GStreamer 上的“列入黑名单”是什么意思？

我正在尝试交叉编译 GStreamer。版本是1.2.3。主机PC的操作系统是x86 linux，目标系统的操作系统是MIPSEL linux操作系统。

我成功为目标设备编译了 gstreamer 和插件。和gst-launch-1.0可以被执行。所以我尝试使用基本插件 libgstvideotestsrc。但这没有用。所以我运行“gst-inspect-1.0”来检查插件，然后我发现了如下结果。

# gst-inspect-1.0 -b

我想知道“黑名单”的含义以及我应该如何解决这个问题。如果您需要一些信息来解决此问题，请告诉我。

这是我的 GStreamer 构建配置。

如果你想确切地知道为什么这些插件被列入黑名单，你可以删除“registry.dat”（运行locate以找出其位置），然后重新运行gst-inspect，这些插件将再次被检查以及将它们列入黑名单的原因应打印。

他们被列入黑名单的原因可能有多种，如果您这样做，您应该找出他们。

或者，您也可以运行 gst-inspect location_of_the_dynamic_library.so
