Media SDK fails when using in a Windows service

 

Hello Forum,

when using the Media SDK in a Windows service the function MFXVideoENCODE_Query always fails with return code WRN_PARTIAL_ACCELERATION. When we run the same code as usual program, then it returns OK (ERR_NONE). This results in very high CPU load when encoding H264 video in the service. Can anyone help or give advise, please?

The output of the "mediasdk_system_analyzer_64.exe" is:

SNIP ---------->

Intel(R) Media Server Studio 2016 R2 - System Analyzer (64-bit)

<----------- SNAP

The output is strange, because according to it Media SDK with version > 1.11 is not supported for hardware encoding/decoding, but as mentioned above: when running as usual program the encoding works fine with very low CPU load.

Thanks for your help.

Michael
