Never mind had to add -hw to

Hi
Installed media sdk on base Ubuntu 14.04, with i7-4760HQ, running 3.8 kernel:

# uname -r
3.8.0-23-generic

#clinfo
…

Followed the ./install.sh path, without any problems. After reboot verified correct kmd:

Rebuilt the sample directory without any errors:

Return on error: error code -3, /home/msdk/mdp_msdk-samples/samples/sample_encode/src/pipeline_encode.cpp 947

Return on error: error code 1, /home/msdk/mdp_msdk-samples/samples/sample_encode/src/sample_encode.cpp 439

Any help would be appreciated.
Cheers,

Never mind had to add -hw to the cli, Doh:

Glad you fixed it. The linux versions do not support SW implementation, thus -hw flag is mandatory for running the samples on linux. The help menu for sample applications could be more explicit about this, and give better error messages!
