[Problem] About multiple CUDA decoder limitation

Dear all,

By modifying the decoder in CUDA SDK,
I had wrote a program to decode multiple video in the GPU.
And I can also get the correct result after decoding.

When I create more then 10 decoders,
the CUDA respone an error about creating fail.
It happened at two functions call :

hr=cuGLCtxCreate(&hContext, CU_CTX_BLOCKING_SYNC,hDevice); -> hr = 999

or

hr=cuvidCreateDecoder(&hDecoder,&info); -> hr = 300

I don’t know why this happended.
Cause I get different count of decoder in different computer with the same GPU.

Does anyone have idea of this issue ? :confused:


My Environment

OS : Windows 7
GPU : GTX 260
Driver : 257.21 (CUDA version 3.0)
