Media3 1.11 is out. Powering the vast majority of top Android media apps, this release brings new features, bug fixes, and improvements across playback, editing, and UI components. We’re expanding our Jetpack Compose UI modules with customizable Read on for key highlights, and check out the full release notes<\/a> for a comprehensive list of changes.<\/p>\n With Android becoming Compose-first, we are continuing to expand the The Material 3 Player Composable now supports dedicated content slots for The For apps with sliding-window media feeds (for example, short-form vertical video), managing multiple ExoPlayer instances efficiently is a common challenge. Media3 1.11 introduces The new A new We added several new reactive state holders to We’ll continue working on new additions and more customization options in upcoming releases. Please share your thoughts on the project issue tracker<\/a>.<\/p>\n Media3 1.11 updates the Cast extension with programmatic configuration options and support for OS-level routing.<\/p>\n You can now configure the Cast extension using Setting Apps using Jetpack Compose can now easily add the Media routing button (also known as Cast button), which automatically observes the dialog state and updates accordingly. No further logic needed when used together with Media3’s Eclipsa Video<\/a> promises a more consistent HDR experience across devices, with a consistent baseline HDR white, adaptive headroom depending on the screen and the surroundings, ensuring the creative intent is preserved on all devices.<\/p>\n ExoPlayer now supports playback of the necessary HAGC (ST 2094-50) timed metadata for progressive media (MP4, Matroska). The player automatically merges HAGC metadata tracks with the associated video track and delivers the metadata out-of-band to the decoder on API 37+ devices. On older devices, ExoPlayer seamlessly falls back to providing a standard HDR playback experience without the adjustments.<\/p>\n Illustration to show benefits of Eclipsa Video HDR, like more consistent color contract<\/span><\/p>\n A new For apps that don\u2019t override We’ve added two new dedicated muxers: Player<\/code> slots and easy to use defaults, interactive gestures, state observers, and short-form video preloading using PlayerPool<\/code>. We also modernized the Media3 Cast integration with SystemUI Output Switcher support, introduced a new Ktor HTTP client network extension, and added new muxing utilities for Ogg and WAV files.<\/p>\nPlayback UI and Compose<\/h2>\n
media3-ui-compose<\/code> and media3-ui-compose-material3<\/code> modules. This update introduces more granular control over your player layout, richer interaction patterns, and deeper integration with Material3.<\/p>\nCustomizable Player layout<\/h3>\n
topControls<\/code>, centerControls<\/code>, bottomControls<\/code>, and errorOverlay<\/code>. You can drop in your own Composables or use the ready-made defaults published in PlayerDefaults<\/code>:<\/p>\nPlayer(\n player = player,\n topControls = { PlayerDefaults.TopControls(player) },\n centerControls = { PlayerDefaults.CenterControls(player) },\n bottomControls = { PlayerDefaults.BottomControls(player) },\n)<\/code><\/pre>\nPlayer<\/code> Composable also integrates FocusRequester<\/code> support, enabling seamless D-pad and keyboard navigation on Android TV, foldables, and desktop environments. large-screen devices.<\/p>\n<\/a>Example for a Composable Player with customized controls<\/span><\/div>\nGestures and playback speed control<\/h3>\n
PlaybackSpeedState<\/code> now provides a fast-forward\/slow-motion API. The demo-compose<\/code> app<\/a> showcases this with a long-press gesture to fast-forward playback and seeking with double tap. Combined with the ProgressSlider<\/code> introduced in 1.10, the Compose player UI now offers rich touch and gesture interactions out of the box.<\/p>\nShort-form video preloading with PlayerPool<\/h3>\n
PlayerPool<\/code> (in common-ktx<\/code>) and rememberPooledPlayer<\/code> (in ui-compose<\/code>) to handle player recycling and preloading automatically.<\/p>\nShortFormPlayerScreen<\/code> in demo-compose<\/code> shows this in action, a vertically paging feed where players are pooled, preloaded, and seamlessly recycled as the user scrolls.<\/p>\nMiniController<\/h3>\n
MiniController<\/code> Composable in media3-ui-compose-material3<\/code> provides a compact playback bar displaying the current item’s title, artist, artwork, and progress alongside play\/pause controls. As all our default Composables in media3-ui-compose-material3<\/code>, the MiniController<\/code> supports Material3 Dynamic Color integration, allowing it to automatically adapt to the user’s wallpaper theme.This is ideal for persistent bottom-sheet or mini-player affordances, for example while the user browses content or during active Cast sessions.<\/p>\n<\/a>The Media3 MiniController showing album art, media metadata and basic controls<\/span><\/div>\nExpanded state holders for metadata and errors<\/h3>\n

CastParams and SystemUI Output Switcher<\/h3>\n

Eclipsa Video – HAGC dynamic HDR metadata (API 37+)<\/h3>\n
<\/a><\/div>\nNew Ktor HTTP client extension<\/h3>\n
media3-datasource-ktor<\/code> extension module provides KtorDataSource<\/code>, backed by the Ktor<\/a> HTTP stack. This offers a Kotlin-first, coroutine-friendly alternative to the existing Cronet and OkHttp data source modules.<\/p>\nAsynchronous MediaSession connections<\/h3>\n
MediaSession.Callback<\/code> now includes onConnectAsync()<\/code>, which lets you process controller connection attempts asynchronously \u2014 for example, to verify authorization before accepting a connection. You can return an immediate Future with Futures.immediateFuture(ConnectionResult)<\/code> for the same behavior as the existing onConnect<\/code>.<\/p>\noverride fun onConnectAsync(\n session: MediaSession,\n controller: MediaSession.ControllerInfo\n): ListenableFutureSafer MediaSession defaults<\/h3>\n
onConnect<\/code> or onConnectAsync<\/code> in MediaSession.Callback<\/code>, the library now defaults to a more secure configuration. Specifically, session data is no longer shared by default with untrusted controllers, meaning third-party or non-system apps lacking notification access are restricted from accessing session data unless you explicitly implement these callback methods to authorize the connection.<\/p>\nNew Muxer implementations & container parsing<\/h2>\n
OggMuxer and WavMuxer<\/h3>\n
OggMuxer<\/code> for muxing OPUS and VORBIS streams into standard .ogg files, and WavMuxer<\/code> for generating uncompressed and floating-point PCM .wav audio files.<\/p>\nContainer parsing and track references<\/h3>\n
\n
Mp4Muxer.addTrackReference<\/code> allows linking dependent metadata or aux tracks to primary video streams.<\/li>\n
