Hi all,<br> I was going through the Plugin writers guide, and I sincerely feel that the <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/chapter-building-testapp.html">chapter 9</a> should also describe how to build the test plugin "my_filter"<br>
that was described all the way along and also being used in the test app. BTW, I used the following command to do this,<br><span style="font-family: courier new,monospace;"> gcc `pkg-config --libs --cflags gstreamer-0.10` gstexamplefilter.c --shared -o ~/.gstreamer-0.10/plugins/libexamplefilter.so</span><br>
<br> But was unable to load it, <br><br> I got the following error message, when I ran it through valgrind :<br><br style="font-family: courier new,monospace;"><div style="margin-left: 80px;"><span style="font-family: courier new,monospace;">==3068== Memcheck, a memory error detector.</span><br style="font-family: courier new,monospace;">
