FATAL: get_bits failed : No backend implementation could be loaded.!!
There's some problem with your build.
That message is normal, just a function we haven't implemented yet.
As far as I can see it's actually illegal API usage in qvdpautest. It's trying to read from uninitialized video surfaces, which is not guaranteed to work. Swapping around the order of tests so that it does the PutBits test first fixes it.
