audioresample assertion failed: (out_len >= out_processed)

Fri Jul 8 09:51:33 UTC 2016

Hi,

i have a issue with an assert in audioresample (1.8.1).
ERROR:gstaudioresample.c:1125:gst_audio_resample_process: assertion failed:
(out_len >= out_processed)

In my pipeline i implemented a BUFFER PadProbe on the audioresample sink and
source pad.
Within that callback, i like to change the caps rate (norminal 48kHz +-
50Hz).
Unfortunately after some frames, my application stops with the assert.
I attached a pdf file with the debugger backtrace and the local variables.

Do you have any hint?

Maik
