remove the following lines from install\_software.sh:
```bash
ffmpeg -vsync 0 -hwaccel cuda -hwaccel_output_format cuda `# we need nvidia acceleration because of low fps without it` \
--r 30 -video_size 640x480 -i /dev/video0 `# this is camera` \
--f alsa -i default -async 1 `# this is audio. Why not pulse? Nvidia?` \
--c:v h264_nvenc `# this is video codec` \
video.mp4 # output file
```
Also, remove the filter\_complex line and the x11grab section.
This refactoring is done to simplify the script and make it more focused on installing software rather than recording the screen.
