transcoding(one input + two output)

Hi Bjoern,

   Currently i am making the following transcoding scenario below: (one input , two output with different resolution)

                                                                                                    |-> VPP resize to D1 -> D1 encode -> RTP(or FILE)

     RTP(or File)  -> 720P decode -> YUV420 Frame (Video Memory) |

                                                                                                    |-> VPP resize to CIF -> CIF encode -> RTP(or FILE)

    as for upper block ,i have two issues to make sure:

   1.  one decode raw frame can be used by two VPP processor simultaneously , does it work? or any special usage to pay attention by application? 

   2.  i prepare to use three threads to handle upper scenario (except rtp handle), one for 720P decode, the other two for VPP resize and encode. is there any better or simple method to achieve this transcoding session?  any comments are well appreciated! 

Thanks,

Denny
