GStreamer Log Viewer is a tool designed to efficiently handle the voluminous debug logs produced during GStreamer debugging sessions. It aids in navigating, categorizing, and analyzing the debug information, making the debugging process smoother and quicker. GStreamer's debugging system generates detailed logs that can be overwhelming; this viewer makes it easier to manage and understand these logs.

To get a debug log file, set environment variables as below:

• export GST_DEBUG_FILE=gst.log
• export GST_DEBUG_NO_COLOR=1
• export GST_DEBUG=5

See Running GStreamer Applications for details.

• Open Log Files: Easily accessible through the Application menu to open and view logs.
• Visual Timeline: Logs are displayed in a table format with a visual timeline on the left, enhancing the ease of understanding log sequences.
• Filtering Options: Filters can be applied in the filter box when enter key is pressed. Column-specific filtering can be done with the format column_name:search_keyword. Unless column is specified, keywords work for Message column
• Find Functionality: Users can find word through the logs using the find box by entering text and pressing enter to jump.
• Double-click on:
  • Timestamp : open the line in an externally configured text editor
  • Process, Thread, Level, Category, Source, Function, Object : add [column name]:[current value] to the filter box and apply it
  • Line : open the source code and jump to the corresponding line in an externally configured text editor
  • Message : add current message to the filter box and apply it
