Android VideoView無法播放多播流

我正在嘗試播放使用h264/aac編碼並通過多播從VLC傳輸的流。我在啓動視頻視圖之前設置了wifi多播鎖定。使用從SD卡讀取SDP文件，我在logcat中在啓動時得到這些錯誤： Android VideoView無法播放多播流

 
E/ASessionDescription: ASessionDescription::getServerSessionURL: Did not get the Server URL info from the control attribute...Checking in Origin Info 
E/ASessionDescription: ASessionDescription::getServerURLFromOriginAndSessionName : URL info not present in the Session name 
E/ASessionDescription: ASessionDescription::getServerSessionURL: Did not get the Server URL info Origin field 
E/NuPlayer: getServerSessionURL for SDP Failed

這是我的SDP文件的內容：

 
v=0 
o=- 2890844526 2890842807 IN IP4 192.168.16.1 
s=Multicast stream test 
c=IN IP4 239.10.1.1/127 
t=0 0 
a=recvonly 
m=video 5004 RTP/AVP 96 97

a=fmtp:97 profile-level-id=1;mode=AAC-hbr;sizelength=13;indexlength=3;indexltalength=3; config=1210 
a=orient:portrait

所有設備都在同一個網絡上。這顯示了代碼的簡單：

VideoView videoView = (VideoView) findViewById(R.id.playback_view); 
videoView.setVideoPath(Environment.getExternalStorageDirectory() + "/test.sdp"); 
videoView.start();

我也試過這種VLC產生的SDP與MP3音頻，它也無法播放
