Scegli un tipo di superficie per PlayerView
L'attributo surface_type di PlayerView consente di impostare il tipo di
superficie utilizzata per la riproduzione video. I valori consentiti sono:
spherical_gl_surface_view (SphericalGLSurfaceView) - per la riproduzione
di video sferici
video_decoder_gl_surface_view (VideoDecoderGLSurfaceView) - rendering
video utilizzando i renderer delle estensioni
none, che serve solo per la riproduzione audio e deve essere utilizzato per evitare di dover creare una superficie, perché può essere costoso.
Se la visualizzazione è per la normale riproduzione video, devono essere utilizzati surface_view o texture_view. SurfaceView offre una serie di vantaggi rispetto a
TextureView per la riproduzione video:
Maggiore precisione nella sincronizzazione dei frame, per una riproduzione video più fluida.
Supporto per l'output video HDR di qualità superiore sui dispositivi idonei.
Supporto dell'output protetto durante la riproduzione di contenuti protetti da DRM.
La possibilità di eseguire il rendering dei contenuti video alla risoluzione completa del display sui
dispositivi Android TV che eseguono l'upscaling del livello UI.
Pertanto, SurfaceView dovrebbe essere preferito a TextureView, se possibile.
TextureView deve essere utilizzato solo se SurfaceView non soddisfa le tue esigenze. Un esempio è quello in cui sono richieste animazioni fluide o lo scorrimento della superficie del video prima di Android 7.0 (livello API 24), come descritto nelle note seguenti. In
questo caso, è preferibile utilizzare TextureView solo quando SDK_INT è inferiore
a 24 (Android 7.0) e SurfaceView in caso contrario.
Il modulo Media3 ui-compose fornisce un elemento componibile PlayerSurface che collega
l'Player a un Surface in modo consapevole del ciclo di vita. I tipi di superficie
in questo caso sono:
Non esiste il tipo none, in quanto corrisponderebbe a non includere
PlayerSurface nell'albero della UI di Compose.

To\nfind out more about Surface objects in Android, read this [graphics\ndocumentation](https://source.android.com/docs/core/graphics/arch-sh).\n\nChoose a surface type for PlayerView\n------------------------------------\n\nThe `surface_type` attribute of [`PlayerView`](/reference/androidx/media3/ui/PlayerView) lets you set the type of\nsurface used for video playback. The allowed values are:\n\n- `surface_view` ([`SurfaceView`](/reference/android/view/SurfaceView))\n- `texture_view` ([`TextureView`](/reference/android/view/TextureView))\n- `spherical_gl_surface_view` ([`SphericalGLSurfaceView`](/reference/androidx/media3/exoplayer/video/spherical/SphericalGLSurfaceView)) - for spherical video playback\n- `video_decoder_gl_surface_view` ([`VideoDecoderGLSurfaceView`](/reference/androidx/media3/exoplayer/video/VideoDecoderGLSurfaceView)) - video rendering using extension renderers\n- `none` - which is for audio playback only and should be used to avoid having to create a surface because doing so can be expensive.\n\nIf the view is for regular video playback then `surface_view` or `texture_view`\nshould be used. [`SurfaceView`](/reference/android/view/SurfaceView) has a number of benefits over\n[`TextureView`](/reference/android/view/TextureView) for video playback:\n\n- Significantly [lower power consumption](/media/media3/exoplayer/battery-consumption) on many devices.\n- More accurate frame timing, resulting in smoother video playback.\n- Support for higher quality HDR video output on capable devices.\n- Support for secure output when playing DRM-protected content.\n- The ability to render video content at the full resolution of the display on Android TV devices that upscale the UI layer.\n\n`SurfaceView` should therefore be preferred over `TextureView` where possible.\n`TextureView` should be used only if `SurfaceView` does not meet your needs. One\nexample is where smooth animations or scrolling of the video surface is required\nprior to Android 7.0 (API level 24), as described in the following notes. For\nthis case, it's preferable to use `TextureView` only when [`SDK_INT`](/reference/android/os/Build.VERSION#SDK_INT) is less\nthan 24 (Android 7.0) and `SurfaceView` otherwise.