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: 

1. Run the Intel GPA Monitor.

2. Click the Intel GPA Monitor icon in the taskbar notification area.

3. Select Media Performance….
4. 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
     • DXVA
     • Media SDK
   • Click OK.
5. Launch your media application.
6. 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.
