Big Problem With H.264 and Mpeg4 from TI decodeCombo.x64P

Hi all,

I've extend the demo decode to support two channel decoding. 

I tried to open two instances of decode algorithm in the same codecengine.

when the to algorithm created with the follow sequences, works fine.

1. open two h.264,                                 OK
2. open two mpeg2,                               OK
3. open two mpeg4,                               OK
4. open mpeg2 first, then mpeg4        OK
5. open mpeg2 first, then h.264          OK
6. open mpeg4 first, then mpeg2       OK
7. open mpeg4 first, then h.264         OK
8. open h.264 first, then mpeg2         OK

But when I tried to open h.264 first, then mpeg4, it seems that the open is OK. But nothing will be decoded, and the DSP usage is 0% always.

Any idea?

Please!!!!!!!!!!!!!!!

Yours David Chan
