Question

我无法弄清楚如何从VLC播放RTMP流。我可以通过Flash播放器在网上查看它没有问题。我通过firebug找到了关于流的信息：

<data>
  <smilRoot>
    <body>
      <switchItem id="0-BO-18166" base="rtmp://wcdn101.nacevi.cz/ct-vod/_definst_?id=HRr8GUgv1FcCBzw1-01&amp;publisher=lss" begin="0" duration="134" clipBegin="0" type="recorded" stat="ProjectId=3;ApplicationId=4;NodeId=9">
        <video src="mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_720p.mp4" system-bitrate="3500" label="720p" enabled="true" />
        <video src="mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_576p.mp4" system-bitrate="2000" label="576p" enabled="true" />
        <video src="mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4" system-bitrate="1000" label="404p" enabled="true" />
        <video src="mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_288p.mp4" system-bitrate="500" label="288p" enabled="true" />
      </switchItem>
    </body>
  </smilRoot>
</data>

我试图使用rtmpdump，vlc及其组合播放404p流。我不太确定如何粘贴URL，但我尝试了所有我能想到的组合。我试过的一些例子：

rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss/mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4
rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss?mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4
rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss/?mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4
rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss/iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4
rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss?iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4

这是rtpdump所说的：

$ rtmpdump -v -r "rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss/mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4"

VLC不断抛出错误：

[00007f7918008088] avio access error: Failed to open rtmp://wcdn101.nacevi.cz:1935/ct-vod/_defins.t_?id=HRraUUgv1FKF42a-02&publisher=lss/mp4:iVysilani/2014/10/08/KristynaLiskaBokCT-081014-MP4_404p.mp4: Unknown error 833925547

顺便说一句，我用wireshark嗅探了RTMP数据包，通信看起来像这样：

我确信我做错了什么，有人能给我一个如何播放这个流的提示吗？

Answer 1

我一直想用VLC播放RTMP流而没有成功，并且得到了和你一样的错误。

Unknown error 833925547

以及rtmpdump我也得到ERROR: Closing connection: NetStream.Play.StreamNotFound

我使用的是VLC 2.1.6，它附带了Ubuntu 14.04和相应版本的rtmpdump。

所以，碰巧我把rtmp url给了一个使用Windows操作系统的朋友和一个使用Mac OS的朋友。他们都没有问题地打开我的网址。

VLC可能会在Linux上使用一些被破坏的后端（即rtmpdump）。

我想我必须为VLC提交一个错误，我确实将Ubuntu 14.04中的2.1.6 VLC升级到2.2.1 - 它再次无效。我自己尝试了一个Windows（2.2.1），它打开了！

到目前为止，我目前的状况如下：

    Ubuntu 14.04 
    VLC 2.1.6 - CANNOT OPEN the rtmp that I provide (myself)
    VLC 2.2.1 - CANNOT OPEN the rtmp that I provide (myself)

    Windows
    VLC 2.1.5 - OPENS WITHOUT PROBLEM the rtmp I provide (my friend)
    VLC 2.2.1 - OPENS WITHOUT PROBLEM the rtmp I provide (myself)

    Mac OS
    VLC 2.2.1 - OPENS WITHOUT PROBLEM the rtmp I provide (my friend)

如何在VLC中打开RTMP流？
