Video streaming 通过RTP将H.264视频从Live555传输到VLC

如果您能帮助我解决H264流媒体问题，我将不胜感激，这是我数周来一直在努力解决的问题

我需要将H264视频从Live555（在Linux机器上）传输到VLC Media Player（在Windows机器上）使用RTSP时效果非常好，但我需要在不使用RTSP的情况下使用RTP，而使用RTP时我看不到视频。VLC甚至无法识别流是H264

这是通过RTSP传输的SDP文件（有效的配置）：

但是如果我从RTSP切换到RTP，它就不工作了。我已经试着在VLC播放器中加载上面的SDP文件，但是没有帮助

以下是VLC Player 0.8.6d的一些调试输出：

（可能有打字错误，因为我必须手动复制-不要问：））

在VLC 1.0.5中，我得到一个未知有效负载类型错误，由于未知网络堆栈错误，SDP根本无法加载。显示的其他错误包括不支持的SDP连接信息和Sap解复用器警告：无效的SDP

任何帮助都将不胜感激

谢谢,

我要做的是使用SDP文件，而不是直接打开流。结果表明，SDP数据仅在使用RTSP时传输。流式传输RTP时，我必须自己提供SDP文件

所以我所做的是：

使用RTSP（有效的方法）流

使用Wireshark记录通过RTSP传输的SDP文件

将SDP另存为扩展名为.SDP的文本文件

在VLC中，打开SDP文件，而不是直接打开网络流

它变魔术了

一个简短的评论：您的SDP文件在技术上是无效的。您应该使用base-64编码SPS和PPS信息，用逗号分隔，并将其附加到sprop参数集。您将其设置为字符串“H264”，这肯定是错误的（尽管很不幸，这很常见）。也可以通过使用

*env打印SDP内容来实现
