undefined symbol: gst_dmabuf_allocator_new

[GStreamer-devel mailing list]

Hi

I use plugin bad template to construct my custom element,

https://developer.ridgerun.com/wiki/index.php?title=Creating_a_New_GStreamer_Element_or_Application_Using_Templates

I try to use gst_dmabuf_allocator_new() function but when I use
gst-inspect-1.0 to check, it shows undefined symbol.

My element is based on GstElement.

GObject
 +----GInitiallyUnowned
       +----GstObject
             +----GstElement
                   +----GstMyFilter

How to add dma buf support on my element?

Thanks a lot.

To use this API, you need to link against gstreamer-allocators-1.0 library (this
is pkg-config name for it).

While the API is always there, having "support" for it requires Linux of course.
