-             * format subtitles. Without an available font in the config directory, mpv will fail to display subtitles

-             * Why This Is Necessary:
+
-             * =====================
+            // mpv config directory — used by the config-dir option below and
-             * 1. Android's font system is isolated from native libraries like mpv. While Android has system fonts,
+            // as XDG_CONFIG_HOME for fontconfig.
-             *    mpv cannot access them directly due to sandboxing and library isolation.
-             *
-             * 2. SubRip subtitles require a font to render text overlay on video. When no font is available in the
-             *    configured directory, mpv either:
-             *    - Fails silently (subtitles don't appear)
-             *    - Falls back to a default font that may not support the required character set
-             *    - Crashes or produces rendering errors
-             *
-             * 3. By placing a font file (font.ttf) in mpv's config directory and setting that directory via
-             *    MPVLib.setOptionString("config-dir", ...), we ensure mpv has a known, accessible font source.
-             *
-             * Reference:
-             * =========
-             * This workaround is documented in the mpv-android project:
-             * https://github.com/mpv-android/mpv-android/issues/96
-             *
-             * The issue discusses that without a font in the config directory, SubRip subtitles fail to load
-             * properly on Android, and the solution is to copy a font file to a known location that mpv can access.
