The quality is also much better when using gpu screen recorder.\ -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.\ -Note that if you have a very powerful CPU and a not so powerful GPU and play a game that is bottlenecked by your GPU and barely uses your CPU then a CPU based screen recording (such as OBS with libx264 instead of nvenc) might perform slightly better than GPU Screen Recorder. At least on NVIDIA. +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) and [https://www.youtube.com/watch?v=aK67RSZw2ZQ](https://www.youtube.com/watch?v=aK67RSZw2ZQ).\ +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.\ +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! -## Note about optimal performance on AMD/Intel -Performance is the same when recording a single window or the monitor, however in some cases, such as when gpu usage is 100%, the video capture rate might be slower than the games fps when recording a single window instead of a monitor. Recording the monitor instead is recommended in such cases. +# VRR/G-SYNC +This should work fine on AMD/Intel X11 or Wayland. On Nvidia X11 G-SYNC only works with the -w screen-direct option, but because of bugs in the Nvidia driver this option is not always recommended. +For example it can cause your computer to freeze when recording certain games. # Installation -If you are running an Arch Linux based distro, then you can find gpu screen recorder on aur under the name gpu-screen-recorder-git (`yay -S gpu-screen-recorder-git`).\ +If you are running an Arch Linux based distro then you can find gpu screen recorder on aur under the name gpu-screen-recorder (`yay -S gpu-screen-recorder`).\ If you are running another distro then you can run `sudo ./install.sh`, but you need to manually install the dependencies, as described below.\ You can also install gpu screen recorder ([the gtk gui version](https://git.dec05eba.com/gpu-screen-recorder-gtk/)) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder), which is the easiest method to install GPU Screen Recorder on non-arch based distros.\ -The only official ways to install GPU Screen Recorder is either from source, AUR or flathub.

Note that in this case, `-o` should point to a directory.\ -If `-mf yes` is set, replays are save in folders based on the date. -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.

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. +## 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`.\ +To stop recording send SIGINT to gpu screen recorder. You can do this by running `pkill -SIGINT -f 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 `pkill -SIGUSR2 -f gpu-screen-recorder`. This is only applicable and useful when recording (not streaming nor replay).\ +There are more signals to control GPU Screen Recorder. Run `gpu-screen-recorder --help` to list them all (under `NOTES` section). ## Simple way to run replay without gui Run the script `scripts/start-replay.sh` to start replay and then `scripts/save-replay.sh` to save a replay and `scripts/stop-replay.sh` to stop the replay. The videos are saved to `$HOME/Videos`. You can use these scripts to start replay at system startup if you add `scripts/start-replay.sh` to startup (this can be done differently depending on your desktop environment / window manager) and then go into hotkey settings on your system and choose a hotkey to run the script `scripts/save-replay.sh`. Modify `scripts/start-replay.sh` if you want to use other replay options. ## Run replay on system startup -If you are running a distro that uses systemd then the `install.sh` script installs `extra/gpu-screen-recorder.service` on the system and that systemd service can be started with `systemctl enable --now --user gpu-screen-recorder` -and it's configured with `$HOME/.config/gpu-screen-recorder.env` (create it if it doesn't exist). -You can see which variables that you can use in the `gpu-screen-recorder.env` file by looking at the `extra/gpu-screen-recorder.service` file. In general you only need to set the `WINDOW` variable to a monitor to make it work. -You can use the `scripts/save-replay.sh` script to save a replay and by default the systemd service saves files in `$HOME/Videos`.\ -If you are using a NVIDIA GPU then it's recommended to set PreserveVideoMemoryAllocations=1 as mentioned in the section below. -## Issues -### NVIDIA -Nvidia drivers have an issue where CUDA breaks if CUDA is running when suspend/hibernation happens, and it remains broken until you reload the nvidia driver. To fix this, either disable suspend or tell the NVIDIA driver to preserve video memory on suspend/hibernate by using the `NVreg_PreserveVideoMemoryAllocations=1` option. You can run `sudo extra/install_preserve_video_memory.sh` to automatically add that option to your system. +If you installed GPU Screen Recorder from AUR or from source and you are running a distro that uses systemd then you will have a systemd service installed that can be started with `systemctl enable --now --user gpu-screen-recorder`. This systemd service runs GPU Screen Recorder on system startup.