Latest version records an empty green video, and a second after I press the shortcut to stop recording, the program exits. I don't know if this was introduced in this particular version, cause I've missed a couple of updates.

This is on a Thinkpad with Windows 11, Intel GPU HD4600, Core i5 4300M

I tried both the provided binary, and also built it myself.

Hi there, first let me thank you for this amazing tool :)

While the modes capturing the monitor and rectangle work, I've noticed the "active window" mode creates 0-byte files on my system.

If there's anything I can do to help debug this issue, let me know!

Microsoft Windows [Version 10.0.19043.1415]

Cheers

I was trying to run this, and got this error:

My Windows version:

I am definitely meeting the requirement stated. I altered Capture_IsSupported to simply return TRUE and that prevents the error but the program still doesn't appear to run; I've just hidden the error.

I don't know enough about C++ to be able to print out dwMajorVersion and dwBuildNumber to the command line. Apparently, adding #include <stdio.h> at the top of the file isn't enough to make printf work.

Hi, thanks for this terrific work.

I encountered a problem when I use wcap.exe to record games such as HORIZON 5 or Microsoft Flight Simulator, the FPS in result file may drop to 10 or even less especial when the camera moves (the FPS in games didn't fluctuate). I have tried lots of combination settings(including FPS, hardware/software encoding, resolutions, etc...), but none of them helps.

I tried to modify some codes but am unfamiliar with Windows Media Foundation and d3d program. I saw some error logs but I don't know if they were relative to this issue. It happens when the code runs into IMFSinkWriter_SetInputMediaType

BTW, I am using the RX 6900 with the latest Driver, and the System version is windows 11. Do you have any idea about how to improve the recording performance when recording games?

I tried to use the native game recording App by Windows system and obs-studio with WCG used, but neither of them has this problem.

Hi,

Is audio capture via microphone a planned feature? wcap does not appear to record from my attached microphone, but it does capture system audio.

Thanks

… instead of vcvarsall.bat.

Calling “VsDevCmd.bat -arch=x64 -host_arch=x64” does not set the environment variable %Platform% unlike “vcvarsall.bat x64”. %VSCMD_ARG_TGT_ARCH% is defined when invoking both batch files.

Would it be feasible to add the ability to launch (if not already loaded) and trigger active window (or full screen) recording with a flag from the command line (or a script)?

In particular, when recording both window & monitor via Neverwinter Nights Enhanced Edition, I cannot see my cursor while recording. While the recorded video shows it, it does not actually capture what is on my screen.
