如何投屏rtmp流

[lvjiancong]

1、我的投屏流地址rtmp://liteavapp.qcloud.com/live/liteavdemoplayerstreamid，用VLC播放正常
2、用Connect-SDK-Android投屏异常：Internal Server Error
3、我的测试代码如下
package com.connectsdk.sampler;

import android.app.AlertDialog;

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test);
    CapabilityFilter videoFilter = new CapabilityFilter(
            MediaPlayer.Play_Video,
            MediaControl.Any,
            VolumeControl.Volume_Up_Down

    CapabilityFilter imageCapabilities = new CapabilityFilter(
            MediaPlayer.Display_Image

    DiscoveryManager.getInstance().setPairingLevel(DiscoveryManager.PairingLevel.ON);
    DiscoveryManager.getInstance().setCapabilityFilters(videoFilter);
    DiscoveryManager discoveryManager = DiscoveryManager.getInstance();
    discoveryManager.addListener(this);
    discoveryManager.start();

我发现是因为DLNAService中的encodeURL()方法会对url进行转换成uri，这个过程出错了，我尝试去掉这个转换过程，直接返回原url，是能够正常投屏成功，这个转换的目的是什么呢，是否其他Service也有类似问题呢？
