 ### TEMPORARY ISSUES
-1) screen-direct capture has been temporary disabled as it causes issues with stuttering. This might be a nvfbc bug.
-2) Videos are in variable framerate format. Use MPV to play such videos, otherwise you might experience stuttering in the video if you are using a buggy video player. You can try saving the video into a .mkv file instead as some software may have better support for .mkv files (such as kdenlive). You can use the "-fm cfr" option to to use constant framerate mode.

 # Performance
 On a system with a i5 4690k CPU and a GTX 1080 GPU:\
 When recording Legend of Zelda Breath of the Wild at 4k, fps drops from 30 to 7 when using OBS Studio + nvenc, however when using this screen recorder the fps remains at 30.\
 When recording GTA V at 4k on highest settings, fps drops from 60 to 23 when using obs-nvfbc + nvenc, however when using this screen recorder the fps only drops to 58.\
-GPU Screen Recorder also produces much smoother videos than OBS when GPU utilization is close to 100%, see comparison here: [https://www.youtube.com/watch?v=zfj4sNVLLLg](https://www.youtube.com/watch?v=zfj4sNVLLLg).\

 GPU Screen Recorder has much better performance than OBS Studio even with version 30.2 that does "zero-copy" recording and encoding, see: [https://www.youtube.com/watch?v=jdroRjibsDw](https://www.youtube.com/watch?v=jdroRjibsDw).\
-It is recommended to save the video to a SSD because of the large file size, which a slow HDD might not be fast enough to handle. Using variable framerate mode (-fm vfr) which is the default is also recommended as this reduces encoding load. Ultra quality is also overkill most of the time, very high (the default) or lower quality is usually enough.

Ultra quality is also overkill most of the time, very high (the default) or lower quality is usually enough.\
+Note that for best performance you should close other screen recorders such as OBS Studio when using GPU Screen Recorder even if they are not recording, since they can affect performance even when idle. This is the case with OBS Studio.
 ## Note about optimal performance on NVIDIA
 NVIDIA driver has a "feature" (read: bug) where it will downclock memory transfer rate when a program uses cuda (or nvenc, which uses cuda), such as GPU Screen Recorder. To work around this bug, GPU Screen Recorder can overclock your GPU memory transfer rate to it's normal optimal level.\
 To enable overclocking for optimal performance use the `-oc` option when running GPU Screen Recorder. You also need to have "Coolbits" NVIDIA X setting set to "12" to enable overclocking. You can automatically add this option if you run `sudo nvidia-xconfig --cool-bits=12` and then reboot your computer.\
 Note that this only works when Xorg server is running as root, and using this option will only give you a performance boost if the game you are recording is bottlenecked by your GPU.\
 Note! use at your own risk!
 # VRR/G-SYNC

