However， I had installed OpenCL successfully:

/opt/intel/opencl/libOpenCL.so
/opt/intel/opencl/libOpenCL.so.1.2

Have I done something wrong? Can anyone help me? Thanks~

Hi there, 

Can you tell us which OS you are working on? Can you please confirm if you went through software requirements from the samples guide which advice to install gcc compiler and also the build instructions from the sample guide?

Thanks,
Surbhi

Hi~

My OS is CentOS 7.1, and I have built instructions from the sample guide. (\MediaSamples_Linux_6.0.16043175.175\Media_Samples_Guide.pdf)

Besides, we bought 4 Intel's server with the same configuration. I installed and run this sample successfully on one of them, and this error:

"/home/MediaSDK_R6/MediaSamples_Linux_6.0.16043175.175/samples/sample_plugins/rotate_opencl/include/opencl_filter_va.h:25:23: fatal error: CL/va_ext.h: No such file or directory
 #include <CL/va_ext.h>
                       ^

"

should not be occured.

althouth I have just solved this error by add include path on $PATH.

And it is, this error "solved", but when I run sample_decode_drm, another error occured:

It's so weird...

Hi, Have you upgraded your KMD ? You can use following command line check your KMD $ uname -r $ ls -l /dev/dri ## You should find renderD128 if KMD is OK. You can refer Page 3 Getting Started Guide - Linux* Installation to upgrade KMD. https://software.intel.com/sites/default/files/media_server_studio_getting_started_guide.pdf Thanks Zachary

I have solved this problem by

#rpm --force -Uvh /MSS/rpmbuild/RPMS/x86_64/*.rpm

although I don't know why ...

 even more puzzling is:

both

.../MediaSamples_Linux_6.0.16043175.175/samples/_bin/x64/sample_decode_drm

and

.../MediaSamples_Linux_6.0.16043175.175/samples/__cmake/intel64.make.debug/__bin/debug/sample_decode_drm

get the same results(same fps...), it's seemed that MediaSamples_Linux_6.0 generate useless, why is this happening?

Glad, you got that part working!
Not sure why would you expect same sample to generate different results, but sample_decode_drm in the above pointed location is being generated from same sample. Can you please explain your expectation?

(Well, I'm hammering at OpenCL study recently...)

Since get the same result, so why we should build samples following  …\MediaSamples_Linux_6.0.16043175.175\Media_Samples_Guide.pdf? Why don’t we use the …\MediaSamples_Linux_6.0.16043175.175\samples\_bin\x64\*drm directly?
