不要复制粘贴把文件素材改成自己的ID也要改成自己的，RpxUtil.rpx 是我自己写的UI适配插件用来适配各种屏幕的。

第一步在需要显示视频的地方添加视频容器组件

<SurfaceProvider
                    ohos:id="$+id:money_list_media_player"
                    ohos:width="match_parent">

                </SurfaceProvider>1.

编码实现

第二步创建播放器

全局定义一个播放器

private static Player player;

 player=new Player(getContext());1.

第三步创建视频相关的回调方法

//播放处死哈 
private void playLocalFile(Surface surface) {

        try {
            RawFileDescriptor filDescriptor = getResourceManager().getRawFileEntry("resources/rawfile/mediamp4.mp4").openRawFileDescriptor();
            Source source = new Source(filDescriptor.getFileDescriptor(),filDescriptor.getStartPosition(),filDescriptor.getFileSize());
            player.setSource(source);
            player.setVideoSurface(surface);
            player.setPlayerCallback(new VideoPlayerCallback());
            player.prepare();
            sfProvider.setTop(0);
//            player.play();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
//视频加载回调
    private class VideoSurfaceCallback implements SurfaceOps.Callback {
        @Override
        public void surfaceCreated(SurfaceOps surfaceOps) {
            HiLog.info(logLabel,"surfaceCreated() called.");
            if (sfProvider.getSurfaceOps().isPresent()) {
                Surface surface = sfProvider.getSurfaceOps().get().getSurface();
                playLocalFile(surface);
            }
        }
        @Override
        public void surfaceChanged(SurfaceOps surfaceOps, int i, int i1, int i2) {
            HiLog.info(logLabel,"surfaceChanged() called.");
        }
        @Override
        public void surfaceDestroyed(SurfaceOps surfaceOps) {
            HiLog.info(logLabel,"surfaceDestroyed() called.");
        }
    }


//视频播放回调
    private class VideoPlayerCallback implements Player.IPlayerCallback {
        @Override
        public void onPrepared() {
            HiLog.info(logLabel,"onPrepared");
        }
        @Override
        public void onMessage(int i, int i1) {
            HiLog.info(logLabel,"onMessage");
        }
        @Override
        public void onError(int i, int i1) {
            HiLog.info(logLabel,"onError: i=" + i + ", i1=" + i1);
        }
        @Override
        public void onResolutionChanged(int i, int i1) {
            HiLog.info(logLabel,"onResolutionChanged");
        }
        @Override
        public void onPlayBackComplete() {
            HiLog.info(logLabel,"onPlayBackComplete");
            if (player != null) {
                player.stop();
                player = null;
            }
        }
        @Override
        public void onRewindToComplete() {
            HiLog.info(logLabel,"onRewindToComplete");
        }
        @Override
        public void onBufferingChange(int i) {
            HiLog.info(logLabel,"onBufferingChange");
        }
        @Override
        public void onNewTimedMetaData(Player.MediaTimedMetaData mediaTimedMetaData) {
            HiLog.info(logLabel,"onNewTimedMetaData");
        }
        @Override
        public void onMediaTimeIncontinuity(Player.MediaTimeInfo mediaTimeInfo) {
            HiLog.info(logLabel,"onMediaTimeIncontinuity");
        }

第四步调用视频渲染

//这个是全局的跟上面的播放器一样
 private SurfaceProvider sfProvider;

sfProvider =(SurfaceProvider) findComponentById(ResourceTable.Id_money_list_media_player);
sfProvider.getSurfaceOps().get().addCallback(new VideoSurfaceCallback());
sfProvider.pinToZTop(true);
sfProvider.setWidth(ComponentContainer.LayoutConfig.MATCH_PARENT);
sfProvider.setHeight((int) RpxUtil.rpx(350,getContext()));1.
