problem with CUDA video decoding example

Accelerated Computing CUDA CUDA Programming and Performance

I tested H.264 video decoding with CUDA SDK example. It is quite fast. However, the decoding gives some bugs (wrong blocks on the picture) when number of reference frame is equal to 5. Furthermore, if this number is greater than 5, the display is nothing but a black screen.

Have you also experienced such case? Is there some explanation about this bug?

Most likely H.264 level 4.1 restriction.

Current driver currently limits support to High Profile level 4.1. Support for level 5.1 streams should be added in a subsequent driver.

Thanks a lot, Sulik and Paulius.
