我用FFMPEG它来录制桌面，正常情况下工作正常，但一旦UAC POPUP出现任何问题，它就会停止工作并退出并出现错误。 Failed to capture image (error 5)有没有解决方案可以解决此错误或任何其他建议。这是我的 ffmpeg 字符串
ffmpeg -framerate 20 -f gdigrab -video_size 800x600 -i desktop -vcodec h264 -pix_fmt yuv420p -preset ultrafast -vsync vfr -b:v 1.5M -bufsize 2M -y d:\output.mp4
这是 UAC 弹出时的错误

您可以在录制期间禁用 UAC。
