+description: Safari iOS 16 inline preview can stay white when multiple simple-vue-camera instances mount and playback readiness is assumed too early
+type: project
+---
+
+In `HomeView.vue`, Safari on iOS 16.x can show a white in-page camera preview when more than one `simple-vue-camera` instance is mounted for responsive layouts and the app treats `camera.start()` as sufficient proof that the preview is rendering.
+
+**Why:** `simple-vue-camera` uses a hard-coded `id="video"` internally and does not explicitly call `video.play()` during `start()`. On mobile/xs, mounting both desktop and mobile camera components at once creates a fragile setup for Safari, where the active preview can remain white even though permission and stream startup succeeded.
+
+**How to apply:** Keep only the active responsive camera instance mounted in `HomeView.vue`, and after `camera.start()` explicitly prepare/check the underlying video element (`playsinline`, `muted`, `play()`, non-zero dimensions, ready state). If the preview still does not become render-ready, remount once and then fall back to native capture.
