VLC 不适用于 gst-rtsp-server 具有相同编码和 depay 的 3 个管道之一
VLC doenst work on 1 of 3 Pipelines with same encoding and depay from gst-rtsp-server
我这里有一件奇怪的事，我有 3 个不同的媒体工厂添加到我的 RTSP 服务器。其中一个（下面第三个）我只能在另一台机器上玩gst-launch。
下面的前两个在 vlc 和 gst-launch 上工作正常，我不明白为什么第三个不起作用，所有管道只有不同的来源，编码和 depay 在所有 3 个管道上都是相同的。
使用 vlc 和 gst-launch 在其他机器上工作。

我该如何解决这个问题？
首先你应该检查 VLC 日志它不喜欢什么。由于你的最后一个有更多的输入，我可以想象你的合成器有不同的配置。
出乎意料，我猜想在你的最后一个合成器中输出 4:4:4 数据并创建一个 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 或在输出上限定义非 4:4:4 H.264 目标配置文件。
