Hi Simon,
Thanks for the quick response! im getting closer...
So now i understand, its /usr/lib/mediastreamer/plugins
so i have added a few printf's in and around the ms_load_plugins function, one
to print the search path and the other to print the files it finds
my file is called libmslisgw.so
so if i run linphonec i get my debug strings...
It finds my file - but doesnt seem to do anything with it, i thinks it failing
on the strstr calls, possibly the PLUGINS_EXT bit?
root:/usr/lib/mediastreamer/plugins> linphonec
NLS disabled.

by $prefix I meant the installation prefix (usually /usr or /usr/local),
when you do 'make install' in linphone.
thus the plugin should be in
/usr/local/lib/mediastreamer/plugins/
if you configured linphone with --prefix=/usr it will be in
/usr/lib/mediastreamer/plugins/

No need to register the filter if they are instanciated with
ms_filter_new_from_desc (it is only necessary when using ms_filter_new
or ms_filter_new_from_name ).

The MS_FILTER_DESC_EXPORT is empty, it's just a marker for an awk script
in mediastreamer2/src/Makefile.am to collect all descs and automatically
generate a header file with them.

That's ok. Category is just indicating whether the filter is an encoder,
a decoder, or something else.
