Package: speex
Version: 1.2~beta2-2
Severity: important
The preprocessor API has been updated in 1.2beta2, and it seems
buggy to me. Both SPEEX_PREPROCESS_GET_PROB_START and
SPEEX_PREPROCESS_GET_PROB_CONTINUE only returns either 0 or 32767.
I'm including a small test program which results in the following
output which doesn't look correct for version 1.2~beta2-2:
speex 1.1.12-3
--------------
$ ./speex_preprocess
OK: Prob start 30
OK: Prob continue 7
speex1 1.2~beta2-2
---------------------
./speex_preprocess
ERROR: Prob start 32767
ERROR: Prob continue 32767
