[!WARNING] MissAV has a cloudflare challenge page which can't be bypassed using puppeteer/playwright, so you need to download the html page manually (no js and css needed, only html), then pass the local file path to extract m3u8 source. fast-dirpy download --json '[{"url": "missav:/home/xxx/Downloads/xxx.html", "path": "./msav-test.mp4"}]'

And this method is unstable, sometimes you'll get http 429.

• missav

[!WARNING] XHamster requests are mostly failed, so above v1.0.2, it also provides manual link extract method. download the html page(no js and css needed, only html), then pass the local file path to extract m3u8 source. fast-dirpy download --json '[{"url": "xhamster:/home/xxx/Downloads/xxx.html", "path": "./xhamster-test.mp4"}]'

• xhamster (m3u8, if error, manually download html page.)

And .m3u8 videos.

Usage

Config file

Important

fast-dirpy.config can be fast-dirpy.config.['ts', 'mts', 'cts', 'js', 'mjs', 'cjs', 'json']

You can create a fast-dirpy.config file in your library root or same location in command line.

import { defineConfig } from 'fast-dirpy'

export default defineConfig({
  proxy: {
    protocol: 'http',
    host: '127.0.0.1',
    port: 7890,
  },
  timeout: 20000, // request timeout: 20s
  puppeteer: {
    // Path to Chrome. Please notice that you must give the inner unix executable file path in macOS.
    // /Applications/Google Chrome.app will not work.
    executablePath: "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
    headless: true
  }
}

Use in command line

Important

Some website listed in Supported Websites requires Google Chrome installed for Puppeteer use. You have to use a config file or give parameter of puppeteer executable path.

Get Direct Link

# get video direct link
# Proxy:
#   -H, --proxyHost: proxy host
#   -P, --proxyPort: proxy port
#   -c, --config: Specified external config file.
#       e.g.: fast-dirpy get https://xxx -c ~/Downloads/fast-dirpy.config.json
#   --chromePath: Path to your Google Chrome browser.
fast-dirpy get https://www.youtube.com/watch?v=6c28qWDMPBA -H 127.0.0.1 -P 7890

# Bilibili source doesn't need any proxy, so it's disabled by default.
fast-dirpy get https://www.bilibili.com/video/BV1TSPeeGE35

if you have set your proxy config in fast-dirpy.config.ts, you can omit proxy parameters:

fast-dirpy get https\://www.youtube.com/watch\?v\=6c28qWDMPBA

Download Video

Important

1. Some website listed in Supported Websites requires Google Chrome installed for Puppeteer use. You have to use a config file or give parameter of puppeteer executable path.
2. You can download multiple videos in parallel at version v1.0.0 and above.

# Proxy:
#  -H, --proxyHost: proxy host.
#  -P, --proxyPort: proxy port.
#  -c, --config: Specified external config file.
#       e.g.: fast-dirpy get https://xxx -c ~/Downloads/fast-dirpy.config.json
#  --chromePath: Path to your Google Chrome browser.

fast-dirpy download --json '[{"url": "https://www.bilibili.com/video/BV1uEAWzuEHC","path": "./cmd-test.mp4"}]' -H 127.0.0.1 -P 7890

fast-dirpy download --json-file ./test/params.json -H 127.0.0.1 -P 7890

if you have set your proxy config in fast-dirpy.config.ts, you can omit proxy parameters:

fast-dirpy download --json-file ./test/params.json

fast-dirpy download --json '[{"url": "https://www.bilibili.com/video/BV1uEAWzuEHC","path": "./cmd-test.mp4"}]'
