Streaming fluido
Mantieni tutto organizzato con le raccolte
Salva e classifica i contenuti in base alle tue preferenze.
ExoPlayer supporta Smooth Streaming con il formato contenitore FMP4. I flussi multimediali
devono essere demuxati, il che significa che video, audio e testo devono essere definiti in elementi
StreamIndex distinti nel manifest Smooth Streaming. Anche i formati audio e
video di esempio contenuti devono essere supportati (per i dettagli, consulta la sezione
Formati di esempio).

Guida all'integrazione |
Per riprodurre uno stream Smooth Streaming, devi fare affidamento sul modulo Smooth Streaming.
Kotlin
implementation("androidx.media3:media3-exoplayer-smoothstreaming:1.8.0")
Trendy
implementation "androidx.media3:media3-exoplayer-smoothstreaming:1.8.0"
Puoi quindi creare un MediaItem
per un URI manifest Smooth Streaming e passarlo
al player.
Kotlin
// Create a player instance.
val player = ExoPlayer.Builder(context).build()
// Set the media item to be played.
player.setMediaItem(MediaItem.fromUri(ssUri))
// Prepare the player.
player.prepare()
Java
// Create a player instance.
ExoPlayer player = new ExoPlayer.Builder(context).build();
// Set the media item to be played.
player.setMediaItem(MediaItem.fromUri(ssUri));
// Prepare the player.
player.prepare();
Se l'URI non termina con .ism/Manifest
, puoi passare
MimeTypes.APPLICATION_SS
a setMimeType
di MediaItem.Builder
per indicare esplicitamente
il tipo di contenuti.
ExoPlayer si adatterà automaticamente tra le rappresentazioni definite nel
manifest, tenendo conto sia della larghezza di banda disponibile sia delle funzionalità del dispositivo.
Per ulteriori opzioni di personalizzazione, puoi creare un SsMediaSource
e passarlo
direttamente al player anziché un MediaItem
.
Kotlin
// Create a data source factory.
val dataSourceFactory: DataSource.Factory = DefaultHttpDataSource.Factory()
// Create a SmoothStreaming media source pointing to a manifest uri.
val mediaSource: MediaSource =
SsMediaSource.Factory(dataSourceFactory).createMediaSource(MediaItem.fromUri(ssUri))
// Create a player instance.
val player = ExoPlayer.Builder(context).build()
// Set the media source to be played.
player.setMediaSource(mediaSource)
// Prepare the player.
player.prepare()
Java
// Create a data source factory.
DataSource.Factory dataSourceFactory = new DefaultHttpDataSource.Factory();
// Create a SmoothStreaming media source pointing to a manifest uri.
MediaSource mediaSource =
new SsMediaSource.Factory(dataSourceFactory).createMediaSource(MediaItem.fromUri(ssUri));
// Create a player instance.
ExoPlayer player = new ExoPlayer.Builder(context).build();
// Set the media source to be played.
player.setMediaSource(mediaSource);
// Prepare the player.
player.prepare();
Accedere al manifest
Puoi recuperare il manifest corrente chiamando Player.getCurrentManifest
.
Per Smooth Streaming, devi eseguire il cast dell'oggetto restituito su SsManifest
. Il
callback onTimelineChanged
di Player.Listener
viene chiamato anche ogni volta che
viene caricato il manifest. Ciò avverrà una volta per i contenuti on demand e
possibilmente molte volte per i contenuti live. Il seguente snippet di codice mostra come un'app
può fare qualcosa ogni volta che viene caricato il manifest.
Kotlin
player.addListener(
object : Player.Listener {
override fun onTimelineChanged(timeline: Timeline, @TimelineChangeReason reason: Int) {
val manifest = player.currentManifest
if (manifest is SsManifest) {
// Do something with the manifest.
}
}
}
)
Java
player.addListener(
new Player.Listener() {
@Override
public void onTimelineChanged(
Timeline timeline, @Player.TimelineChangeReason int reason) {
Object manifest = player.getCurrentManifest();
if (manifest != null) {
SsManifest ssManifest = (SsManifest) manifest;
// Do something with the manifest.
