android ijkplayer简单使用

class VideoPlayer : FrameLayout, TextureView.SurfaceTextureListener{

    private var url:String? = null
    private var headers:Map<String,String>? = null
    private var mediaPlayer: IMediaPlayer? = null   //播放器
    private var container: FrameLayout? = null      //播放器根目录
    private var textureView: TextureView? = null   //视频显示视图
    private var surfaceTexture: SurfaceTexture? = null
    private var playerType:Int = PlayerTypes.TYPE_IJK
    private var surface: Surface? = null

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

    /**
     * 设置播放器类型
     *
     * @param playerType IjkPlayer or MediaPlayer.
     */
    fun setPlayerType(playerType: Int) {
        this.playerType = playerType
    }

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

    fun start(){
        mediaPlayer?.start()
    }

    private fun init(){
        container = FrameLayout(context)
        this.removeView(container)
        val params = LayoutParams(
            LayoutParams.MATCH_PARENT,
            LayoutParams.MATCH_PARENT
        )
        this.addView(container,params)

        initTextureView()
        initMediaPlayer()
    }

    private fun initTextureView(){
        if(textureView == null){
            textureView = TextureView(context)
            textureView?.surfaceTextureListener = this
        }
        container?.removeView(textureView)
        val params = LayoutParams(
            LayoutParams.MATCH_PARENT,
            LayoutParams.MATCH_PARENT,
            Gravity.CENTER
        )
        container?.addView(textureView,0,params)
    }

    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()