 ## Recording
 Here is an example of how to record your monitor and the default audio output: `gpu-screen-recorder -w screen -f 60 -a default_output -o ~/Videos/test_video.mp4`.
-Yyou can stop and save the recording with `Ctrl+C` or by running `killall -SIGINT gpu-screen-recorder`.
-You can see a list of monitor names to record if you use an invalid monitor name, for example: `gpu-screen-recorder -w invalid -f 60 -o video.mp4`.
+Yyou can stop and save the recording with `Ctrl+C` or by running `pkill -SIGINT -f gpu-screen-recorder`.
+You can see a list of capture options to record if you run `gpu-screen-recorder --list-capture-options`. This will list possible capture options and monitor names, for example:\
+```
+  window
+  DP-1|1920x1080
+```
+in this case you could record a window or a monitor with the name `DP-1`.\
+To list available audio devices that you can use you can run `gpu-screen-recorder --list-audio-devices` and the name to use is on the left size of the `|`.\
+To list available audio application names that you can use you can run `gpu-screen-recorder --list-application-audio`.
 ## Streaming
-Streaming works the same as recording, but the `-o` argument should be path to the live streaming service you want to use (including your live streaming key). Take a look at `scripts/twitch-stream.sh` to see an example of how to stream to twitch.
+Streaming works the same way as recording, but the `-o` argument should be path to the live streaming service you want to use (including your live streaming key). Take a look at `scripts/twitch-stream.sh` to see an example of how to stream to twitch.\
+GPU Screen Recorder uses Ffmpeg so GPU Screen Recorder supports all protocols that Ffmpeg supports.\
+If you want to reduce latency one thing you can do is to use the `-keyint` option, for example `-keyint 0.5`. Lower value means lower latency at the cost of increased bitrate/decreased quality.
 ## Replay mode
 Run `gpu-screen-recorder` with the `-c mp4` and `-r` option, for example: `gpu-screen-recorder -w screen -f 60 -r 30 -c mp4 -o ~/Videos`. Note that in this case, `-o` should point to a directory.\
 If `-df yes` is set, replays are save in folders based on the date.
 The file path to the saved replay is output to stdout. All other output from GPU Screen Recorder are output to stderr.
 You can also use the `-sc` option to specify a script that should be run (asynchronously) when the video has been saved and the script will have access to the location of the saved file as its first argument.
-This can be used for example to show a notification when a replay has been saved, to rename the video with a title that matches the game played (see `scripts/record-save-application-name.sh` as an example on how to do this on X11) or to re-encode the video.\
-The replay buffer is stored in ram (as encoded video), so don't use a too large replay time and/or video quality unless you have enough ram to store it.
-## Controlling GPU Screen Recorder remotely
-To save a video in replay mode, you need to send signal SIGUSR1 to gpu screen recorder. You can do this by running `killall -SIGUSR1 gpu-screen-recorder`.\
-To stop recording send SIGINT to gpu screen recorder. You can do this by running `killall -SIGINT gpu-screen-recorder` or pressing `Ctrl-C` in the terminal that runs gpu screen recorder. When recording a regular non-replay video this will also save the video.\
-To pause/unpause recording send SIGUSR2 to gpu screen recorder. You can do this by running `killall -SIGUSR2 gpu-screen-recorder`. This is only applicable and useful when recording (not streaming nor replay).\
-## Finding audio device name
-You can find the default output audio device (headset, speakers (in other words, desktop audio)) with the command `pactl get-default-sink`. Add `monitor` to the end of that to use that as an audio input in gpu screen recorder.\
-You can find the default input audio device (microphone) with the command `pactl get-default-source`. This input should not have `monitor` added to the end when used in gpu screen recorder.\
-Example of recording both desktop audio and microphone: `gpu-screen-recorder -w screen -f 60 -a "$(pactl get-default-sink).monitor" -a "$(pactl get-default-source)" -o ~/Videos/test_video.mp4`.\
-A name (that is visible to pipewire) can be given to an audio input device by prefixing the audio input with `<name>/`, for example `dummy/$(pactl get-default-sink).monitor`.\
-Note that if you use multiple audio inputs then they are each recorded into separate audio tracks in the video file. If you want to merge multiple audio inputs into one audio track then separate the audio inputs by "|" in one -a argument,
-for example `-a "$(pactl get-default-sink).monitor|$(pactl get-default-source)"`.
+This can be used for example to show a notification when a replay has been saved, to rename the video with a title that matches the game played (see `scripts/record-save-application-name.sh` as an example on how to do this on X11) or to re-encode the video.
 
