The flash is utterly bad with GStreamer backend...
As you have already been reported at GNOME bugzilla (*1), it's an issue
of GstAdder. I think so too. I investigated about GStreamer itself for a
while, but it is very complicated.
So, I have an idea for avoinding this adder issue. The idea is that
creating multiple pipeline instead of using adder. I modified the sample
code that you posted at GNOME bugzilla to use multiple pipeline, it
seems to work fine. I attach the modified somple code.
I am not sure whether creating multiple pipeline causes some side effect
or not, but I will try to apply the way to Gnash.

Thank you,
