Provider-based Kotlin Multiplatform media client with a built-in YouTube provider for audio downloads and English transcripts.

repositories {
    mavenCentral()
}

kotlin {
    sourceSets {
        commonMain.dependencies {
            implementation("dev.lizz.ytdl:youtube-downloader-core:0.1.0-alpha04")
            implementation("dev.lizz.ytdl:youtube-downloader-engine-youtube:0.1.0-alpha04")
        }
    }
}

Published Maven coordinates and Kotlin packages use dev.lizz.ytdl.

import dev.lizz.ytdl.core.AudioDownloadOptions
import dev.lizz.ytdl.core.AudioDownloadRequest
import dev.lizz.ytdl.providers.youtube.JvmYoutubeProviderFactory

suspend fun downloadAudio(): String {
    val client = JvmYoutubeProviderFactory.createDefault()
    return client.downloadAudio(
        AudioDownloadRequest(
            url = "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
            options = AudioDownloadOptions(outputPath = "./downloads")
        )
    ).path
}

Android uses AndroidYoutubeProviderFactory.create(context).

iOS uses IosYoutubeProviderFactory.createDefault().

• youtube-downloader-core: public KMP API
• youtube-downloader-engine-youtube: built-in YouTube provider implementation and factories
• android-native-media: owned Android LAME bridge used by the engine
• samples: Compose Multiplatform sample module
• androidApp: Android sample host app
• iosApp: iOS sample host app

• YouTube-only
• audio download and English transcript extraction only
• signatureCipher, n, and anti-bot handling are still incomplete
• JVM/Desktop MP3 conversion still requires local ffmpeg for now
