Hi !

I have installed MSS2017 on ubuntu 16.04LTS. I run sys_analyzer_linux.py to check my configurarion. I configured ffmpeg with x264, x265, libmfx. Compilation is ok. Processor name: Intel(R) Core(TM) i5-6300HQ CPU @ 2.30GHz

I can send the content of my script installation if necessary.

Is somebody could help me ?

 

Thank's a lot

Was a solution ever found for this issue? I seem to be encountering a similar problem, possibly. When I try to run the provided simple_encode (from the mediasdk-tutorials-0.0.3), I receive the following error message:

$ ./simple_encode -g 256x256 -b 5000 -f 30/1

libva info: VA-API version 0.99.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva info: va_openDriver() returns 0

 Device operation failure. src/simple_encode.cpp 167


Or, if I edit mediasdk-tutorials-0.0.3/common/common_vaapi.cpp, line 77:

EDIT
m_fd = open("/dev/dri/card0", 0_RDWR);

CHANGE TO
m_fd = open("/dev/dri/card1", 0_RDWR);

Then I get the following output when running the simple_encode:

$ ./simple_encode -g 256x256 -b 5000 -f 30/1
libva info: VA-API version 0.99.0
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


Which looks like it could be similar to Thierry's problem.


Furthermore, here is the output when I run the provided sys_analyzer_linux.py:

$ ./sys_analyzer_linux.py

Which is a similar output that Thierry is getting from the system analyzer.

Sorry for the delayed reply.

Here are a few things to try:

  • The correct interface to use is /dev/dri/renderD12x.  Here the system analyzer script says the Intel GPU is renderD129.
  • Sometimes there can be complications with other GPUs.  As an experiment, do your results change if you remove the other GPU or disable it in your BIOS?
