Furthermore, Bilibili&rsquo;s AI subtitles often use non-standard language tags (like ai-zh), which can lead to &ldquo;null&rdquo; tracks or rendering errors in older mpv kernels (like the one used in IINA).</p> <p>Thankfully, <code>yt-dlp</code> allows us to extract and download these Danmaku and AI subtitles; <code>danmaku2ass</code>(deveoped by <a href="https://github.com/m13253">@m13253</a>) provides a brilliant solution to convert XML files to ASS subtitles.</p>