\ +It's configured with `$HOME/.config/gpu-screen-recorder.env` (create it if it doesn't exist). You can look at [extra/gpu-screen-recorder.env](https://git.dec05eba.com/gpu-screen-recorder/plain/extra/gpu-screen-recorder.env) to see an example. +You can see which variables that you can use in the `gpu-screen-recorder.env` file by looking at the `extra/gpu-screen-recorder.service` file. Note that all of the variables are optional, you only have to set the ones that are you interested in. +You can use the `scripts/save-replay.sh` script to save a replay and by default the systemd service saves videos in `$HOME/Videos`. +# 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. +You have to reboot your computer after installing GPU Screen Recorder for the first time for the fix to have any effect. +# Examples +Look at the [scripts](https://git.dec05eba.com/gpu-screen-recorder/tree/scripts) directory for script examples. For example if you want to automatically save a recording/replay into a folder with the same name as the game you are recording. -# Reporting bugs/contributing patches -See [https://git.dec05eba.com/?p=about](https://git.dec05eba.com/?p=about) +# Reporting bugs, contributing patches, questions or donation +See [https://git.dec05eba.com/?p=about](https://git.dec05eba.com/?p=about). # Demo [](https://www.youtube.com/watch?v=n5tm0g01n6A) # FAQ -## How is this different from using OBS with nvenc? -OBS only uses the gpu for video encoding, but the window image that is encoded is copied from the GPU to the CPU and then back to the GPU (video encoding unit). These operations are very slow and causes all of the fps drops when using OBS. OBS only uses the GPU efficiently on Windows 10 and Nvidia.\ -This gpu screen recorder keeps the window image on the GPU and sends it directly to the video encoding unit on the GPU by using CUDA. This means that CPU usage remains at around 0% when using this screen recorder. -## How is this different from using OBS NvFBC plugin? -The plugin does everything on the GPU and gives the texture to OBS, but OBS does not know how to use the texture directly on the GPU so it copies the texture to the CPU and then back to the GPU (video encoding unit). These operations are very slow and causes a lot of fps drops unless you have a fast CPU. This is especially noticable when recording at higher resolutions than 1080p. -## How is this different from using FFMPEG with x11grab and nvenc? -FFMPEG only uses the GPU with CUDA when doing transcoding from an input video to an output video, and not when recording the screen when using x11grab.

The NvEncodeAPI interface will need to + keep a copy of the input buffers for re-ordering and it allocates following + internal buffers (NvI1, NvI2...). These internal buffers are managed by NvEncodeAPI + and the client is not responsible for the allocating or freeing the memory of + the internal buffers. + + a) The client main thread will queue the following encode frame calls. + Note the picture type is unknown to the client, the decision is being taken by + NvEncodeAPI interface. The client should pass ::_NV_ENC_PIC_PARAMS parameter + consisting of allocated input buffer, output buffer and output events in successive + ::NvEncEncodePicture() API calls along with other required encode picture params. + For example: + 1st EncodePicture parameters - (I1, O1, E1) + 2nd EncodePicture parameters - (I2, O2, E2) + 3rd EncodePicture parameters - (I3, O3, E3) + + b) NvEncodeAPI SW will receive the following encode Commands from the client. + The left side shows input from client in the form (Input buffer, Output Buffer, + Output Event).

These copies are done as part of nvEncEncodePicture + function call from the client and NvEncodeAPI interface is responsible for + synchronization of copy operation with the actual encoding operation. + I1 --> NvI1 + I2 --> NvI2 + I3 --> NvI3 + + d) The NvEncodeAPI encodes I1 as P frame and submits I1 to encoder HW and returns ::NV_ENC_SUCCESS. + The NvEncodeAPI tries to encode I2 as B frame and fails with ::NV_ENC_ERR_NEED_MORE_INPUT error code. + The error is not fatal and it notifies client that I2 is not submitted to encoder immediately. + The NvEncodeAPI encodes I3 as P frame and submits I3 for encoding which will be used as backward + reference frame for I2. The NvEncodeAPI then submits I2 for encoding and returns ::NV_ENC_SUCESS. + Both the submission are part of the same ::NvEncEncodePicture() function call. + + e) After returning from ::NvEncEncodePicture() call , the client must queue the output + bitstream processing work to the secondary thread. The output bitstream processing + for asynchronous mode consist of first waiting on completion event(E1, E2..) + and then locking the output bitstream buffer(O1, O2..) for