How To Download Youtube Videos In Java
java-youtube-downloader
Unproblematic java parser for retrieving youtube video metadata.
Library is not stable, because Youtube frequently changes web structure of its pages. I don't use this library regularly to discover the errors. Thats why errors are stock-still as soon as someone finds information technology and opens an outcome. Feel gratis to report an fault or sumbit a PR.
Warning: Youtube API does not back up a video download. In fact, information technology is prohibited - Terms of Service - 2. Prohibitions.
Alarm: Downloading videos may violate copyrights!
This project is simply for educational purposes. I urge not to utilise this project to violate any laws.
Usage
Configuration
// init downloader with default config YoutubeDownloader downloader = new YoutubeDownloader(); // or with custom config Config config = new Config.Builder() .executorService(executorService) // for async requests, default Executors.newCachedThreadPool() .maxRetries(1) // retry on failure, default 0 .header("Take-language", "en-US,en;") // extra request header .proxy("192.168.0.1", 2005) .proxyCredentialsManager(proxyCredentials) // default ProxyCredentialsImpl .proxy("192.168.0.1", 2005, "login", "pass") .build(); YoutubeDownloader downloader = new YoutubeDownloader(config); // or configure after init Config config = downloader.getConfig(); config.setMaxRetries(0); Asking
// each asking accepts optional params that will override global configuration Request request = new Request(...) .maxRetries(...) .proxy(...) .header(...) .callback(...) // add callback for async processing .async(); // brand request async Response
