中央核心的剧本是这样的：

The central core of the script is something like:

录制屏幕：

ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s $(xwininfo -root | \
  grep 'geometry' | awk '{print $2;}') -i :0.0 -acodec flac -vcodec libx264 \
  -vpre lossless_ultrafast -threads 0 -y output.mkv

录制窗口：

#!/bin/sh INFO=$(xwininfo -frame) WIN_GEO=$(echo $INFO | \
  grep -oEe 'geometry [0-9]+x[0-9]+' | \
  grep -oEe '[0-9]+x[0-9]+')WIN_XY=$(echo $INFO | \
  grep -oEe 'Corners:\s+\+[0-9]+\+[0-9]+' | grep -oEe '[0-9]+\+[0-9]+' | \
  sed -e 's/\+/,/' ) ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 \
  -s $WIN_GEO -i :0.0+$WIN_XY -acodec flac -vcodec libx264 \
  -vpre lossless_ultrafast -threads 0 -y output-single.mkv
