Creating a Media Performance Trace Capture File
With the Intel® GPA Monitor you can create media performance trace capture files for analysis with the Intel® GPA Platform Analyzer. Media performance trace capture files provide a system-wide picture of how your code works with Intel® Media SDK and Microsoft* DXVA2 and how media-related workloads execute on the GPU.
To create media performance trace capture files:
Run the Intel GPA Monitor.
Click the Intel GPA Monitor icon in the taskbar notification area.
- Select Media Performance….
- In the Media Performance dialog box > Tracing area:
- Specify the duration of the trace file in milliseconds manually or using the numeric up/down control Duration. Minimum value is 100.
- If you want to automatically open a media performance trace capture file after a successful capture, check the Open trace after capture checkbox.
- Click Configure… to set up capture options. In the Tracing Configuration dialog window select desired event categories to include the following trace information to the trace:
- Display Driver
- Media SDK
- Click OK.
- Launch your media application.
- In the Media Performance dialog box click Capture.
The Intel GPA Monitor saves all media performance trace capture files with the
.gpa_trace extension, along with the 3D graphics trace capture files, in the user’s home directory:
C:Documents and Settings%USERNAME%My DocumentsGPA_2012_R1– the path under Microsoft Windows XP* OS
C:Users%USERNAME%DocumentsGPA_2012_R1– the path under Microsoft Windows Vista* OS and Microsoft Windows* 7 OS
You can open previously saved trace files by running the Intel® GPA Platform Analyzer and selecting File > Open Trace.
