Recording monitors requires a gpu with NvFBC support (note: this is not required when recording a single window!). Normally only tesla and quadro gpus support this, but by using [nvidia-patch](https://github.com/keylase/nvidia-patch) or [nvlax](https://github.com/illnyang/nvlax) you can do this on all gpus that support nvenc as well (gpus as old as the nvidia 600 series), provided you are not using outdated gpu drivers.

* Dynamically change bitrate/resolution to match desired fps. This would be helpful when streaming for example, where the encode output speed also depends on upload speed to the streaming service.
* Show cursor when recording. Currently the cursor is not visible when recording a window.
-* Implement opengl injection to capture texture. This fixes composition issues and (VRR) without having to use NvFBC direct capture.
+* Implement opengl injection to capture texture. This fixes VRR without having to use NvFBC direct capture.
* Always use direct capture with NvFBC once the capture issue in mpv fullscreen has been resolved (maybe detect if direct capture fails in nvfbc and switch to non-direct recording. NvFBC says if direct capture fails).

Check for reparent.
-Only add window to list if its the window is a topmost window.
-Track window damages and only update then. That is better for output file size.
Quickly changing workspace and back while recording under i3 breaks the screen recorder. i3 probably unmaps windows in other workspaces.
See https://trac.ffmpeg.org/wiki/EncodingForStreamingSites for optimizing streaming.
Add option to merge audio tracks into one (muxing?) by adding multiple audio streams in one -a arg separated by comma.

Use mov+faststart.
Allow recording all monitors/selected monitor without nvfbc by recording the compositor proxy window and only recording the part that matches the monitor(s).
Allow recording a region by recording the compositor proxy window / nvfbc window and copying part of it.
-Resizing the target window to be smaller than the initial size is buggy. The window texture ends up duplicated in the video.
-Handle frames (especially for applications with rounded client-side decorations, such as gnome applications. They are huge).
Use nvenc directly, which allows removing the use of cuda.
Handle xrandr monitor change in nvfbc.
-Add option to track the focused window. In that case the video size should dynamically change (change frame resolution) to match the window size and it should update when the window resizes.
