Description Jeremiah Rose 2010-02-25 06:38:37 UTC 
Using a Python script that dynamically plugs new bins into a single adder, without leaving the PLAYING state. 

It does this indefinitely, swapping in new bins whenever the old ones expire (i.e, reach EOS). The result is a continuous, layered stream of sound, from various file sources.

Each time a new bin is linked to the adder, a request pad is obtained, with name sink%d. The integer %d increases rapidly as the program runs; many bins are added and removed.

When %d reaches anywhere above 100 (has gotten upto 600 before), I eventually get this error:

(slurry.py:3365): GStreamer-WARNING **: pad adder:sink115 has no event handler, file a bug.

So here I am, filing a bug.

I suspect the problem could be avoided by re-using previous request pads instead of getting new ones. They are being released, but not reused. Regardless, there shouldn't be upper limits!

If any more information is required, I am happy to oblige.

Could you attach a sample script which reproduces this bug? It should be impossible to get a new sinkpad from adder without an event function...

Jeremiah, have you had a look at
tests/examples/dynamic/sprinkle*.c
Those examples imho do the very same thing and run fine.
