Why TXXX Downloader

为什么选择TXXX Downloader

TXXX pages can expose different playback formats depending on the source and player state. Generic download tools often fail because they assume a single direct file instead of detecting the active stream after playback starts.
TXXX Downloader is built to make that process simpler. Open the page, let the extension detect the media, choose the available quality, and save the result as MP4 from inside the browser.
TXXX页面会根据来源和播放器状态暴露不同的播放格式。通用下载工具经常失效，因为它们默认存在单个直接文件，而不会在播放启动后检测活动流。
TXXX Downloader就是为了简化这个流程而打造的：打开页面，让扩展检测媒体资源，选择可用画质，直接在浏览器内将结果保存为MP4即可。
