在 gstreamer 中禁用调试日志？

Question

我正在运行gstreamer in docker 和GST_DEBUG 可以用来打开额外的调试日志，但是即使我设置了GST_DEBUG=2 或GST_DEBUG=3，那么仍然会出现几个DEBUG 日志。这是一个例子：

如何关闭这些功能？

Answer 1

问题在于kvssink 插件，它有自己的日志记录设置。可以使用配置文件和log-config 设置该文件的路径（see here）

Answer 2

你究竟是如何设置这个变量的？我通过导出它多次使用它：export GST_DEBUG=3，它可以正常工作。有关如何以编程方式使用它的信息，请参阅此链接：https://gstreamer.freedesktop.org/documentation/gstreamer/gstinfo.html?gi-language=c。
