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.
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.
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.
Support 10 bit output because of better gradients. May even be smaller file size. Better supported on hevc (not supported at all on h264 on my gpu).
Add nvidia/(amd/intel) specific install script for ubuntu. User should run install_ubuntu.sh but it should run different install dep script depending on if /proc/driver/nvidia/version exists or not. But what about switchable graphics setup?
Test different combinations of switchable graphics. Intel hybrid mode (running intel but possible to run specific applications with prime-run), running pure intel. Detect switchable graphics.
The video output will be black if if the system is suspended on nvidia and NVreg_PreserveVideoMemoryAllocations is not set to 1. This happens because I think that the driver invalidates textures/cuda buffers? To fix this we could try and recreate gsr capture when gsr_capture_capture fails (with timeout to retry again).
Window capture doesn't work properly in _control_ game after going from pause menu to in-game (and back to pause menu). There might be some x11 event we need to catch. Same for vr-video-player.
Fix constant framerate not working properly on amd/intel because capture framerate gets locked to the same framerate as game framerate, which doesn't work well when you need to encode multiple duplicate frames. We can skip multiple encode if we duplicate frame once and then use that same frame data as the difference between frames will be exactly the same, but hevc complains about that. Is there a way to make hevc shut up?
JPEG color range on amd seems to produce too bright video with h264 but not hevc, why?
Window capture performance on steam deck isn't good when playing the witcher 3 for example. The capture itself is fine but video encoding puts it to 30fps even if the game runs at 57 fps.
Monitor capture on steam deck is slightly below the game fps, but only when capturing on the steam deck screen. If capturing on another monitor, there is no issue.
Is this related to the dma buf rotation issue? different modifier being slow? does this always happen?
Fallback to vaapi copy in kms if opengl version fails. This can happen on steam deck for some reason (driver bug?). Also vaapi copy uses less gpu since it uses video codec unit to copy.
Test if vaapi copy version uses less memory than opengl version.
Intel is a bit weird with monitor capture and multiple monitors. If one of the monitors is rotated then all the kms will be rotated as well.
Is that only the case when the primary monitor is rotated? Also the primary monitor becomes position 0, 0 so crtc (x11 randr) position doesn't match the drm pos. Maybe get monitor position and size from drm instead.
