[gst-devel] My First Plugin - Help please

[Ionut Dediu]

Just wanted to point out that the docs are really scarce on beginner specific information. (please don't refer me to the 2 official manuals). Btw, every mature technology acknowledges itself by providing at least one printed book on the subject. While there are dozens of books about DirectShow NOTHING is available yet for gstreamer. Could we (hello worlds out there on gstreamer) hope to see a Gstreamer book any time soon? If not a "for Dummies" kind of book, at least a GStreamer Internals explained.
Thanks,
Ionut

Cool,
That solved that issue.  The problem now is that it does not show up as a
plugin at all.
using gst-inspect to list plugins.

I cannot work out when I should use BOILERPLATE_FULL and when I should use
GST_PLUGIN_DEFINE and gst_element_register as I cannot get a
GST_BOILERPLATE_FULL and GstVideoSink to register.  
Am I missing something really obvious? The manual is a bit vague at this point
and any help would be appreciated.

You need to link to libgstbase-0.10.so in addition to
libgstreamer-0.10.so. Add gstreamer-base-0.10 to your pkg-config module
list (or the PKG_CHECK_MODULES in configure.ac).

You can also check with ldd -r /path/to/your/libgstMyFramedVideo.so.

Cheers
