GStreamer Daemon - Troubleshooting
This wiki show how debug a pipeline using the debug enable.
Contents
Debug Log
Gstd redirects its own and any GStreamer log to a folder named gstd, created at /usr/local/var/log. There you can find "gstd.log" and "gst.log":
- /usr/local/var/log/gstd/gstd.log: Contains GStreamer Daemon debug messages.
- /usr/local/var/log/gstd/gst.log: Contains all the Gstreamer log messages (including debug).
You can also change the gst.log and gstd.log file path when you launch gstd:
1 gstd --gstd-log-filename /home/nvidia/gstd.log --gst-log-filename /home/nvidia/gst.log
Debug Enable
To debug a pipeline one easy way is to enable the debug using gstd, next examples show how to do it, and what is the expected output when some works good or fail.
1 pipeline_create p1 videotestsrc ! autovideosink
2 pipeline_play p1
3 debug_enable true
4 debug_threshold 6
5 debug_color true
6 pipeline_create p playbin uri=file://tmp/video.mp4
7 pipeline_play p
You can enable debug for specific elements:
1 debug_threshold *videotestsrc*:5 #set the debug level on all videotestsrc elements to 5
2 debug_threshold videotestsrc1:6 #set the debug level on videotestsrc1 to 6
You can find more info about GStreamer debug levels here: https://gstreamer.freedesktop.org/documentation/tutorials/basic/debugging-tools.html