}
}
});

Media streams\nmust be demuxed, meaning that video, audio, and text must be defined in distinct\nStreamIndex elements in the SmoothStreaming manifest. The contained audio and\nvideo sample formats must also be supported (see the\n[sample formats](/media/media3/exoplayer/supported-formats#sample-formats) section for details).\n\n| Feature | Supported | Comments |\n|-------------------------------------|-----------|---------------------------------------------------------|\n| **Containers** | | |\n| FMP4 | YES | Demuxed streams only |\n| **Closed captions/subtitles** | | |\n| TTML | YES | Embedded in FMP4 |\n| **Content protection** | | |\n| PlayReady SL2000 | YES | Android TV only |\n| **Live playback** | | |\n| Regular live playback | YES | |\n| **Common Media Client Data (CMCD)** | YES | [Integration Guide](/guide/topics/media/exoplayer/cmcd) |\n\nUsing MediaItem\n---------------\n\nTo play a SmoothStreaming stream, you need to depend on the SmoothStreaming\nmodule. \n\n### Kotlin\n\n```kotlin\nimplementation(\"androidx.media3:media3-exoplayer-smoothstreaming:1.8.0\")\n```\n\n### Groovy\n\n```groovy\nimplementation \"androidx.media3:media3-exoplayer-smoothstreaming:1.8.0\"\n```\n\nYou can then create a `MediaItem` for a SmoothStreaming manifest URI and pass it\nto the player. \n\n### Kotlin\n\n```kotlin\n// Create a player instance.\nval player = ExoPlayer.Builder(context).build()\n// Set the media item to be played.\nplayer.setMediaItem(MediaItem.fromUri(ssUri))\n// Prepare the player.\nplayer.prepare()\n```\n\n### Java\n\n```java\n// Create a player instance.\nExoPlayer player = new ExoPlayer.Builder(context).build();\n// Set the media item to be played.\nplayer.setMediaItem(MediaItem.fromUri(ssUri));\n// Prepare the player.\nplayer.prepare();\n```\n\n\u003cbr /\u003e\n\nIf your URI doesn't end with `.ism/Manifest`, you can pass\n`MimeTypes.APPLICATION_SS` to `setMimeType` of `MediaItem.Builder` to explicitly\nindicate the type of the content.\n\nExoPlayer will automatically adapt between representations defined in the\nmanifest, taking into account both available bandwidth and device capabilities.\n\nUsing SsMediaSource\n-------------------\n\nFor more customization options, you can create a `SsMediaSource` and pass it\ndirectly to the player instead of a `MediaItem`. \n\n### Kotlin\n\n```kotlin\n// Create a data source factory.\nval dataSourceFactory: DataSource.Factory = DefaultHttpDataSource.Factory()\n// Create a SmoothStreaming media source pointing to a manifest uri.\nval mediaSource: MediaSource =\n SsMediaSource.Factory(dataSourceFactory).createMediaSource(MediaItem.fromUri(ssUri))\n// Create a player instance.\nval player = ExoPlayer.Builder(context).build()\n// Set the media source to be played.\nplayer.setMediaSource(mediaSource)\n// Prepare the player.\nplayer.prepare()\n```\n\n### Java\n\n```java\n// Create a data source factory.\nDataSource.Factory dataSourceFactory = new DefaultHttpDataSource.Factory();\n// Create a SmoothStreaming media source pointing to a manifest uri.\nMediaSource mediaSource =\n new SsMediaSource.Factory(dataSourceFactory).createMediaSource(MediaItem.fromUri(ssUri));\n// Create a player instance.\nExoPlayer player = new ExoPlayer.Builder(context).build();\n// Set the media source to be played.\nplayer.setMediaSource(mediaSource);\n// Prepare the player.\nplayer.prepare();\n```\n\n\u003cbr /\u003e\n\nAccessing the manifest\n----------------------\n\nYou can retrieve the current manifest by calling `Player.getCurrentManifest`.\nFor SmoothStreaming, you should cast the returned object to `SsManifest`. The\n`onTimelineChanged` callback of `Player.Listener` is also called whenever\nthe manifest is loaded. This will happen once for on-demand content and\npossibly many times for live content. The following code snippet shows how an app\ncan do something whenever the manifest is loaded. \n\n### Kotlin\n\n```kotlin\nplayer.addListener(\n object : Player.Listener {\n override fun onTimelineChanged(timeline: Timeline, @TimelineChangeReason reason: Int) {\n val manifest = player.currentManifest\n if (manifest is SsManifest) {\n // Do something with the manifest.\n }\n }\n }\n)\n```\n\n### Java\n\n```java\nplayer.addListener(\n new Player.Listener() {\n @Override\n public void onTimelineChanged(\n Timeline timeline, @Player.TimelineChangeReason int reason) {\n Object manifest = player.getCurrentManifest();\n if (manifest != null) {\n SsManifest ssManifest = (SsManifest) manifest;\n // Do something with the manifest.\n }\n }\n });\n```\n\n\u003cbr /\u003e\n\nCustomizing playback\n--------------------\n\nExoPlayer provides multiple ways for you to tailor playback experience to your\napp's needs. See the [Customization page](/guide/topics/media/exoplayer/customization) for examples."]]
