Start

If you are building with Gradle, simply add the following code to your project:

You need to configure your kotlin environment. Project root build.gradle

buildscript {
    ext.kotlin_version = '1.2.30'//Latest kotlin version
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
allprojects {
    repositories {
        google()
        jcenter()
    }
}

Module build.gradle

dependencies {
    implementation 'com.lmy.codec:hardwarevideocodec:1.7.3'
    implementation 'com.lmy.codec:rtmp:1.7.3'//If you want to use RTMP stream.
}

For record mp4

class MainActivity : AppCompatActivity() {
    private lateinit var mRecorder: VideoRecorderImpl
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val mTextureView = TextureView(this)
        setContentView(mTextureView)
        mRecorder = VideoRecorderImpl(this).apply {
            reset()
            setOutputUri("${Environment.getExternalStorageDirectory().absolutePath}/test.mp4")
            setOutputSize(720, 1280)//Default 720x1280
            setFps(30)
            setFilter(getDefaultFilter())
            setPreviewDisplay(mTextureView)
        }
        mRecorder.prepare()
        //For recording control
        mTextureView.setOnTouchListener { v, event ->
            when (event.action) {
                MotionEvent.ACTION_DOWN -> {
                    if (mRecorder.prepared())
                        mRecorder.start()
                }
                MotionEvent.ACTION_UP -> {
                    if (mRecorder.started())
                        mRecorder.pause()
                }
            }
            true
        }
    }

    private fun getDefaultFilter(): BaseFilter = GroupFilter.create(BeautyV4Filter())
            .addSticker(TextSticker().apply {
                setText(TextSticker.Text("HWVC", 56f).apply {
                    x = 0.8f
                    y = 0.03f
                })
            })
            .addSticker(ImageSticker().apply {
                setImage(ImageSticker.Image().apply {
                    x = 0.03f
                    y = 0.03f
                    scale = 1.6f
                    bitmap = BitmapFactory.decodeResource(resources, R.mipmap.ic_logo_hwvc)
                })
            })

    override fun onDestroy() {
        super.onDestroy()
        mRecorder.release()
    }
}

For live

        override fun onStop() {
        }

        override fun onPrepared(encoder: Encoder) {
            mRecorder.start()
        }

        override fun onRecord(encoder: Encoder, timeUs: Long) {
        }

        override fun onError(error: Int, msg: String) {

        }
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val mTextureView = TextureView(this)

        mRecorder = VideoRecorderImpl(this).apply {
            reset()
            setOutputUri("rtmp://192.168.16.125:1935/live/livestream")
            setOutputSize(720, 1280)//Default 720x1280
            setFps(30)
            setFilter(getDefaultFilter())//Default NormalFilter
            setPreviewDisplay(mTextureView)
            setOnStateListener(onStateListener)
        }
        mRecorder.prepare()
    }

    private fun getDefaultFilter(): BaseFilter = GroupFilter.create(BeautyV4Filter())
            .addSticker(TextSticker().apply {

                })
            })
            .addSticker(ImageSticker().apply {
                setImage(ImageSticker.Image().apply {