reading the encoded + data. The work queued to the secondary thread by the client is in the following order + (I1, O1, E1) + (I2, O2, E2) + (I3, O3, E3) + Note they are in the same order in which client calls ::NvEncEncodePicture() API + in \p step a). + + f) NvEncodeAPI interface will do the re-ordering such that Encoder HW will receive + the following encode commands: + (NvI1, O1, E1) ---P1 Frame + (NvI3, O2, E2) ---P3 Frame + (NvI2, O3, E3) ---B2 frame + + g) After the encoding operations are completed, the events will be signaled + by NvEncodeAPI interface in the following order : + (O1, E1) ---P1 Frame ,output bitstream copied to O1 and event E1 signaled. + (O2, E2) ---P3 Frame ,output bitstream copied to O2 and event E2 signaled. + (O3, E3) ---B2 Frame ,output bitstream copied to O3 and event E3 signaled. + + h) The client must lock the bitstream data using ::NvEncLockBitstream() API in + the order O1,O2,O3 to read the encoded data, after waiting for the events + to be signaled in the same order i.e E1, E2 and E3.The output processing is + done in the secondary thread in the following order: + Waits on E1, copies encoded bitstream from O1 + Waits on E2, copies encoded bitstream from O2 + Waits on E3, copies encoded bitstream from O3 + + -Note the client will receive the events signaling and output buffer in the + same order in which they have submitted for encoding. + -Note the LockBitstream will have picture type field which will notify the + output picture type to the clients. + -Note the input, output buffer and the output completion event are free to be + reused once NvEncodeAPI interfaced has signaled the event and the client has + copied the data from the output buffer. + + * \endcode + * + *\par Synchronous Encoding + * The client can enable synchronous mode of encoding by setting + * NV_ENC_INITIALIZE_PARAMS::enableEncodeAsync to 0 in ::NvEncInitializeEncoder() API. + * The NvEncodeAPI interface may return ::NV_ENC_ERR_NEED_MORE_INPUT error code for + * some ::NvEncEncodePicture() API calls when NV_ENC_INITIALIZE_PARAMS::enablePTD + * is set to 1, but the client must not treat it as a fatal error.

The NvEncodeAPI interface will need to + keep a copy of the input buffers for re-ordering and it allocates following + internal buffers (NvI1, NvI2...). These internal buffers are managed by NvEncodeAPI + and the client is not responsible for the allocating or freeing the memory of + the internal buffers. + + The client calls ::NvEncEncodePicture() API with input buffer I1 and output buffer O1. + The NvEncodeAPI decides to encode I1 as P frame and submits it to encoder + HW and returns ::NV_ENC_SUCCESS. + The client can now read the encoded data by locking the output O1 by calling + NvEncLockBitstream API. + + The client calls ::NvEncEncodePicture() API with input buffer I2 and output buffer O2. + The NvEncodeAPI decides to encode I2 as B frame and buffers I2 by copying it + to internal buffer and returns ::NV_ENC_ERR_NEED_MORE_INPUT. + The error is not fatal and it notifies client that it cannot read the encoded + data by locking the output O2 by calling ::NvEncLockBitstream() API without submitting + more work to the NvEncodeAPI interface. + + The client calls ::NvEncEncodePicture() with input buffer I3 and output buffer O3. + The NvEncodeAPI decides to encode I3 as P frame and it first submits I3 for + encoding which will be used as backward reference frame for I2. + The NvEncodeAPI then submits I2 for encoding and returns ::NV_ENC_SUCESS. Both + the submission are part of the same ::NvEncEncodePicture() function call. + The client can now read the encoded data for both the frames by locking the output + O2 followed by O3 ,by calling ::NvEncLockBitstream() API. + + The client must always lock the output in the same order in which it has submitted + to receive the encoded bitstream in correct encoding order. + + * \endcode + * + * \param [in] encoder + * Pointer to the NvEncodeAPI interface. + * \param [in,out] encodePicParams + * Pointer to the ::_NV_ENC_PIC_PARAMS structure. + * + * \return + * ::NV_ENC_SUCCESS \n + * ::NV_ENC_ERR_INVALID_PTR \n + * ::NV_ENC_ERR_INVALID_ENCODERDEVICE \n + * ::NV_ENC_ERR_DEVICE_NOT_EXIST \n + * ::NV_ENC_ERR_UNSUPPORTED_PARAM \n + * ::NV_ENC_ERR_OUT_OF_MEMORY \n + * ::NV_ENC_ERR_INVALID_PARAM \n + * ::NV_ENC_ERR_INVALID_VERSION \n + * ::NV_ENC_ERR_ENCODER_BUSY \n + * ::NV_ENC_ERR_NEED_MORE_INPUT \n + * ::NV_ENC_ERR_ENCODER_NOT_INITIALIZED \n + * ::NV_ENC_ERR_GENERIC \n + * + */ +NVENCSTATUS NVENCAPI NvEncEncodePicture (void* encoder, NV_ENC_PIC_PARAMS* encodePicParams); + + +// NvEncLockBitstream +/** + * \brief Lock output bitstream buffer + * + * This function is used to lock the bitstream buffer to read the encoded data. + * The client can only access the encoded data by calling this function. + * The pointer to client accessible encoded data is returned in the + * NV_ENC_LOCK_BITSTREAM::bitstreamBufferPtr field.

