decoder h264 with cuda

I search a solution to decode multi h264 files
I’ve tried with vdpau and mplayer patch for vdpau (pureVideo)
It works very well, but it is restricted to decode only one video at a time.

Do you have any ideas for decode simultaneously 2 HD (1920x1080) et 8 SD (720x576) h264 high profile


I am looking for help with using vdpau for decoding H264. Do you know someone who I can collaborate with?
