[gst-devel] amr-wb seek problem

[Jorney_dong]

Thanks for everyone's help!
I have got the issue fixed, it's the amrwbdec:

just add one line in the amrwbdec.c of
gst-plugins-ugly-0.10.16.

288: if (!block || gst_adapter_available (amrwbdec->adapter)<  block)
      + {
      +  gst_adapter_clear (amrwbdec->adapter);
       break;
      + }

Because when there are incorrect data, if you don't clear it, the next checking
is still incorrect.
