Hi,

I just pushed a fix to gst-template for what it's worth, the plugin
name for the audiofilter example wasn't right:

https://gitlab.freedesktop.org/gstreamer/gst-template/commit/16d996b0efc3643323698e986f33a1753cb00f15

The source filenames don't matter, the two things that need to match
are: 1) the plugin .so/.dll filename and 2) the plugin name in
GST_PLUGIN_DEFINE (third argument).

Cheers
