How to turn on the simulcast?

[AkaneAzumi]

Hi, I used your SDK in my code and everything is fine with the push stream. But when I added the simulcast related configuration to the code, there was only one stream when played. Here's my code. Is my configuration incorrect?
` val encodings= mutableListOf<RtpParameters.Encoding>()
encodings.add(RtpParameters.Encoding("h", true, 1.0))
encodings.add(RtpParameters.Encoding("m", true, 2.0))
encodings.add(RtpParameters.Encoding("l", true, 4.0))

        val init = RtpTransceiver.RtpTransceiverInit(
            RtpTransceiver.RtpTransceiverDirection.SEND_RECV, Collections.emptyList(), encodings
        )

        peerConnection!!.addTransceiver(MediaStreamTrack.MediaType.MEDIA_TYPE_VIDEO, init)`

`val decoderFactory: VideoDecoderFactory =
DefaultVideoDecoderFactory(eglBase!!.eglBaseContext)
val encoderFactory: VideoEncoderFactory = DefaultVideoEncoderFactory(
eglBase!!.eglBaseContext,
true,
true
)

    val simulcastVideo = SimulcastVideoEncoderFactory(encoderFactory,encoderFactory)

    PeerConnectionFactory.initialize(
        PeerConnectionFactory.InitializationOptions
            .builder(context)
            .createInitializationOptions()
    )
    PeerConnectionFactory.builder()
        .setOptions(PeerConnectionFactory.Options())
        .setAudioDeviceModule(JavaAudioDeviceModule.builder(context).createAudioDeviceModule())
        .setVideoEncoderFactory(simulcastVideo)
        .setVideoDecoderFactory(decoderFactory)
        .createPeerConnectionFactory()`
