Hi,

Can you please send the system analyzer log from your machine?

Execute the binary “<install-folder>\tools\mediasdk_sys_analyzer\win32\sys_analyzer.exe” or
“<install-folder>\tools\mediasdk_sys_analyzer\x64\sys_analyzer.exe” in your machine. Send a copy of it.

Thanks!

Hi Zhou,

Thanks for sharing the log.

Screen Capture (MFX_CODEC_CAPTURE) is supported from API 1.15, which is not supported with your current graphics driver. Please update the driver at https://downloadcenter.intel.com/ to the latest version (15.36.31.4414). It should fix your issue.

Try it and let us know.

thanks for answer.

When I install the latest driver( win64_153631.4414),

indicate that the system can't install.(error info :this operating system is not supported).

1 about driver

Because the system is a custom OS, driver from Inter could not be updated.

When I driver from lenovo's official website,it also can not install.

I ready to confirm on other computer.

2 about h264 file can't play

I changed player tool from VLC player to storm player, the h264 file can be play well.

NikhilKuma_R_Intel · ‎07-18-2016

When you observed the error (error info :this operating system is not supported), did you make sure your download was for Windows 7 64-bit OS? If not, try this link https://downloadcenter.intel.com/product/75459/Intel-Core-i5-4200U-Processor-3M-Cache-up-to-2-60-GHz-

If you can provide me with the Lenovo model & serial number, I may be able to make sure that you have a right driver installed.

Anyway, it's good to hear that you are ready to test on other system. Please let me know the result.

Yes, VLC may not be playing the elementary streams. I personally use 'mplayer' to play such streams. You may use any application of your choice.

Thank you for the regular updates.
