Running CUDA 5 on a GTX 680
The ‘GeForce GTX 680 Whitepaper’ states that the encoder is capable of handling up to 4096x4096 resolution.
I want to produce a video from 2048x2048 monochrome images.
I ran the cudaEncode sample program with the supplied config file 1080p-h264.cfg modified as follows:
2048 //NVVE_OUT_SIZE width 2048 //NVVE_OUT_SIZE height 2048 //NVVE_IN_SIZE width 2048 //NVVE_IN_SIZE height 2 //NVVE_ASPECT_RATIO (0: 4.0f/3.0f 1:16.0f/9.0f 2:1.0f)
When I run the program, the call to NVCreateHWEncoder fails.
I have managed to create a video at 1024x1024.
Do I need to modify other parameters in the configuration file or is the whitepaper incorrect?
