CUDA 3.2 H264 Encoder

I’m using CUDA 3.2 to create a H264 encoder using NVCreateHWEncoder().

It seems to fail when I specify a resolution greater than 1080p in the input parameters.

Does the encoder support resolutions greater than 1080p?

Somewhere I heard that NV CUDA SDK for encoding h.264 stream not supporting frames under 720p… But… Do You REALLY need more than 1080p (FullHD)? What for? It’s just interesting to me. But possibly I can help You with any ideas)
