How to Troubleshoot GStreamer
The GStreamer multimedia framework used on the Linux operating systems is designed for processing and playing back various audio and video formats on other media programs. The framework consists of an application and a series of plug-ins that vary depending on the installation package used. The plug-ins are used in conjunction with other audio/visual programs to stream and play back music and video. The troubleshooting process for this framework is relatively quick and straightforward.

Open a "Terminal" screen and type "gst-inspect [plugin]" into the prompt, if the application reports that the plug-in is missing. Replace the "[plugin]" phrase with the name of the missing GStreamer plug-in. If the command fails to locate the plug-in, use the built-in application library within Linux to locate, download and install the required plug-in.

Recompile or reinstall the GStreamer if you receive a "(process:26626): GLib-GObject-WARNING" error. If you run GStreamer from "git" uninstalled, enter "make clean && make" into the "Terminal" prompt. If you installed GStreamer from an installation package, remove all instances of GStreamer and reinstall the program using Debian or RPM packages, if possible.

Recompile the GStreamer application and plug-ins without any optimization flags if the program stops due to a segmentation fault. Perform a "backtrace" by typing "gdb," followed by the name of the GST application into the "Terminal" prompt. Enter "set args" at the "(gdb)" prompt. Type "run" at the next prompt and wait for the application to generate another segmentation fault. After the fault, type "bt" into the prompt to create a backtrace log. This log is useful for tracking down code faults related to the application and plug-ins.