\n| **Note:** `SurfaceView` rendering wasn't properly synchronized with view animations until Android 7.0 (API level 24). On earlier releases, improper synchronization could result in unwanted effects when a `SurfaceView` was placed into a scrolling container, or when it was animated. Unwanted effects included the view's contents appearing to lag slightly behind where it should be displayed, and the view turning black when animated. To achieve smooth animation or scrolling of video prior to Android 7.0, use `TextureView` rather than `SurfaceView`.\n| **Note:** The lifecycle of a `SurfaceView`'s surface is tied to view visibility, whereas a `TextureView`'s surface lifecycle is tied to window attachment and detachment. Therefore, in scrolling UIs that use `SurfaceView`, starting playback can take longer because the output surface becomes available slightly later. From Android 14 onwards, `PlayerView` uses [`SurfaceView.setSurfaceLifecycle(SURFACE_LIFECYCLE_FOLLOWS_ATTACHMENT)`](/reference/android/view/SurfaceView#setSurfaceLifecycle(int)) to avoid this behavior. If your app uses `SurfaceView` directly (without `PlayerView`) then you may want to enable this mode. Before Android 14, it's possible to work around the surface being destroyed by translating views off-screen when recycling them.\n| **Note:** Some Android TV devices run their UI layer at a resolution that's lower than the full resolution of the display, upscaling it for presentation to the user. For example, the UI layer may be run at 1080p on an Android TV that has a 4K display. On such devices, `SurfaceView` must be used to render content at the full resolution of the display. The full resolution of the display (in its current display mode) can be queried using [`Util.getCurrentDisplayModeSize`](/reference/androidx/media3/common/util/Util#getCurrentDisplayModeSize(android.content.Context)). The UI layer resolution can be queried using Android's [`Display.getSize`](/reference/android/view/Display#getSize(android.graphics.Point)) API.\n| **Note:** If you are using `PlayerView` inside of `AndroidView`, we cannot guarantee compatibility because `PlayerView` was not made with Compose in mind. One of the common problems for `SDK_INT == 34` is a stretched/cropped/leaked Surface that does not match the parent container (`AspectRatioFrameLayout`) correctly. You can opt into a Compose workaround by calling `PlayerView.setEnableComposeSurfaceSyncWorkaround`, but note that it causes issues with XML-based shared transitions.\n\nChoose a surface type in Compose\n--------------------------------\n\nIn Compose, the interop solution uses the `AndroidView` Composable to wrap\n[`SurfaceView`](/reference/android/view/SurfaceView) and [`TextureView`](/reference/android/view/TextureView). The two Composables that correspond to\nthat are [`AndroidExternalSurface`](/reference/kotlin/androidx/compose/foundation/package-summary#AndroidExternalSurface(androidx.compose.ui.Modifier,kotlin.Boolean,androidx.compose.ui.unit.IntSize,androidx.compose.foundation.AndroidExternalSurfaceZOrder,kotlin.Boolean,kotlin.Function1)) and [`AndroidEmbeddedExternalSurface`](/reference/kotlin/androidx/compose/foundation/package-summary#AndroidEmbeddedExternalSurface(androidx.compose.ui.Modifier,kotlin.Boolean,androidx.compose.ui.unit.IntSize,androidx.compose.ui.graphics.Matrix,kotlin.Function1)).\n\nMedia3 `ui-compose` module provides a [`PlayerSurface`](https://developer.android.com/reference/kotlin/androidx/media3/ui/compose/package-summary#PlayerSurface(androidx.media3.common.Player,androidx.compose.ui.Modifier,kotlin.Int)) Composable that links\nthe [`Player`](/reference/androidx/media3/common/Player) to a `Surface` in a lifecycle-aware manner. The surface types\nin this case are:\n\n- `SURFACE_TYPE_SURFACE_VIEW` (effectively [`AndroidExternalSurface`](/reference/kotlin/androidx/compose/foundation/package-summary#AndroidExternalSurface(androidx.compose.ui.Modifier,kotlin.Boolean,androidx.compose.ui.unit.IntSize,androidx.compose.foundation.AndroidExternalSurfaceZOrder,kotlin.Boolean,kotlin.Function1)))\n- `SURFACE_TYPE_TEXTURE_VIEW` (effectively [`AndroidEmbeddedExternalSurface`](/reference/kotlin/androidx/compose/foundation/package-summary#AndroidEmbeddedExternalSurface(androidx.compose.ui.Modifier,kotlin.Boolean,androidx.compose.ui.unit.IntSize,androidx.compose.ui.graphics.Matrix,kotlin.Function1)))\n\nThere is no type `none`, since that would correspond to not including the\n`PlayerSurface` in your Compose UI tree."]]
