basic-tutorial-13.c doesn't compile
I opened https://gstreamer.freedesktop.org/documentation/tutorials/basic/playback-speed.html?gi-language=c , then I copy-pasted basic-tutorial-13.c and tried to compile it. I got (on recent debian sid):
# gcc basic-tutorial-13.c -o basic-tutorial-13 `pkg-config --cflags --libs gstreamer-1.0`
basic-tutorial-13.c: In function ‘send_seek_event’:
basic-tutorial-13.c:21:52: error: incompatible type for argument 2 of ‘gst_element_query_position’
