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.

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?
