如何找到所需的 GStreamer 插件？

Question

我正在尝试使用 URL

https://rtvelivestream.akamaized.net/rtvesec/rne/rne_r3_main.m3u8

播放网络广播。我可以使用

wget

下载播放列表并获取媒体 URL，但是当我尝试使用

gst-play

播放它时：

$ gst-play-1.0 https://rtvelivestream.akamaized.net/rtvesec/rne/GL0/37_2023_03_28_09_53_51_85364.ts
Press 'k' to see a list of keyboard shortcuts.

尽管它与

mplayer

一起工作，所以 URL 和媒体是正确的：

$ mplayer https://rtvelivestream.akamaized.net/rtvesec/rne/GL0/37_2023_03_28_09_53_51_85364.ts

我已经安装了所有的gstreamer插件包，但仍然没有快乐

$ apt list gstreamer*-plugins*

如您所见，这是 Ubuntu 22.04。相同的命令适用于 18.04 的旧盒子......那么插件是否已被删除？我可以在其他地方找到它吗？我怎么知道哪个插件在哪里？
