基本流程如下
1. 基础的初始化和参数设定 libPlayer new SmartPlayerJniV2();myContext this.getApplicationContext();sSurfaceView (SurfaceView) this.findViewById(R.id.surface);surface_renderer new RGBSurfaceRenderer(sSurfaceView);
private void InitAndSetConfig() {playerHandle libPlayer.SmartPlayerOpen(myContext);if (playerHandle 0) {Log.e(TAG, surfaceHandle with nil..);return;}libPlayer.SetSmartPlayerEventCallbackV2(playerHandle,new EventHandeV2());libPlayer.SmartPlayerSetBuffer(playerHandle, playBuffer);// set report download speed(默认2秒一次回调 用户可自行调整report间隔)libPlayer.SmartPlayerSetReportDownloadSpeed(playerHandle, 1, 2);libPlayer.SmartPlayerSetFastStartup(playerHandle, isFastStartup ? 1 : 0);//设置RTSP超时时间int rtsp_timeout 10;libPlayer.SmartPlayerSetRTSPTimeout(playerHandle, rtsp_timeout);//设置RTSP TCP/UDP模式自动切换int is_auto_switch_tcp_udp 1;libPlayer.SmartPlayerSetRTSPAutoSwitchTcpUdp(playerHandle, is_auto_switch_tcp_udp);libPlayer.SmartPlayerSaveImageFlag(playerHandle, 1);// It only used when playback RTSP stream..// libPlayer.SmartPlayerSetRTSPTcpMode(playerHandle, 1);playbackUrl rtmp://202.69.69.180:443/webcast/bshdlive-pc;//playbackUrl rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov;libPlayer.SmartPlayerSetUrl(playerHandle, playbackUrl);}
2. 设置External Render回调RGBA数据
libPlayer.SmartPlayerSetExternalRender(playerHandle, new RGBAExternalRender());
Log.i(TAG, Start playback stream);InitAndSetConfig();// External RenderlibPlayer.SmartPlayerSetExternalRender(playerHandle, new RGBAExternalRender());libPlayer.SmartPlayerSetAudioOutputType(playerHandle, 0);if (isMute) {libPlayer.SmartPlayerSetMute(playerHandle, isMute ? 1: 0);}if (isHardwareDecoder) {int isSupportHevcHwDecoder libPlayer.SetSmartPlayerVideoHevcHWDecoder(playerHandle, 1);int isSupportH264HwDecoder libPlayer.SetSmartPlayerVideoHWDecoder(playerHandle, 1);Log.i(TAG, isSupportH264HwDecoder: isSupportH264HwDecoder , isSupportHevcHwDecoder: isSupportHevcHwDecoder);}libPlayer.SmartPlayerSetLowLatencyMode(playerHandle, isLowLatency ? 1: 0);libPlayer.SmartPlayerSetFlipVertical(playerHandle, is_flip_vertical ? 1 : 0);libPlayer.SmartPlayerSetFlipHorizontal(playerHandle, is_flip_horizontal ? 1 : 0);libPlayer.SmartPlayerSetRotation(playerHandle, rotate_degrees);int iPlaybackRet libPlayer.SmartPlayerStartPlay(playerHandle);if (iPlaybackRet ! 0) {Log.e(TAG, Call SmartPlayerStartPlay failed..);return;}surface_renderer.StartRender();btnStartStopPlayback.setText(停止播放 );isPlaying true;Log.i(TAG, Start playback stream--);
3. 回调RGBA数据 class RGBAExternalRender implements NTExternalRender {// public static final int NT_FRAME_FORMAT_RGBA 1;// public static final int NT_FRAME_FORMAT_ABGR 2;// public static final int NT_FRAME_FORMAT_I420 3;private int width_ 0;private int height_ 0;private int row_bytes_ 0;private ByteBuffer rgba_buffer_ null;Overridepublic int getNTFrameFormat() {Log.i(TAG, RGBAExternalRender::getNTFrameFormat return NT_FRAME_FORMAT_RGBA);return NT_FRAME_FORMAT_RGBA;}Overridepublic void onNTFrameSizeChanged(int width, int height) {width_ width;height_ height;row_bytes_ width_ * 4;Log.i(TAG, RGBAExternalRender::onNTFrameSizeChanged width_: width_ height_: height_);rgba_buffer_ ByteBuffer.allocateDirect(row_bytes_ * height_);}Overridepublic ByteBuffer getNTPlaneByteBuffer(int index) {if (index 0) {return rgba_buffer_;} else {Log.e(TAG,RGBAExternalRender::getNTPlaneByteBuffer index error: index);return null;}}Overridepublic int getNTPlanePerRowBytes(int index) {if (index 0) {return row_bytes_;} else {Log.e(TAG,RGBAExternalRender::getNTPlanePerRowBytes index error: index);return 0;}}public void onNTRenderFrame(int width, int height, long timestamp) {if (rgba_buffer_ null)return;// rgba_buffer_.rewind();// copy buffer// test// byte[] test_buffer new byte[16];// rgba_buffer_.get(test_buffer);//Log.i(TAG, RGBAExternalRender:onNTRenderFrame w width h// height timestamp timestamp);// Log.i(TAG, RGBAExternalRender:onNTRenderFrame rgba: // bytesToHexString(test_buffer));if ( surface_renderer ! null){surface_renderer.SetRGBImage(width, height, rgba_buffer_);}}}
4. 对视频view进行放大缩小等状态处理 SuppressLint(ClickableViewAccessibility)public RGBSurfaceRenderer(SurfaceView view){surface_holder_ view.getHolder();if (surface_holder_ null){Log.e(TAG, RGBSurfaceRenderer, surfaceHolder with null..);return;}surface_holder_.addCallback(this);view.setOnTouchListener(new View.OnTouchListener(){Overridepublic boolean onTouch(View v, MotionEvent event){Log.e(TAG, onTouch called..);switch (event.getAction() MotionEvent.ACTION_MASK) {case MotionEvent.ACTION_DOWN:start_point_.set(event.getX(), event.getY());status_ DRAG;break;case MotionEvent.ACTION_POINTER_DOWN:float distance spacing(event);if (distance 10f) {status_ ZOOM;start_distance_ distance;}break;case MotionEvent.ACTION_MOVE:if (status_ DRAG) {dragAction(event);} else {if (event.getPointerCount() 1)return true;zoomAcition(event);}break;case MotionEvent.ACTION_UP:case MotionEvent.ACTION_POINTER_UP:status_ NONE;break;default:break;}return true;}});}5. 关闭播放
if (isPlaying) {Log.i(TAG, Stop playback stream);int iRet libPlayer.SmartPlayerStopPlay(playerHandle);if (iRet ! 0) {Log.e(TAG, Call SmartPlayerStopPlay failed..);return;}surface_renderer.StopRender();libPlayer.SmartPlayerClose(playerHandle);playerHandle 0;isPlaying false;btnStartStopPlayback.setText(开始播放 );Log.i(TAG, Stop playback stream--);}
