undefined symbol in custom plugin(gst_video_filter_get_type)

[dpw157]

Hey all,

I have been trying to get my custom plugin working with gstreamer. I have
been able to get the example myfilter plugin working and registered within
gstreamer. But the one that i wrote that inherits from gstvideofilter does
not work. The error that occurs is  ": src/.libs/libvideoelement.so:
undefined symbol: gst_video_filter_get_type". From my understanding this
should have been auto generated by the G_DEFINE_TYPE() of gstvideofilter and
included within my own file when i did #include
<gst/video/gstvideofilter.h>.

Any help would be appreciated, i am just trying to understand and learn how
to make my own plugins. Thanks for taking the time to look at this post.
