I tried running the sample CUDA .cu alone and it works just fine and the same with OpenCV. But when i run both together i get these errors. 1> Generating Code... 1>new_stitching_gpu.obj : error LNK2001: unresolved external symbol threadIdx 1>new_stitching_gpu.obj : error LNK2001: unresolved external symbol blockDim 1>new_stitching_gpu.obj : error LNK2001: unresolved external symbol blockIdx 1>C:\Users\UVSS\Desktop\new_stitching\x64\Debug\new_stitching.exe : fatal error LNK1120: 3 unresolved externals 1> 1>Build FAILED. i have added all the library and the include directories correctly. How do i solve this? Thank You very much! G9!
2015-01-20 08:12:07 -0600	asked a question	Problem about Opencv-BT878 resolution! Hello everybody. I New to the forum here, I have a program I need to use for video editing (Glmixer) compiled with opencv 2.4 running on Debian Squeeze. I get good video resolution with my Logitech web-cam, but the display resolution with the capture cards is a whopping 48X32 pixels..! How do I get into opencv to set the resolution higher? I know very little about opencv other than all that code just causes me mass confusion. I read some info on the BT878 cards needing the CVS version, yet I do get output, just lousy resolution. The resolution is fine on everything in Guvcview and Cheese. Thank's a lot! Author: internet việt nam
