FFMPEG screen regarding using gdi is working as expected when given offset, width and height on different...
I am working on an application that records the screen using ffmpeg. The recording works fine when I don't specify offset, width and height.
When I specify the offset, width and height on my device and records according to the area but when I run it on a big screen and it records smaller area than provided. I am using following command to record:
ffmpeg -f gdigrab -framerate " + Framerate + " -offset_x " + OffsetX + " -offset_y " + OffsetY + " -video_size " + width + "x" + height + " -show_region 0 -i desktop " + FileName;
I think ffmpeg don't take screen resolution into account or something ?
