You can add this library to your project using Gradle.

Multiplatform To add to a multiplatform project, add the dependency to the common source-set:

repositories {
    mavenCentral()
}

kotlin {
    sourceSets {
        commonMain {
            dependencies {
                implementation("io.github.ilyapavlovskii:youtubeplayer-compose:${latest_version}")
            }
        }
    }
}

Usage

val coroutineScope = rememberCoroutineScope()
val hostState = remember { YouTubePlayerHostState() }

when(val state = hostState.currentState) {
    is YouTubePlayerState.Error -> {
        Text(text = "Error: ${state.message}")
    }
    YouTubePlayerState.Idle -> {
        // Do nothing, waiting for initialization
    }
    is YouTubePlayerState.Playing -> {
        // Update UI button states
    }
    YouTubePlayerState.Ready -> coroutineScope.launch {
        hostState.loadVideo(YouTubeVideoId("ufKj1sBrC4Q"))
    }
}

YouTubePlayer(
    modifier = Modifier
        .fillMaxWidth()
        .height(300.dp)
        .gesturesDisabled(),
    hostState = hostState,
    options = SimpleYouTubePlayerOptionsBuilder.builder {
        autoplay(true)
        controls(false)
        rel(false)
        ivLoadPolicy(false)
        ccLoadPolicy(false)
        fullscreen = true
    },
)

Composable function has the next major params:

• options - to player options builder. All parameters wrapped from official youtube iframe documentation.
• hostState - controller for track youtube player state and execute one time commands

YouTubePlayerHostState

The main controller. Contains 2 major public components:

• currentState - defines actual youtube player state on the screen. Might be: Idle, Ready, Playing, Error
• executeCommand - suspend function to execution player commands. Receives only one argument - YouTubeExecCommand. Also have an additional sugar functions like:

suspend fun loadVideo(videoId: YouTubeVideoId) = executeCommand(YouTubeExecCommand.LoadVideo(videoId))
suspend fun play() = executeCommand(YouTubeExecCommand.Play)
suspend fun pause() = executeCommand(YouTubeExecCommand.Pause)
suspend fun seekTo(duration: Duration) = executeCommand(YouTubeExecCommand.SeekTo(duration))
suspend fun seekBy(duration: Duration) = executeCommand(YouTubeExecCommand.SeekBy(duration))
suspend fun mute() = executeCommand(YouTubeExecCommand.Mute)
suspend fun unMute() = executeCommand(YouTubeExecCommand.Unmute)
suspend fun setVolume(volume: Int) = executeCommand(YouTubeExecCommand.SetVolume(volume))
suspend fun setPlaybackRate(rate: Float) = executeCommand(YouTubeExecCommand.SetPlaybackRate(rate))
suspend fun toggleFullScreen() = executeCommand(YouTubeExecCommand.ToggleFullscreen)

YouTubePlayerState

YouTube player state defines actual youtube player state on the screen. Contains the next possible states:

• Idle - Idle state means that player is not initialized yet

currentTime: Duration - current time of the video
quality: YouTubeEvent.PlaybackQualityChange.Quality - quality of the video, see [YouTubeEvent.PlaybackQualityChange.Quality]
isPlaying: Boolean - is video playing

• Error - Defines error state with error message inside.

YouTubeExecCommand

• SeekTo(val duration: Duration) - seek video to a specified time

• SeekBy(val duration: Duration) - seek video by a specified time
