No suitable media source factory found for content type: 2 (Exo Player)

Question

I'm trying to play a stream with ExoPlayer.

I add ExoPlayer to Project by downloading it from Github in order to use FFmpeg Renderer extensions. Previously, I was using it by adding implementations in app/build.gradle and it was working. But the stream didn't play the sound. Its codec wasn't supported by Exo. so I have to use FFmpeg extensions. To build and use extensions we have to go through the locally downloading method. But now this time, When I build and run the app it crashes with an error.

MyActivityLayout

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".view.activities.ExoTest">

    <com.google.android.exoplayer2.ui.PlayerView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

MyActivityCode

class ExoTest : AppCompatActivity() {
    private lateinit var mBinding: ActivityExoTestBinding
    private lateinit var player: SimpleExoPlayer

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        mBinding = ActivityExoTestBinding.inflate(layoutInflater)
        setContentView(mBinding.root)

        val streamURL = "http://202.57.43.60:8443/live/5748aabe4c9d661afbd7f4068248f664/99.m3u8"

        val defaultRenderersFactory = DefaultRenderersFactory(this).setExtensionRendererMode(DefaultRenderersFactory.EXTENSION_RENDERER_MODE_ON)

        player = SimpleExoPlayer.Builder(this, defaultRenderersFactory).build()

        val mediaItem = MediaItem.fromUri(streamURL)

        mBinding.videoView.player = player

        player.setMediaItem(mediaItem)

        player.prepare()
        player.playWhenReady = true
        player.play()
    }
}

This is the error that I get

Answer 1

Fixed I was missing this in app/build.gradle

implementation project(':exoplayer-library')

only this error is solved, the sound is still not playing.
