1 在海马云游戏管理平台进行配置游戏的清晰度参数（高清、超清、流畅）；

2 调用开始游戏后，如果成功会有 sceneId = “play” 的场景回调

   onSceneChanged ===> {"extraInfo":{"cur_rate":"200"},"sceneId":"play"}

3 SDK 调用 HmcpManager.getInstance().getResolutionData() 获取当前游戏的清晰度列表；

   "resolution":[
     {"bitRate":"9600000","defaultChoice":"0","frameRate":60,"id":"4","name":"1080P","resolution":"1920x1080"},
     {"bitRate":"4000000","defaultChoice":"0","frameRate":60,"id":"2","name":"标清","resolution":"960x540"},
     {"bitRate":"3200000","defaultChoice":"1","frameRate":60,"id":"3","name":"高清","resolution":"1280x720"},
     {"bitRate":"2400000","defaultChoice":"0","frameRate":60,"id":"1","name":"流畅","resolution":"848x480"}
   ]

4 监听回调函数onSceneChanged 并收到 sceneId=”crtp” 消息：

   onSceneChanged ===> {"extraInfo": {"delay_less_minimum":"0","minimum":0},"sceneId":"crtp"}

5 开始切换码率：

   // 发起切换码率
   recordSceneEvent ===> crst{"des":"1024","method":0,"source":"50000"}
   // 切换码率时回调
   onSceneChanged ===> 
   {"extraInfo":{"des":"1024","method":0,"source":"50000"},"sceneId":"crst"}

5.1 果手动调用 onSwitchResolution() 切换码率；

5.2 onSceneChanged 接收到切换码率的消息回调 scenedId=”crst”

6 onSceneChanged 收到scenedId=”cred”切换码率后结果：

   recordSceneEvent ===> cred {"cur_rate":"500","result":1}
