Cookie Setup

Get Cookie from Browser

1. Login to bilibili.com
2. Press F12 → Network → Refresh page
3. Copy Cookie from request headers

Set Environment Variable

# Add to ~/.bashrc for persistence
export BILIBILI_COOKIE="SESSDATA=xxx; bili_jct=xxx; DedeUserID=xxx; DedeUserID__ckMd5=xxx"

# Or set temporarily

How It Works

Video download uses yt-dlp with Netscape-format cookie file:

1. Parses BILIBILI_COOKIE environment variable
2. Creates temporary Netscape-format cookie file
3. Runs yt-dlp --cookies <file> -f <format> -o <output>
4. Cleans up temporary file
