avt will try to source ~/.avtrc if it exists. You have access to the findmonitor function in there.
|
||||
|
||||
# Dependencies
|
||||
|
||||
- `bash`
|
||||
- `ffmpeg`
|
||||
- `perl`
|
||||
- `pactl`
|
||||
|
||||
# Requirements
|
||||
|
||||
This assumes you use X11, PipeWire and pipewire-pulse.
|
||||
You also need a pretty fast disk and a lot of free space to record with this tool with the default settings. Consider increasing [`rec_crf`](https://trac.ffmpeg.org/wiki/Encode/H.264#crf) or choosing a slower [`rec_preset`](https://trac.ffmpeg.org/wiki/Encode/H.264#Preset) if you don't have those.
