- * Provides helpers for:
- * - Surface/Decoder management for video rendering
- * - Video size and FPS monitoring
+ * Acts as a thin front-end over [VideoDecoderController] (decoder lifecycle, bootstrap
+ * cache, error detection) and [PersistentVideoRenderer] (EGL / surface management).
+ *
+ * The facade owns the session lifecycle mutex and coordinates surface attach/detach
+ * with decoder creation. It also publishes video size / FPS to listeners.
+ *
+ * Error recovery:
+ * - When the local decoder cannot handle the video resolution (e.g. MTK AVC caps at
+ *   2048 but scrcpy sends 2400), the facade can automatically restart the session with
+ *   a lower `max_size` (controlled by the "downsize on decode error" app setting).
+ * - When the decoder enters an unrecoverable error state at runtime (e.g. MTK OMX
+ *   buffer conflict after rotation), the facade restarts the session.
