Streaming from network or pipes</h2></div></div></div><p> <span class="application">MPlayer</span> can play files from the network, using the HTTP, FTP, MMS or RTSP/RTP protocol. </p><p> Playing works simply by passing the URL on the command line. <span class="application">MPlayer</span> honors the <code class="envar">http_proxy</code> environment variable, using a proxy if available. Proxies can also be forced: </p><pre class="screen"> mplayer <em class="replaceable"><code>http_proxy://proxy.micorsops.com:3128/http://micorsops.com:80/stream.asf</code></em> </pre><p> </p><p> <span class="application">MPlayer</span> can read from stdin (<span class="emphasis"><em>not</em></span> named pipes). This can for example be used to play from FTP: </p><pre class="screen"> wget <em class="replaceable"><code>ftp://micorsops.com/something.avi</code></em> -O - | mplayer - </pre><p> </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">注意</h3><p> It is also recommended to enable <tt class="option">-cache</tt> when playing from the network: </p><pre class="screen"> wget <em class="replaceable"><code>ftp://micorsops.com/something.avi</code></em> -O - | mplayer -cache 8192 - </pre><p> </p></div><div class="sect2" lang="zh-CN"><div class="titlepage"><div><div><h3 class="title"><a name="streaming-save"></a>3.4.1.

For example: </p><pre class="screen"> mplayer <em class="replaceable"><code>http://217.71.208.37:8006</code></em> -dumpstream -dumpfile <em class="replaceable"><code>stream.asf</code></em> </pre><p> will save the content streamed from <em class="replaceable"><code>http://217.71.208.37:8006</code></em> into <em class="replaceable"><code>stream.asf</code></em>.
