* ext/snapshot/Makefile.am:
* ext/snapshot/gstsnapshot.c: (gst_snapshot_sinkconnect),
(gst_snapshot_chain):
* ext/snapshot/gstsnapshot.h:
This has to be a joke... Snapshot should be connected to a tee,
colorspace element before it and EOS after that, where the other
src of the tee receives normal data.
The current way is *wrong*.
