The example code in GStreamer Basic Tutorial available at https://gstreamer.freedesktop.org/documentation/tutorials/basic/short-cutting-the-pipeline.html is returning the following compile error:


basic-tutorial-8.c: In function ‘main’:
basic-tutorial-8.c:172:11: error: ‘audio_caps_text’ undeclared (first use in this function); did you mean ‘audio_caps’?
   g_free (audio_caps_text);
           ^~~~~~~~~~~~~~~
           audio_caps

The solution seems to be simple to delete the affected line as there is no audio_caps_text to be freed at all.

After removing this line the codes runs without problems.