-There is also a gui for the gpu screen recorder called [gpu-screen-recorder-gtk](https://git.dec05eba.com/gpu-screen-recorder-gtk/).
+The replay buffer is stored in ram (as encoded video) by default, so don't use a too large replay time and/or video quality unless you have enough ram to store it.\
+You can use the `-replay-storage disk` option to store the replay buffer on disk instead of ram (in the same location as the output video).\
+By default videos are recorded with constant quality, but with replay mode you might want to record in constant bitrate mode instead for consistent ram/disk usage in high motion scenes. You can do that by using the `-bm cbr` option (along with `-q` option, for example `-bm cbr -q 20000`).
+## Recording while using replay/streaming
+You can record a regular video while using replay/streaming by launching GPU Screen Recorder with the `-ro` option to specify a directory where to save the recording.\
+To start/stop (and save) recording use the SIGRTMIN signal, for example `pkill -SIGRTMIN -f gpu-screen-recorder`. The name of the video will be displayed in stdout when saving the video.\
+This way of recording while using replay/streaming is more efficient than running GPU Screen Recorder multiple times since this way it only records the screen and encodes the video once.
+## Controlling GPU Screen Recorder remotely
+To save a video in replay mode, you need to send signal SIGUSR1 to gpu screen recorder. You can do this by running `pkill -SIGUSR1 -f gpu-screen-recorder`.\

 ## Simple way to run replay without gui

+This can be used to for example showing a notification with the name of video or moving a video to a folder based on the name of the game that was recorded.
+## Plugins
+GPU Screen Recorder supports plugins for rendering additional graphics on top of the monitor/window capture. The plugin interface is defined in `plugin/plugin.h` and it gets installed to `gsr/plugin.h` in the systems include directory (usually `/usr/include`).
+An example plugin can be found at `plugin/examples/hello_triangle`.\

 # Issues
 ## NVIDIA
 Nvidia drivers have an issue where CUDA breaks if CUDA is running when suspend/hibernation happens, and it remains broken until you reload the nvidia driver. `extra/gsr-nvidia.conf` will be installed by default when you install GPU Screen Recorder and that should fix this issue. If this doesn't fix the issue for you then your distro may use a different path for modprobe files. In that case you have to install that `extra/gsr-nvidia.conf` yourself into that location.

 ## It tells me that my AMD/Intel GPU is not supported or that my GPU doesn't support h264/hevc, but that's not true!
 Some linux distros (such as manjaro and fedora) disable hardware accelerated h264/hevc on AMD/Intel because of "patent license issues". If you are using an arch-based distro then you can install mesa-git instead of mesa and if you are using another distro then you may have to switch to a better distro. On fedora based distros you can follow this: [Hardware Accelerated Codec](https://rpmfusion.org/Howto/Multimedia).\

 Reverse engineer nvapi so we can disable "force p2 state" on linux too (nvapi profile api with the settings id 0x50166c5e).

 Use SRC_W and SRC_H for screen plane instead of crtc_w and crtc_h.
 
-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.
-
 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.-
 
-Mesa doesn't support global headers (AV_CODEC_FLAG_GLOBAL_HEADER) with h264... which also breaks mkv since mkv requires global header. Right now gpu screen recorder will forcefully set video codec to hevc when h264 is requested for mkv files.
-
 Drop frames if live streaming cant keep up with target fps, or dynamically change resolution/quality.
 
-Support low power option.
-
 Instead of sending a big list of drm data back to kms client, send the monitor we want to record to kms server and the server should respond with only the matching monitor, and cursor.
 
 Tonemap hdr to sdr when hdr is enabled and when hevc_hdr/av1_hdr is not used.
 
-Add 10 bit record option, h264_10bit, hevc_10bit and av1_10bit.
-
 Rotate cursor texture properly (around top left origin).
 
-Setup hardware video context so we can query constraints and capabilities for better default and better error messages.
-
-Use CAP_SYS_NICE in flatpak too on the main gpu screen recorder binary. It makes recording smoother, especially with constant framerate.
-
 Modify ffmpeg to accept opengl texture for nvenc encoding. Removes extra buffers and copies.
 
 When vulkan encode is added, mention minimum nvidia driver required. (550.54.14?).
 
