How do I record a meeting on my computer from Windows 10?

More and more people are interested in how to use my computer to record a meeting. For potentially better performance, especially on Windows 10 or newer, FF mpeg offers more advanced screen capture methods .

Using the gfxcapture Filter: This is a newer filter that uses the Windows.Graphics.Capture API. It can capture specific windows, even if they are partially hidden .

bash
ff mpeg -filter_complex gfxcapture=window_title='(?i)Meeting App':max_framerate=60,hwdownload,format=bgra,format=yuv420p -c:v libx264 -crf 15 capture.mp4

Using the Desktop Duplication API (ddagrab): This method grabs frames directly from the GPU, which is highly efficient and can reduce CPU load . It works well with hardware encoders.

bash
ff mpeg -init_hw_device d3d11va -filter_complex ddagrab=0 -c:v h264_nvenc -cq:v 20 output.mp4

A common need when how to use my computer to record a meeting is to capture the audio coming from the meeting application. FF mpeg on Windows does not have a native way to record system audio.

To do this, you need to install a virtual audio cable driver. Once installed, it appears as a new audio device that you can select as your audio input in FF mpeg, effectively "recording" what you hear. To stop the recording at any time, simply go back to the command prompt and press Ctrl + C .
