Captured texture is submitted to Media Foundation to encode video to mp4 file with\nhardware accelerated codec. Using capture from compositor and hardware accelerated encoder allows it to consume very\nlittle CPU and memory.\n\nYou can choose in settings to capture only client area or full size of window - client area will not include title bar and\nborders for standard windows style. Recorded video size is determined by initial window size.\n\nBy default hardware encoder is enabled, you can disable it in settings Make sure your GPU drivers are updated if something is\nnot working with hardware video encoding. Then video will be encoded using [Microsoft Media Foundation H264][MSMFH264]\nsoftware encoder. You might want to explicitly use software encoder on older GPU's as their hardware encoder quality is not great.\n\nAudio is captured using [WASAPI loopback recording][] and encoded using [Microsoft Media Foundation AAC][MSMFAAC] encoder, or\nundocumented Media Foundation FLAC encoder (it seems it always is present in Windows 10 and 11).\n\nRecorded mp4 file can be set to use fragmented mp4 format in settings (only for H264 codec). Fragmented mp4 file does not\nrequire \"finalizing\" it. Which means that in case application or GPU driver crashes or if you run out of disk space then\nthe partial mp4 file will be valid for playback. The disadvantage of fragmented mp4 file is that it is a bit larger than\nnormal mp4 format, and seeking is slower.\n\nYou can use settings dialog to restrict max resolution of video - captured image will be scaled down to keep aspect ratio\nif you set any of max width/height settings to non-zero value. Similarly framerate of capture can be reduced to limit\nmaximum amount of frames per second. Setting it to zero will use compositor framerate which is typically monitor refresh\nrate. Lower video framerate will give higher quality video for same bitrate and reduced GPU usage. If you notice too many\ndropped frames during recording, try reducing video resolution and framerate.\n\nCapture of mouse cursor can be disabled only when using Windows 10 version 2004, May 2020 Update (20H1) or newer.\n\nOn Windows 11 you can disable yellow recording borders, or rounded window corners. On Windows 11 24H2 version can enable secondary\nwindow capture, when they intersect main window in window-only capture mode - for popups \u0026 tool windows like \"Open File\" dialog.\n\nHEVC Software Encoding\n======================\n\nHEVC encoding in software (on CPU) will require installing HEVC Video Extensions from Windows Store. It will support only\n8-bit encoding. You can get direct download to installer package without using Windows Store application with following steps:\n\n1) open https://store.rg-adguard.net/\n2) search `https://www.microsoft.com/store/productId/9n4wgh0z6vhq` for `Retail` channel\n3) download \u0026 run .appxbundle package it gives you\n\nCreating gif from mp4\n=====================\n\nIf you want to create gif file out of recorded mp4 file, you can use following .bat file:\n\n    ffmpeg.exe -hide_banner -nostdin -loglevel fatal -stats -y -i %1 -filter_complex \"[0]fps=15,split[v0][v1];[v0]palettegen=stats_mode=full[p];[v1][p]paletteuse\" %~n1.gif\n\nOr to create new palette every frame for more colors, but larger file size:\n\n    ffmpeg.exe -hide_banner -nostdin -loglevel fatal -stats -y -i %1 -filter_complex \"[0]fps=15,split[v0][v1];[v0]palettegen=stats_mode=single[p];[v1][p]paletteuse=new=1\" %~n1.gif\n\nPut this line in `make_gif.bat` file, place [ffmpeg][] executable next to it and then simply drag \u0026 drop .mp4 file on top of it.\nChange `fps=15` to desired gif fps (or remove to use original video fps). Check the [paletteuse][] filter arguments for\ndifferent dither methods.\n\nBuilding\n========\n\nTo build the binary from source code, have [Visual Studio][VS] installed, and simply run `build.cmd`.\n\nLicense\n=======\n\nThis is free and unencumbered software released into the public domain.\n\nAnyone is free to copy, modify, publish, use, compile, sell, or distribute this software, either in source code form or as\na compiled binary, for any purpose, commercial or non-commercial, and by any means.\n\n[wcap-x64.exe]: https://raw.githubusercontent.com/wiki/mmozeiko/wcap/wcap-x64.exe\n[wcap-arm64.exe]: https://raw.githubusercontent.com/wiki/mmozeiko/wcap/wcap-arm64.exe\n[wgc]: https://blogs.windows.com/windowsdeveloper/2019/09/16/new-ways-to-do-screen-capture/\n[MSMFH264]: https://docs.microsoft.com/en-us/windows/win32/medfound/h-264-video-encoder\n[VS]: https://visualstudio.microsoft.com/vs/\n[WASAPI loopback recording]: https://docs.microsoft.com/en-us/windows/win32/coreaudio/loopback-recording\n[MSMFAAC]: https://docs.microsoft.com/en-us/windows/win32/medfound/aac-encoder\n[ffmpeg]: https://ffmpeg.org/\n[paletteuse]: https://ffmpeg.org/ffmpeg-filters.html#paletteuse\n[H264/AVC]: https://en.wikipedia.org/wiki/Advanced_Video_Coding\n[H265/HEVC]: https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding\n[AV1]: https://en.wikipedia.org/wiki/AV1\n[AAC]: https://en.wikipedia.org/wiki/Advanced_Audio_Coding\n[FLAC]: https://en.wikipedia.org/wiki/FLAC\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmmozeiko%2Fwcap","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmmozeiko%2Fwcap","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmmozeiko%2Fwcap/lists"}
