Hi,

The reason being x11 not working with remote machine is that x11 requires an active X session. x11 is not suitable for headless operation and the only case where one should use X11 option is for local rendering, but this is not well tested or optimized since the focus is on server use cases. So it is best to use drm samples in general scenarios. 

Thanks,
Surbhi

However, I use your demo from http://software.intel.com/sites/default/files/mediasdk-tutorials-0.0.3.tar.gz，I find an error as follow: [root@localhost _build]# ./simple_session libva info: VA-API version 0.35.0 libva info: va_getDriverName() returns -1 libva error: va_getDriverName() failed with unknown libva error,driver_name=(null) terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Aborted (core dumped) It is run in loacal. And the envriment is old envriment. However , this turtorial demo is run sucefully in ubuntu 12.0.4.This hardware envriment is the same as the old envriment of this topic . The system is ubuntu 12.0.4, and the msdk is msdk2014r3.

I want ask if my centos msdk envriment is not establis sucefully.

So far I have seen few cases where this error shows up - 

• If you are not running the tutorial as a root
• if you are running through ssh or vnc which can be fixed by replacing the /dev/dri/card0 with dev/dri/renderD128 in common_vaapi.cpp. Similar discussion being done before - https://software.intel.com/en-us/forums/topic/543365  ;

I believe you are not doing any of the above scenarios. Can you please download the R5 samples package(https://software.intel.com/en-us/intel-media-server-studio-support/code-samples) & verify if you are able to run the samples.  
Also, can you explain what you mean by this - "And the envriment is old envriment."
