Is one source AAC-LC (standard AAC) and the other HE-AAC v2 (AAC+)?

There are three variants of AAC:

AAC-LC
HE-AAC (= AAC-LC with SBR)
HE-AAC v2 (= HE-AAC with parametric stereo), aka AAC+

Check your encoders.

You also have to match all other settings, eg. sample rate.

Hi Paul,

Thank you for the information. I already try a player to discover the stream
type of both streams if the are the same.
But i can not find out, so i must check the encoders by my self.

First I wil try one pc encoder to stream to both mountpoint so i am sure the
encoder are the same aac type en bitrate.

I will keep you informed of the result

Best regards, 
Michel

Hello. I have same problem, and I think that it's because AAC+ uses VBR and
when it's changes, is not the same bitrate, because varies...
