Hello,

mediaTranscoder.hardwareAccelerationEnabled = [true]|[false]

MediaTranscoder.HardwareAccelerationEnabled

I hope this helps,

Answer 3

Thanks James,

does this API takes care of this Intrernally.When we will put the value as false.

Answer 4

<p>If I understand your question correctly, yes. When you flip this switch to "false" HW acceleration should be "turned off".</p><p>-James</p>

Hi James,

As per your instruction i have kept the values of mediaTranscoder.hardwareAccelerationEnabled = [true]|[false].

But while checking through some tools we are not able to get the Hardware Acceleration. i.e the hardware accleration is not getting enabled.

can you suggest some tools or anything so that we can verify that hardware acceleration is working fine or do we have some problems with the API??

Hello Lazmindhar,

Usually I would recommend that you use GPU View but I have reports that it does not work as expected on Windows 8. You might try using XPerf. I know that we have a lot of performance logging included in Windows 8 but again I'm not entirely sure what is working from the Kernel in the CP. What hardware are you using? What codec are you using? How do you know that HW accelleration is not working?

GPUView.exe
