如何查看gstreamer调试输出? [英] How do I view gstreamer debug output?

问题描述

如何查看GST_CAT_INFO，GST_DEBUG等功能的输出? 我需要使用调试级别集自己编译gstreamer还是可以在应用程序级别完成编译?

How to view the output of functions like GST_CAT_INFO, GST_DEBUG etc? Do I need to compile gstreamer myself with debug level set or it can be done at application level?

推荐答案

可以使用GST_DEBUG环境变量在stderr中打印调试消息(如果gstreamer已使用--enable-gst-debug编译，则为默认设置).

Debugging messages can be printed in stderr by using the GST_DEBUG environment variable (if gstreamer has been compiled with --enable-gst-debug, which is default).

例如:GST_DEBUG=audiotestsrc:5 gst-launch audiotestsrc ! fakesink将记录来自audiotestsrc元素的所有内容(5).

For example: GST_DEBUG=audiotestsrc:5 gst-launch audiotestsrc ! fakesink will log everything (5) from the audiotestsrc element.

您可以使用setenv("GST_DEBUG","cat:level...", 1)