-Support drm plane rotation. Neither X11 nor any Wayland compositor currently rotates drm planes so this might not be needed.
-
 Investigate if there is a way to do gpu->gpu copy directly without touching system ram to enable video encoding on a different gpu. On nvidia this is possible with cudaMemcpyPeer, but how about from an intel/amd gpu to an nvidia gpu or the other way around or any combination of iGPU and dedicated GPU?
     Maybe something with clEnqueueMigrateMemObjects? on AMD something with DirectGMA maybe?
 
 Go back to using pure vaapi without opengl for video encoding? rotation (transpose) can be done if its done after (rgb to yuv) color conversion.
 
-Implement scaling and use lanczos resampling for better quality. Lanczos resampling can also be used for YUV chroma for better color quality on small text.
+Use lanczos resampling for better scaling quality. Lanczos resampling can also be used for YUV chroma for better color quality on small text.
 
 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.
-
 Enable b-frames.
 
 Support vfr matching games exact fps all the time. On x11 use damage tracking, on wayland? maybe there is drm plane damage tracking. But that may not be accurate as the compositor may update it every monitor hz anyways. On wayland maybe only support it for desktop portal + pipewire capture.
     Another method to track damage that works regardless of the display server would be to do a diff between frames with a shader.
+    A 1x1 texture could be created and then write to the texture with imageStore in glsl.
+    Multiple textures aren't needed for diff, the diff between the color conversion output can be done by using it as an input
+    as well, which would diff it against the previous frame.
 
 Support selecting which gpu to use. This can be done in egl with eglQueryDevicesEXT and then eglGetPlatformDisplayEXT. This will automatically work on AMD and Intel as vaapi uses the same device. On nvidia we need to use eglQueryDeviceAttribEXT with EGL_CUDA_DEVICE_NV.
     Maybe on glx (nvidia x11 nvfbc) we need to use __NV_PRIME_RENDER_OFFLOAD, __NV_PRIME_RENDER_OFFLOAD_PROVIDER, __GLX_VENDOR_LIBRARY_NAME, __VK_LAYER_NV_optimus, VK_ICD_FILENAMES instead. Just look at prime-run /usr/bin/prime-run.

+    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.
+    The version is libavcodec >= 61.28.100
+
+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(?).
+
+Always disable prime run/dri prime and list all monitors to record from from all cards.
+    Do this instead of adding an option to choose which gpu to use.
+    On X11 the primary gpu will always have the framebuffer for all monitors combined.
+        Use randr to list all monitors and always record and encode with the primary gpu.
+    On Wayland each gpu will have its own list of monitors with framebuffers.
+        Iterate through all cards with drm and list all monitors with associated framebuffers and when choosing a monitor to record
+        automatically use the associated gpu card.

