## Recording
Here is an example of how to record your monitor and the default audio output: `gpu-screen-recorder -w screen -f 60 -a default_output -o ~/Videos/test_video.mp4`.
Yyou can stop and save the recording with `Ctrl+C` or by running `killall -SIGINT gpu-screen-recorder`.
You can see a list of monitor names to record if you use an invalid monitor name, for example: `gpu-screen-recorder -w invalid -f 60 -o video.mp4`.
You can see a list of capture options to record if you run `gpu-screen-recorder --list-capture-options`. This will list possible capture options and monitor names, for example:\
```
window
DP-1|1920x1080
```
in this case you could record a window or a monitor with the name `DP-1`.
## Streaming
Streaming works the same as recording, but the `-o` argument should be path to the live streaming service you want to use (including your live streaming key). Take a look at `scripts/twitch-stream.sh` to see an example of how to stream to twitch.
## Replay mode

Support application audio recording without pulseaudio combined sink.
If recording application audio setup gsr_pipewire_audio and add gsr_pipewire_audio_add_link_from_app_to_stream for application and the created combined sink.
Use gsr_pipewire_audio_add_link_from_app_to_stream_inverted for inverted scenario. Parse inverted scenario as well.
Support transposing (rotating) with vaapi. This isn't supported on many devices with rgb buffer, but its supported with nv12 buffer (on intel at least).
Link name for stream_name input is wrong. It should be Playback_FL/Playback_FR now with combined sink. Add function for combined sink, or rewrite existing code.
Cleanup pipewire_audio.c (proper error handling and memory cleanup of proxies).
