AAC-LC on DM-365 not able to encode @ 8kHz, 1 ch configuration

Hi,

I am using DM-365 custom platform with DVSDK version 2_10_01_18. I have downloaded AAC-LC package from TI site and able to integrate with my application.

When I try to configure AAC-LC Encoder at 48kpbs, 8kHz, 1ch, I am getting error from " AUDENC_process()". If I change the configuration to 48kpbs, 8kHz, 2ch, encoding works and I get AAC output.

But when I play this AAC output on a media player like mplayer or VLC, these application shows AAC stream sampling rate at 16kHz.

Can someone please help me with information on following

1) Can AAC-LC Encoder on DM-365 work with 8kHz sampling rate? or default is set to 16 kHz?

2) What is a way to confirm the AAC-LC encoding sampling rate? Is there a way confirm it by checking some header bits in the stream?
