cuvidCreateDecoder failed with CUDA_ERROR_INVALID_VALUE (GT 630, 2032X2032) (resolution over 1080p)

As title, cuvidCreateDecoder failed with CUDA_ERROR_INVALID_VALUE with 4k (3840X2160) video using GT 630. It runs normally with 1080p video. In fact, I’ve tried videos with some resolutions. I found that the resolution below 1080p runs normally, otherwise, it failed with CUDA_ERROR_INVALID_VALUE. I also tried GT 730 and it runs normally with all resolutions. So, I think the decoder of GT 630 might not support resolutions higher than 1080p.

Are there any documents or specifications that I can refer to? Or, how do I know further information about the error CUDA_ERROR_INVALID_VALUE?

Thanks a lot.

Sorry, I updated the Nv decode SDK and found that cuvidGetDecoderCaps can query the ability of decode. I get max decoding width/height of GT 630 is 2032/2032. However, it still failed with CUDA_ERROR_INVALID_VALUE when the resolution of source video is higher than 1080p (e.g. 1920X1440, 1920X1200).

Any hint about this?

Hi.
Can you provide more details related to this failure - which codec, OS and driver version you used.

Hi Godse,

Sorry for the unclear information.

OS: Windows 10
Codec: h264
Driver version: 23.21.13.9135

Another question. Can I use Nv Codec SDK on OS X? I’d like to make a h264 decoder application on OS X. If not, do you know any low-level decode library on OS X?

Thanks a lot.

Hi.

It appears you have a Fermi GPU.
As you correctly found out, cuvidGetDecoderCaps() API can be used to query the decoder capabilities.

I want to point out to the snippet in cuviddec.h from 9.0 SDK

unsigned int            nMaxWidth;                  /**< OUT: Max supported coded width in pixels               */
    unsigned int            nMaxHeight;                 /**< OUT: Max supported coded height in pixels              */
    unsigned int            nMaxMBCount;                /**< OUT: Max supported macroblock count
                                                                  CodedWidth*CodedHeight/256 must be <= nMaxMBCount */

Along with width and height, macroblock count also should be within the limit.
Can you check that is causing problem for you?

Thanks.

Video Codec SDK is not supported on OS X.

Thanks.
