AMRNB decode crash

[Jacky_C_2]

Hi,

I am using the IPP 8.2.3 speech coding lib and USC interface for AMRNB decoder. The decode process crashed.

Here is the gdb infos.

I checked the memory bank allocation, all memory were allocated normally. How can I troubleshoot it?

Jacky, 

Are you doing some evaluation on the IPP legacy speech codec samples, or were they used in your project before?  You may notice,  the speech codec and the high level USC sample code was deprecated before.   please check if the deprecated code may meet your request. 

For the error, the apiGSMAMRDecode()functions is in the USC source code of the legacy sample code. Did you add some debug option to build these source code, and see if it can debug form the source on see where the code reports crash.

Thanks,
Chao

Hi Chao,

Thanks for your reply! 

Yes, I never used it in the project before. I just installed the IPP product and got the binary libs from the installation directory. Without the source code, it's hard to add debug info in that function. I checked from the high level invoking, seemed nothing abnormal.

Does it effect if I am using the legacy samples? But I notice from the release note. In IPP 8.2, these speech coding samples were just deprecated, not total removed. Is there any difference from it was been deprecated?
