O ExoPlayer é compatível com SmoothStreaming usando o formato de contêiner FMP4. Os fluxos de mídia precisam ser demuxados, ou seja, vídeo, áudio e texto precisam ser definidos em elementos StreamIndex distintos no manifesto do SmoothStreaming. Os formatos de amostra de áudio e vídeo contidos também precisam ser compatíveis. Consulte a seção Formatos de amostra para mais detalhes.

Para reproduzir um stream do SmoothStreaming, é necessário depender do módulo
SmoothStreaming.
Kotlin
implementation("androidx.media3:media3-exoplayer-smoothstreaming:1.8.0")
Groovy
implementation "androidx.media3:media3-exoplayer-smoothstreaming:1.8.0"
Em seguida, crie um MediaItem
para um URI de manifesto do SmoothStreaming e transmita-o
ao 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 o URI não terminar com .ism/Manifest
, transmita
MimeTypes.APPLICATION_SS
para setMimeType
de MediaItem.Builder
para indicar explicitamente
o tipo de conteúdo.
O ExoPlayer se adapta automaticamente entre as representações definidas no
manifesto, considerando a largura de banda disponível e os recursos do dispositivo.
Para mais opções de personalização, crie um SsMediaSource
e transmita-o
diretamente ao player em vez de um 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();
Como acessar o manifesto
Para recuperar o manifesto atual, chame Player.getCurrentManifest
.
Para o SmoothStreaming, transmita o objeto retornado para SsManifest
. O callback
onTimelineChanged
de Player.Listener
também é chamado sempre que
o manifesto é carregado. Isso vai acontecer uma vez para conteúdo on demand e
possivelmente muitas vezes para conteúdo ao vivo. O snippet de código a seguir mostra como um app
pode fazer algo sempre que o manifesto é carregado.
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.
}
}
});
Personalizar a reprodução
O ExoPlayer oferece várias maneiras de personalizar a experiência de reprodução de acordo com as necessidades do seu app. Consulte a página de personalização para ver exemplos.

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."]]
