Did you notice the inline comments in the GstRingBufferSpec structure? You
can find those here:
I'm a bit surprised that segtotal = 1 doesn't produce a warning or error.
The smallest meaningful ring buffer configuration is with two segments,
where one can be in use by the writer (upstream) and the other one by the
I'm not sure about apex, but I have the feeling it might make more sense to
look at pulsesink instead of alsasink for reference.
