NB: x11grab dont work on windows (its specifically for Linux/X11)Ĭan use wscript.shell to code the line command silently. To capture video only can use ffmpeg -f dshow -i video=UScreenCapture -vf crop=xwidth:xheight:xleft:xtop c:output.flv ffmpeg -f dshow -i video=UScreenCapture:audio=Realtek AC97 Audio -vf crop=xwidth:xheight:xleft:xtop c:output.flv Xleft, xtop the coord of the top left point of the rectangle capture. Xwidth, xheight are the width & height of the region want to capture. Then i used the crop() ffmpeg function to capture any region on the screen.the command line is : There is an error in registry location,in parameters types (dwords are specified by the author but reg_binary is installed)…
I cannot install params of UscreenCapture in registry (tried even on IscrenCapture.h file ).It always provide the full scren capture only. capture screen video and audio (adjust the device audio you have-mine is RealTek AC97 Its sent with an IscrenCapture.h file also. Its registered automatically from the (ScreenCapture.ax file). ScreenCapture can be downloaded for free (google). ffmpeg.exe must be copied in c:windowssystem32 directory for being accessed from anywhere from your PC) *this code is tried successfully on windows XP Sp3 and ffmpeg (last version for windows) This will help for capturing the working screen on windows :įfmpeg -y -rtbufsize 100M -f gdigrab -t 00:00:30 -framerate 30 -probesize 10M -draw_mouse 1 -i desktop -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -crf 25 -pix_fmt yuv420p c:/video_comapre2.mp4 Capture Windows screen with ffmpeg I have encoded to both files and streaming outputs and it works quite well. I found that framerate 10 suits screen capture well (you can change it). To grab the contents of the window named Calculator: ffmpeg -f gdigrab -framerate 25 -i title=Calculator If you want to limit to a region, and show the area being grabbed: ffmpeg -f gdigrab -framerate ntsc -offset_x 10 -offset_y 20 -video_size 640x480 This will capture ALL your displays as one big contiguous display. Use the built-in GDI screengrabber (no install needed) like this : ffmpeg -f gdigrab -framerate 10 -i desktop
