TransformerKt

A Kotlin coroutine wrapper around Media3's Transformer API.

Use the extension functions on a Transformer instance:

suspend fun transform(context: Context, input: Uri, output: File) {
    val transformer = Transformer.Builder(context).build()
    val result = transformer.start(input, output) { progress ->
        // Update UI with progress
    }

    // Handle the result
}

Or as a Flow:

suspend fun transform(context: Context, input: Uri, output: File) {
    val transformer = Transformer.Builder(context).build()
    transformer.start(input, output).collect (status) {
         // Handle the result
    }
}
