[gst-devel] GStreamer / C++ example ?

[Christian Fredrik Kalager Schaller]

Hi Fabien,
Be also aware that appsink/appsrc are still in-development elements and
might change API/ABI as they mature. Once they are considered ready they
will be moved to gst-plugins-good. 

Any comments about the current API etc. you might add to:
http://bugzilla.gnome.org/show_bug.cgi?id=413418

The more people comment/test those elements the quicker we can declare
them API stable and move them.
