Comment 1 Ronald Bultje 2004-12-13 18:09:53 UTC

Adder has some invalid stuff in its loop function. It does a single peek(), then
breaks out of the loop if that gives an event (which all streams start with...)
and then checks if width != 0. Problem is that some formats only set format
(width) at runtime.

The loop in adder needs some fixes. All the rest (your g_malloc() failure, but
also the width = 0 warnings and everything) is a consequence of this, I think...

Comment 2 Ronald Bultje 2005-01-03 17:51:26 UTC

*** Bug 162704 has been marked as a duplicate of this bug. ***

Comment 3 Ronald Bultje 2005-01-03 17:56:43 UTC

So with Miron's bug dup'ed, this isn't only in adder anymore. Audioscale needs
some smartness in resampling, it shouldn't resample empty input. I'll poke
around with this soon.

Comment 4 Ronald Bultje 2005-03-01 17:32:08 UTC

Fixed...
