Getting errors with sample codes of media SDk

[vinay_k_1]

Hi All,

I installed mediaSDK2014 for clients on my laptop which has i5-core of 3rd generation with windows7 OS and Visual Studio 2010 SP1 package.

I am getting following errors while building sample decode example. Please help me to find out what i am missing and how do i correct it .

HI,

It seems you are not finding the functions from Media SDK library when linking.

When you installed the "MediaSDK 2014 for Clients" package, it should have created a global environment variable called INTELMEDIASDKROOT.  You may need to reboot your system and/or re-launch Visual Studio for environment to take affect.

If you still have issue, can you open the Property Pages of the "sample_common" project and examine the "Configuration Properties->C/C++->Command Line" that your system is using.

Thanks Tony for your reply.
I tried setting environment variable for INTELMEDIASDKROOT and i can see that it is in environment variable list.
I rebooted the machine and restarted the Visual studio , still no luck with problem i described.
Please help .

Regards

I tried with x64 mode of building the sample code and found one link error:

2>LINK : fatal error LNK1181: cannot open input file 'libmfx.lib'

Not sure, why would it behave differently between win32 and x64 modes.

Regards

After adding libmfx.lib path from x64 folder , i am able to build only in x64 mode.
What should i do to get this built for win32 ?

Please advice.
