maybe our sample_decode binary is mismatch your build one, Could you help to
copy the sample_decode bin from your build folder:
cd MediaSDK/__cmake/intel64.make.release/__bin/release/sample_decode?

or Is it possible to give your ip address, i can check the env by remote.

and i will also offer one binary later, thanks very much.
