Linux下录屏

我喜欢的:

1. Gnome系用户，按ctrl+shift+alt+r，屏幕右上角有红点出现，开始录屏，结束的话再按一次ctrl+shift+alt+r，录好的视频在 ~/Videos下
2. ffmpeg

# Use the x11grab device:
ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 output.mp4

# This will grab the image from desktop, starting with the upper-left corner at x=100, y=200 with a width and height of 1024?768.

# If you need audio too, you can use ALSA (see Capture/ALSA for more info):
ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 -f alsa -ac 2 -i hw:0 output.mkv

# Or the pulse input device:
ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+100,200 -f pulse -ac 2 -i default output.mkv
