Make it possible to select which /dev/dri/card* to use, but that requires opengl to also use the same card. Not sure if that is possible for amd, intel and nvidia without using vulkan instead.
Support I915_FORMAT_MOD_Y_TILED_CCS (and other power saving modifiers, see https://trac.ffmpeg.org/ticket/8542). The only fix may be to use desktop portal for recording. This issue doesn't appear on x11 since these modifiers are not used by xorg server.
Support intel display framebuffer compression (I915_FORMAT_MOD_Y_TILED_CCS modifier) (and other power saving modifiers, see https://trac.ffmpeg.org/ticket/8542). The only fix may be to use desktop portal for recording. This issue doesn't appear on x11 since these modifiers are not used by xorg server.
This issue only appears on some intel iGPUs, such as Intel Iris Xe, see: https://github.com/dec05eba/gpu-screen-recorder-issues/issues/1.
Intel dedicated GPU (intel arc a750) can have a similar issue, but it's not related to compression. In that case the modifier is I915_FORMAT_MOD_4_TILED.
Test if p2 state can be worked around by using pure nvenc api and overwriting cuInit/cuCtxCreate* to not do anything. Cuda might be loaded when using nvenc but it might not be used, with certain record options? (such as h264 p5).
nvenc uses cuda when using b frames and rgb->yuv conversion, so convert the image ourselves instead.-

Try fixing HDR by passing HDR+10 data as well, and in the packet. Run "ffprobe -loglevel quiet -read_intervals "%+#2" -select_streams v:0 -show_entries side_data video.mp4" to test if the file has correct metadata.
Flac is disabled because the frame sizes are too large which causes big audio/video desync.

Add 10-bit capture option. This is good because it reduces banding and quality in very dark areas while reducing the file size compared to doing the same thing with 8-bits.
