class VideoPlayer : FrameLayout, TextureView.SurfaceTextureListener{
    
        private var url:String? = null

        constructor(context: Context, attributeSet: AttributeSet):super(context,attributeSet){
            init()
        }
    
        /**

        }
    
        fun setUp(url:String,headers:Map<String,String>?){
            this.url = url
            this.headers = headers
        }
    
        fun start(){
            mediaPlayer?.start()

            this.removeView(container)

                textureView = TextureView(context)
                textureView?.surfaceTextureListener = this
            }
            container?.removeView(textureView)
            val params = LayoutParams(

                LayoutParams.MATCH_PARENT,

        }
    
        private fun initMediaPlayer(){
            if(mediaPlayer == null){
                when(playerType){
                    PlayerTypes.TYPE_IJK -> mediaPlayer = IjkMediaPlayer()
                    PlayerTypes.TYPE_NATIVE -> mediaPlayer = AndroidMediaPlayer()
                    else -> mediaPlayer = IjkMediaPlayer()
                }
            }
    
            mediaPlayer?.setOnVideoSizeChangedListener { player, w, h, sar_num, sar_den ->
                Log.d("======","setOnVideoSizeChangedListener")
            }
    
            mediaPlayer?.setOnErrorListener { player, what, extra ->
                Log.d("======","setOnErrorListener")
                true
            }
    
            mediaPlayer?.setOnCompletionListener {
                Log.d("======","setOnCompletionListener")
            }
    
            mediaPlayer?.setOnPreparedListener {
                Log.d("======","setOnPreparedListener")
            }
    
            mediaPlayer?.setOnInfoListener { player, what, extra ->
                Log.d("======","setOnInfoListener")
                true
            }
    
            mediaPlayer?.setOnBufferingUpdateListener { player, percent ->
                Log.d("======","setOnBufferingUpdateListener")
    
            }
            
            openMediaPlayer()
        }
    
        private fun openMediaPlayer(){
            mediaPlayer?.setDataSource(context, Uri.parse(url),headers)
            mediaPlayer?.prepareAsync()
        }
    
    
        override fun onSurfaceTextureSizeChanged(p0: SurfaceTexture?, p1: Int, p2: Int) {
    
        }
    
        override fun onSurfaceTextureUpdated(p0: SurfaceTexture?) {
    
        }
    
        override fun onSurfaceTextureDestroyed(p0: SurfaceTexture?): Boolean {
            return p0 == null
        }
    
        override fun onSurfaceTextureAvailable(p0: SurfaceTexture?, p1: Int, p2: Int) {
            if(surfaceTexture == null){
                surfaceTexture = p0
                if(surface == null){
                    surface = Surface(surfaceTexture)
                }
                mediaPlayer?.setSurface(surface)
            }else{
                textureView?.surfaceTexture = surfaceTexture
            }
        }
    
    
    
    }

就是简单实现播放功能，其他的以后在添加

video_view.setPlayerType(PlayerTypes.TYPE_IJK)
    video_view.setUp(VideoDatas.videoUrls[2],null)
    video_view.start()
