Decode multiple video/audio files (DASH's adaption sets)

[Majaja]

Dear all:

I had a problm about DASH (in fact, even local file playback & if the file
has multiple video or audio tracks) and would like to ask for your help.

The problem is, for my application, I have an unique Video/Audio decoder HW
instance and they both DONOT support multi-thread usage. So they can only
decode a sinle stream at one time. 
Once we create multiple instances for, ex video. It will lead to system
crash.

Please refer to the following link:

The graph dump for this URL is as the link below.

You can find that there are two audio adaption sets there, one for English
and the other for Italian. 

It makes playback fail here as the description above.

If we use software CODEC which supports multiple decoding threads, I think
it will be O.K.

I believe there may be somebody who has the same problem with me, since for
embedeed system applicaiton, it is a comman case to allow decode an unique
stream only at a time.

DO you have any suggestion for this issue or has thers had an existing
solution already?

Thank you
