HarmonyOS ijkplayer使用rtsp播放直播流的延时问题

使用ijkplayer播放rtsp视频的时候，有些设备的延时会越来越高，请问有什么设置可以修改吗？下面是现在使用的设置。

if (!!this.mContext) {
  mIjkMediaPlayer.setContext(this.mContext,'xcomponentId1');
}
if (CONTROL_PlayStatus == PlayStatus.INIT) {
  mIjkMediaPlayer.reset();
}
CONTROL_PlayStatus = PlayStatus.PLAY;
//设置debug模式
mIjkMediaPlayer.setDebug(true);
//初始化配置
mIjkMediaPlayer.native_setup();
//设置视频源
mIjkMediaPlayer.setDataSource(url);

// 如果是rtsp协议，可以优先用tcp(默认是用udp)
if(this.camera?.rtsp===2){
  mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "rtsp_transport", "udp");
}else{
  mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "rtsp_transport", "tcp");
}
mIjkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec", "1");

// 屏幕常亮
mIjkMediaPlayer.setScreenOnWhilePlaying(true);
