/config << 'EOF'
--remote-components ejs:github
--format bestvideo+bestaudio
--merge-output-format mp4
--output /plex/plex/%(title)s.%(ext)s
--write-auto-subs
--embed-subs
--exec /usr/local/bin/yt-dlp-hevc-convert.sh {}
EOF
```
After this, a bare `yt-dlp URL` downloads best quality, saves to `/plex/plex/`, embeds subtitles, and auto-converts AV1/VP9 to HEVC. See [Plex 4K Codec Compatibility](../../04-streaming/plex/plex-4k-codec-compatibility.md) for the conversion hook setup.
---
## Running Long Downloads in the Background
For large downloads or playlists, run inside `screen` or `tmux` so they survive SSH disconnects:
```bash
screen -dmS yt-download bash -c \
"yt-dlp -o '/plex/plex/%(title)s.%(ext)s' PLAYLIST_URL 2>&1 | tee ~/yt-download.log"
# Check progress
screen -r yt-download
# or
tail -f ~/yt-download.log
```
