GStreamer Debug Emacs Module


gst-debug.el is an emacs mini module to navigate GStreamer debug logs.

When hitting Enter or M-. in a log file it will open the source code to the line that generated that debug message. If you have multiple emacs windows open, it will open the GStreamer source code file in the second to last active so you can continue reading the log in the active window. If you only have one window open it will open the source code file in the current one.


You need a recent Emacs to use latest helm, at least Emacs-24.3.

Getting Started


  1. Get gst-debug.el into your emac's load path
$ git clone https://github.com/luisbg/emacs-gstreamer.git
$ cp emacs-gstreamer/gst-debug.el ~/.emacs_load_path/
  1. Add it to your emacs init file (usually ~/.emacs)
(require 'gst-debug)


(add-to-list 'load-path "/path/to/emacs-gstreamer/directory")
(require 'gst-debug)


First you need to generate and load your tags table since gst-debug depends on it.

$ cd /path/to/gst/modules
$ etags `find . -name "*.c" -o -name "*.h"`
M-x visit-tag-table TAGS

Open in emacs the Gstreamer debug log file generated without colors and switch to gst-debug mode.

Enter or M-. will jump to the source code line where the log line comes from.

For example:

$ gst-app --gst-debug=*:5 --gst-debug-color-mode=off &> gst_log
M-x find-file gst_log
M-x gst-debug
M-x goto-line 100
