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.
Look at VK_EXT_external_memory_dma_buf.
Allow setting a different output resolution than the input resolution.
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).

Disable flipping on nvidia? this might fix some stuttering issues on some setups. See NvCtrlGetAttribute/NvCtrlSetAttributeAndGetStatus NV_CTRL_SYNC_TO_VBLANK https://github.com/NVIDIA/nvidia-settings/blob/d5f022976368cbceb2f20b838ddb0bf992f0cfb9/src/gtk%2B-2.x/ctkopengl.c.
Replays seem to have some issues with audio/video. Why?
Cleanup unused gl/egl functions, macro, etc.
Add option to disable overlapping of replays (the old behavior kinda. Remove the whole replay buffer data after saving when doing this).
Set audio track name to audio device name (if not merge of multiple audio devices).
Add support for webcam, but only really for amd/intel because amd/intel can get drm fd access to webcam, nvidia cant. This allows us to create an opengl texture directly from the webcam fd for optimal performance.
Reverse engineer nvapi so we can disable "force p2 state" on linux too (nvapi profile api with the settings id 0x50166c5e).

Disable gpu screen recorder black bar handling when using hevc on amd when the libavcodec version is the one that comes after those commits.
Also consider the mesa version, to see if the gpu supports this.
Use opengl compute shader instead of graphics shader. This might allow for better performance when games are using 100% of graphics unit which might fix issue with 100% gpu usage causing gpu screen recorder to run slow when not using vaapi to convert rgb to nv12(?).
