我有一件奇怪的事情，我在RTSP服务器上添加了3个不同的媒体工厂。其中一个(下面的第三个(我只能在另一台机器上玩gst启动。
下面的前两个在vlc和gst发布上运行良好，我不明白的是为什么第三个不起作用，所有管道只有不同的源，编码和depay在所有3个管道上都是相同的。
使用vlc和gst启动其他机器。

在其他机器上使用VLC和gst启动

仅在gst启动的其他机器上工作

在我的GST-rtsp服务器实例上使用GST_DEBUG=1时，当我尝试使用VLC:时，它会在最后一个管道上返回错误

我该怎么解决这个问题？
首先，您应该检查VLC日志中不喜欢的内容。由于您的上一个有更多的输入，我可以想象您的合成器有不同的配置。
出乎意料的是，我猜在你的上一个中，合成器输出4:4:4的数据，并创建4:4:4配置文件H.264流。玩家很少支持这些流。
如果是这种情况，您应该确保4:2:0格式进入x264enc，或者在输出上限上定义非4:4:4 H.264目标配置文件。
