Can I create video/audio/speech decoder twice?

Hi Guys,

I'm build a video conference system.

You know that with codec engine, if we wanna decode a video stream, we should do like below after engine opened.

/*create the video decoder*/

hvd2=Vdec2_create(hEngine, envp->videoDecoder, params, dynParams);

My question is :

         Can I call Vdec2_create twice to have two handle to decode two deferent video streams.

Thanks
