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.

yes i have the library. Could it be that the path to it is bad or something.
I tried setting a gst-plugin-path to the folder where it is located but that
didnt help

Hi there! Just wondering if you managed to resolve the above issue? I'm

Thanks!

Hi Bdjukic

To use GStreamer video utilities you need to link in additional libraries. The simplest way is to use pkg-config. Append the following flags to your build process:

VIDEO_CFLAGS=`pkg-config --cflags gstreamer-video-1.0`
VIDEO_CFLAGS=`pkg-config --libs gstreamer-video-1.0`