+
+Replay (and recording?) fails to save properly sometimes (especially for long videos). This is noticable with mp4 files since they get corrupt and become unplayable.
+    The entire video does seem to get saved (it's a large video file) and it seems to have the correct headers but it's not playable.
+
+Make it possible to save a shorter replay clip remotely. Maybe implement ipc first, to then also allow starting recording/stream while a replay is running.
+
+Add an option to pass http headers when streaming. Some streaming services require streaming keys to be passed in a http header instead of in the url as a parameter.
+
+When adding vulkan video support add VK_VIDEO_ENCODE_TUNING_MODE_LOW_LATENCY_KHR.
+
+Implement screenshot without invoking opengl (which is slow to start on some systems).
+
+Automatically use desktop portal on wayland when hdr is enabled (or night light) by checking if kms hdr metadata exists, if hdr video codec is not used.
+    Or maybe do this in the ui?
+
+Detect if cached portal session token is no longer valid (this can happen if the user switches to another wayland compositor).
+
+Support reconnecting (and setting things up again) if the audio server is restarted (for both device recording and app recording).
+
+Find out how nvidia-smi fixes nvenc not working on opensuse and do that ourselves instead of relying on nvidia-smi that is not always installed.
+
+Pulseaudio code: add "running" variable to loops to allow stopping the running code when quitting.
+
+Scale screenshot frame libswscale or implement lanczos shader for improved scaline for video as well.
+
+Support high quality scaling with -s by using lanczos.
+
+Support spanning multiple monitors with region capture. This would also allow the user to record multiple monitors at the same time, the same way screen-direct works on nvidia x11.
+
+When webcam support is added also support v4l2loopback? this is done by using avdevice_register_all(); and -c v4l2 -o /dev/video0; but it needs to output raw data as well instead of h264 and possibly yuv420p. Maybe add a -k yuv420p option to do that or -k rgb.
+    This would be implemented by outputting the raw data directly into the output file, without using the video encoder.
+
+Do proper exit, to call gsr_capture_destroy which will properly stop gsr-kms-server. Otherwise there can be zombie gsr-kms-server on error.
+
+Replace all scissors with clearing textures if the cursor hits the outside of the frame image.
+
+Cursor position might be slightly wrong on rotated monitor.
+
+External texture doesn't work on nvidia x11, probably because of glx context (requires gles es). External texture is not used on nvidia x11 right now so it's not an issue.
+
+Add option to save replay buffer on disk instead of ram.
+
+nvfbc capture cursor with cursor.h instead and composite that on top. This allows us to also always get a cursor in direct capture mode. This could possible give better performance as well.
+
+Maybe remove external shader code and make a simple external to internal texture converter (compute shader), to reduce texture sampling. Maybe this is faster?
+
+Fix opengl context broken after suspend on nvidia by using this: https://registry.khronos.org/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt requires glx context creation flags and GetGraphicsResetStatusARB() == PURGED_CONTEXT_RESET_NV check to recreate all graphics.
+
+HDR looks incorrect, brightest point gets cut off.
+
+Make "screen" capture the preferred monitor.
+
+When webcam support is added add the option to add it as a second video track, to make it easier to edit in video editors.
+
+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 (AMD/Intel is slow at encoding!).
+    It also appears to skip audio frames on nvidia wayland? why? that should be fine, but it causes video stuttering because of audio/video sync.
+
+Add option to pass a fd (from socketpair) to use for rpc. In the rpc have a common header, with protocol version, data type and data in an enum.
+
+Add the option to set audio track name, for example with -a "track-name:blabla|device:default_output|app:firefox"
+
+Maybe disable qp/vbr for replay. In that case we can preallocate all replay data (for both ram and disk) and write to that directly when receiving packet (dont do that when also recording at the same time).
+    That could improve performance/disk write optimization and maybe even reduce ram usage because of less blocks/fragmentation.
+
+When rpc is added add the option to add/remove audio devices/app audio and also overlays (from new capture sources).
+
+Support hdr screenshot.
+
+Recreate opengl context on loss. This can happen if there is a gpu driver bug, causing context to need to be recreated. This is a nice improvement to not break recording even with buggy driver.
+
+Support saving video with surround sound. Surround sound audio capture does work, but it gets downmixed to stereo.
+
+Add (render) plugin support. To simplify it (and possibly best performance) create one rgba texture (with the size of the output video) that is used across all plugins.
+    Create a framebuffer and set this texture and the target and set the framebuffer as active before calling the plugins.
+    Then the plugins can render simply by doing simple opengl draw functions.
+    Maybe send some metadata to the plugin, such as video (and framebuffer) size. Although this data can be retrieved from the active framebuffer.
+
+Either support webcam support with raw yuyv, mapping the buffer directly to opengl. Or use mjpeg, mapping the buffer directly to vaapi jpeg decoder and then get then map the decoded buffer to opengl.
+    Some webcams dont support raw yuyv and many webcams support higher framerates for mjpeg.
+
+Allow medium, high, very_high and ultra quality for -bm cbr. If that is used then it will automatically estimate the best bitrate for that quality based on resolution and fps.
+    Maybe do this in the ui instead (or both?), to show estimated file size.
+
+Maybe remove shader compute code. It doesn't seem necessary anymore now that glSwapBuffer/glFinish isn't used. dbus server isn't needed anymore either, the code can be moved back to the gpu screen recorder process.
+
+Add proper check if opengl functions are supported. dlsym for the symbol will return a no-op function if it's not supported, so it silently fails if used.
+
+Colors are offset to bottom left by 1 pixel or so on steam deck in landscape mode.
+
+When constant framerate is used (and for audio) multiple frames need to be encoded after resuming from suspend.
+    The clock jumps forward by around 2-3 seconds (on my machine). Is there a way to make sure the clock doesn't jump forward?
+
+Colors are correct, but they look incorrect for thin elements, such as colored text. This can be improved by sampling neighbor pixels for color average.
+
+Record first video/audio frame immediately.
+
+Disable GL_DEPTH_TEST, GL_CULL_FACE.
+
+kde plasma portal capture for screenshot doesn't work well because the portal ui is still visible when taking a screenshot because of its animation.
+
+It's possible for microphone audio to get desynced when recording together with desktop audio, when not recording app audio as well.
+    Test recording desktop audio and microphone audio together (-a "default_output|default_input") for around 30 minutes.
+
+We can use dri2connect/dri3open to get the /dev/dri/card device. Note that this doesn't work on nvidia x11.
+
+Add support for QVBR (QP with target bitrate).
+
+KDE Plasma Wayland seems to use overlay planes now in non-fullscreen mode(limited to 1 overlay plane per gpu). Check if this is the case in the latest kde on arch linux.
+    If it is, then support it in kms capture.
+
+Check if pipewire audio link-factory is available before attempting to use app audio or merging audio with pipewire.
+    Also do the same in supports_app_audio check in gpu-screen-recorder --info output.

