how do I decode mutiple H.264 video streams simultaneously by using OpenMax IL infrastructure?

[Nicolas Dufresne]

This of course would be better if you ask the Bellagio developers. The
OpenMAX IL stack found in Raspberry Pi and Android do have complex
threading mechanism and do support multiple instances. On GStreamer
side, all we do is try and interface this through gst-omx. Note that
there exist hardware where there is only 1 decoding instance.

cheers,
Nicolas
