## Note
This software works only on X11 (Wayland with Xwayland is NOT supported).\
If you are using a variable refresh rate monitor then choose to record "screen-direct-force". This will allow variable refresh rate to work when recording fullscreen applications. Note that some applications such as mpv will not work in fullscreen mode. A fix is being developed for this.

GPU Screen Recorder only supports h264 and hevc codecs at the moment which means that webm files are not supported.
### TEMPORARY ISSUES
1) screen-direct capture has been temporary disabled as it causes issues with stuttering. This might be a nvfbc bug.
2) Recording the monitor on steam deck might fail sometimes. This happens even when using ffmpeg directly. This might be a steam deck driver bug. Recording a single window doesn't have this issue.

Different streaming sites have limits on bitrate, resolution, etc. For twitch, this is a good place to look: https://help.twitch.tv/s/article/broadcasting-guidelines?language=en_US. For youtube, the information is available here: https://support.google.com/youtube/answer/2853702?hl=en#zippy=%2Cvariable-bitrate-with-custom-stream-keys-in-live-control-room%2Ck-p-fps%2Cp-fps (youtube supports variable bitrate).
Both twitch and youtube support variable bitrate but twitch recommends constant bitrate to reduce stream buffering/dropped frames when going from low motion to high motion: https://help.twitch.tv/s/article/broadcasting-guidelines?language=en_US.