+  <description summary="Protocol to describe output regions">
+    This protocol aims at describing outputs in a way which is more in line
+    with the concept of an output on desktop oriented systems.
+
+    Some information are more specific to the concept of an output for
+    a desktop oriented system and may not make sense in other applications,
+    such as IVI systems for example.
+
+    Typically, the global compositor space on a desktop system is made of
+    a contiguous or overlapping set of rectangular regions.
+
+    The logical_position and logical_size events defined in this protocol
+    might provide information identical to their counterparts already
+    available from wl_output, in which case the information provided by this
+    protocol should be preferred to their equivalent in wl_output. The goal is
+    to move the desktop specific concepts (such as output location within the
+    global compositor space, etc.) out of the core wl_output protocol.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible
+    changes may be added together with the corresponding interface
+    version bump.
+    Backward incompatible changes are done by bumping the version
+    number in the protocol and interface names and resetting the
+    interface version. Once the protocol is to be declared stable,
+    the 'z' prefix and the version number in the protocol and
+    interface names are removed and the interface version number is
+    reset.

+
+	Most regular Wayland clients should not pay attention to the
+	logical size and would rather rely on xdg_shell interfaces.
+
+	Some clients such as Xwayland, however, need this to configure
+	their surfaces in the global compositor space as the compositor
+	may apply a different scale from what is advertised by the output
+	scaling property (to achieve fractional scaling, for example).
+
+	For example, for a wl_output mode 3840×2160 and a scale factor 2:
+
+	- A compositor not scaling the monitor viewport in its compositing space
+	  will advertise a logical size of 3840×2160,
+
+	- A compositor scaling the monitor viewport with scale factor 2 will
+	  advertise a logical size of 1920×1080,
+
+	- A compositor scaling the monitor viewport using a fractional scale of
+	  1.5 will advertise a logical size of 2560×1440.
+
+	For example, for a wl_output mode 1920×1080 and a 90 degree rotation,
+	the compositor will advertise a logical size of 1080x1920.
+
+	The logical_size event is sent after creating an xdg_output
+	(see xdg_output_manager.get_xdg_output) and whenever the logical
+	size of the output changes, either as a result of a change in the
+	applied scale or because of a change in the corresponding output
+	mode(see wl_output.mode) or transform (see wl_output.transform).
