That's normal and expected in this case, that ::create() is
blocking/waiting on something for data to be available. Usually that
would be blocked on a file descriptor / socket / handle or a GCond
though.

It sounds like you might want something like appsrc, where you just
call gst_app_src_push_buffer() whenever you have a new buffer
available. (Appsrc will add this to an internal queue and then signal
on a GCond to wake up the ::create() function thread if it's waiting
for a new buffer).

Cheers
 Tim