use at your own risk + + Before #including, + + #define STB_IMAGE_WRITE_IMPLEMENTATION + + in the file that you want to have the implementation. + + Will probably not work correctly with strict-aliasing optimizations. + +ABOUT: + + This header file is a library for writing images to C stdio or a callback. + + The PNG output is not optimal; it is 20-50% larger than the file + written by a decent optimizing implementation; though providing a custom + zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that. + This library is designed for source code compactness and simplicity, + not optimal image file size or run-time performance. + +BUILDING: + + You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h. + You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace + malloc,realloc,free. + You can #define STBIW_MEMMOVE() to replace memmove() + You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function + for PNG compression (instead of the builtin one), it must have the following signature: + unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality); + The returned data will be freed with STBIW_FREE() (free() by default), + so it must be heap allocated with STBIW_MALLOC() (malloc() by default), + +UNICODE: + + If compiling for Windows and you wish to use Unicode filenames, compile + with + #define STBIW_WINDOWS_UTF8 + and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert + Windows wchar_t filenames to utf8. + +USAGE: + + There are five functions, one for each image file format: + + int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); + int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); + + void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically + + There are also five equivalent functions that use an arbitrary write function. You are + expected to open/close your file-equivalent before and after calling these: + + int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); + + where the callback is: + void stbi_write_func(void *context, void *data, int size); + + You can configure it with these global variables: + int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE + int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression + int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode + + + You can define STBI_WRITE_NO_STDIO to disable the file variant of these + functions, so the library will not use stdio.h at all. However, this will + also disable HDR writing, because it requires stdio for formatted output. + + Each function returns 0 on failure and non-0 on success. + + The functions create an image file defined by the parameters. The image + is a rectangle of pixels stored from left-to-right, top-to-bottom. + Each pixel contains 'comp' channels of data stored interleaved with 8-bits + per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is + monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. + The *data pointer points to the first byte of the top-left-most pixel. + For PNG, "stride_in_bytes" is the distance in bytes from the first byte of + a row of pixels to the first byte of the next row of pixels. + + PNG creates output files with the same number of components as the input. + The BMP format expands Y to RGB in the file format and does not + output alpha. + + PNG supports writing rectangles of data even when the bytes storing rows of + data are not consecutive in memory (e.g. sub-rectangles of a larger image), + by supplying the stride between the beginning of adjacent rows. The other + formats do not. (Thus you cannot write a native-format BMP through the BMP + writer, both because it is in BGR order and because it may have padding + at the end of the line.) + + PNG allows you to set the deflate compression level by setting the global + variable 'stbi_write_png_compression_level' (it defaults to 8). + + HDR expects linear float data. Since the format is always 32-bit rgb(e) + data, alpha (if provided) is discarded, and for monochrome data it is + replicated across all three channels. + + TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed + data, set the global variable 'stbi_write_tga_with_rle' to 0. + + JPEG does ignore alpha channels in input data; quality is between 1 and 100. + Higher quality looks better but results in a bigger image. + JPEG baseline (no JPEG progressive). + +CREDITS: + + + Sean Barrett - PNG/BMP/TGA + Baldur Karlsson - HDR + Jean-Sebastien Guay - TGA monochrome + Tim Kelsey - misc enhancements + Alan Hickman - TGA RLE + Emmanuel Julien - initial file IO callback implementation + Jon Olick - original jo_jpeg.cpp code + Daniel Gibson - integrate JPEG, allow external zlib + Aarni Koskela - allow choosing PNG filter + + bugfixes: + github:Chribba + Guillaume Chereau + github:jry2 + github:romigrou + Sergio Gonzalez + Jonas Karlsson + Filip Wasil + Thatcher Ulrich + github:poppolopoppo + Patrick Boettcher + github:xeekworx + Cap Petschulat + Simon Rodriguez + Ivan Tikhonov + github:ignotion + Adam Schackart + Andrew Kensler + +LICENSE + + See end of file for license information. + +*/ + +#ifndef INCLUDE_STB_IMAGE_WRITE_H +#define INCLUDE_STB_IMAGE_WRITE_H + +#include <stdlib.h> + +// if STB_IMAGE_WRITE_STATIC causes problems, try defining STBIWDEF to 'inline' or 'static inline' +#ifndef STBIWDEF +#ifdef STB_IMAGE_WRITE_STATIC +#define STBIWDEF static +#else +#ifdef __cplusplus +#define STBIWDEF extern "C" +#else +#define STBIWDEF extern +#endif +#endif +#endif + +#ifndef STB_IMAGE_WRITE_STATIC // C++ forbids static forward declarations +STBIWDEF int stbi_write_tga_with_rle;
