Screen capture

Hi,

Can one use screen capture plugin to capture fullscreen DirectX and OpenGL applications ? I used following command for testing:

sample_decode.exe capture -sw -d3d -fourcc nv12 -async 1 -p 22d62c07e672408fbb4cc20ed7a053e4 -h 1080 -w 1920 -o outputfile.nv12

After invoking this command i switched to DirectX fullscreen window and captured output shows black image.

Thanks,

Alex

Hi Alex, 

Screen capture plugin can capture fullscreen DirectX and OpenGL applications, depending on supported HW, MSDK API version and content (should not be protected) to capture. It bit hard to understand your system setup from your initial comment to triage the issue, hence can you share following details. 

1) Check and confirm if you are using latest MediaSDK 2016:https://software.intel.com/en-us/media-sdk. 

2) Share a log from system analyzer tool : https://software.intel.com/en-us/articles/media-sdk-tools. 

4) You are running latest sample_decode sample version 6.0.0.68: https://software.intel.com/sites/default/files/MediaSamples_Windows_6.0.0.68.msi

3) Please provide more details about directX and OpenGL apps you are running? Are you modifying sample_decode.exe for testing ( or using default from the package). If yes, please share the reproducer. 

Thanks,

Hi Alex, 

Thanks for sharing above details. Currently graphics driver installed on the machine is  old (3517). Update to latest version from here (15.33.4358): https://downloadcenter.intel.com/download/25698/Intel-HD-Graphics-Driver-for-Windows-7-8-1-10-3rd-Gen-BYT-. Re run the test and let me know how it goes.

Currently, system you are using is a 2nd generation system (CPU: Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz) and latest drivers(15.40) supports 6th gen processors ( Code name Skylake), 5th, 4th gen processors. Please note, support on 2nd generation system is very limited and any issues may take longer to fix or may not be fixed. Hence I recommend following suggestions: 1) Upgrade to latest processor or 2) have to work around the issue in your application. 

I tried the same command line ( as above) on a 4th gen and 5th gen processor machine with Direct X application ( Windows media player) and was able to successfully capture the screen and did not see same issue ("captured output shows black image"). Please try on a machine with latest processors and graphics driver installed.

Thanks,
