Hi all!

I've compiled gst-plugins-good-0.10.31 from source and when I try to run a
pipeline with 'v4l2sink' I get:

(gst-launch-0.10:1327): GStreamer-WARNING **: External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. If you are running an uninstalled GStreamer setup, you might need to update your gst-uninstalled script so that the GST_PLUGIN_SCANNER environment variable gets set.

(gst-launch-0.10:1327): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstvideo4linux2.so': /usr/lib/gstreamer-0.10/libgstvideo4linux2.so: undefined symbol: gst_v4l2sink_get_type

Looking in the code I only see:

$ grep -r "gst_v4l2sink_get_type" *
docs/plugins/gst-plugins-good-plugins-sections.txt:gst_v4l2sink_get_type
sys/v4l2/gstv4l2sink.h:  (gst_v4l2sink_get_type())
sys/v4l2/gstv4l2sink.h:GType gst_v4l2sink_get_type(void);
Binary file sys/v4l2/.libs/libgstvideo4linux2_la-gstv4l2object.o matches
Binary file sys/v4l2/.libs/libgstvideo4linux2.so matches

It seems that the symbol is defined in 'gstv4l2sink.h', but anybody knows where this method is implemented?

Regards,
Jorge
