I am using the Qt GStreamer wrappers and trying to create a pipeline as follows:
QGst::ElementPtr bin =
QGst::Bin::fromDescription("videotestsrc ! videoscale ! video/x-raw,width=100,height=100");
However, when I run this, I get the error:
GStreamer-CRITICAL **: gst_bin_add: assertion 'GST_IS_ELEMENT (element)' failed
terminate called after throwing an instance of 'QGlib::Error'
what(): no element "video"
I think that there is some issue with the "/" but not sure how to fix it.
The gstreamer pipeline with:
gst-launch-1.0 -v videotestsrc ! videoscale ! video/x-raw,width=100,height=100 ! xvimagesink -e --gst-debug-level=3 sync=false
works fine.
