Video ffplay在切换了-an和-vn选项的HLS流媒体上崩溃

当我尝试通过键入开始无声（无音频和视频流）播放HLS（HTTP直播）时

ffplay -an -vn -i "http://localhost:8080/video/find?startTime=
1376716800000&endTime=1376717400000 

我在控制台上收到下一条错误消息：

这是ffplay无法在没有音频/视频流的情况下播放视频的错误或功能吗？我需要从java测试应用程序以编程方式运行ffplay，以查看服务的加载

附言：我还尝试添加选项“-nodisp-an”，但这提供了与上面提到的相同的结果。

我也遇到了同样的问题，但用于多播

ln -s /dev/null file
ffmpeg -dn -i udp://@224.224.224.224:1234 -f null file 

这对我很有用，希望有人能帮上忙
