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 (does it even work with vaapi in ffmpeg??). Would be very useful for steam deck. +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. @@ -103,12 +101,10 @@ Investigate if there is a way to do gpu->gpu copy directly without touching syst 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. @@ -152,17 +148,48 @@ Allow prime-run on x11 if monitor capture and the prime gpu is not nvidia. Enable 2-pass encoding. -Add cbr option. - Restart replay/update video resolution if monitor resolution changes. Fix pure vaapi copy on intel. -ffmpeg supports vulkan encoding now (h264!). Doesn't work on amd yet because mesa is missing VK_KHR_video_maintenance1, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/11857. Test on nvidia! - -Test vaapi low latency mode (setenv("AMD_DEBUG", "lowlatencyenc", true);), added in mesa 24.1.4, released on july 17, 2024. Note that this forces gpu power usage to max at all times, even when recording at 2 fps. Use nvidia low latency options for better encoding times. Test ideal async_depth value. Increasing async_depth also increased gpu memory usage a lot (from 100mb to 500mb when moving from async_depth 2 to 16) at 4k resolution. Setting it to 8 increases it by 200mb which might be ok. -Replace -encoder cpu with -k h264_software?
\ No newline at end of file +Replace -encoder cpu with -k h264_software? + +Change vp8/vp9 quality options, right now the file size is too large (for vp9 at least at very_high quality). + +Support recording while in replay mode. This will be needed when enabling replay on system startup with systemd service and wanting to record a video besides that. + The harder and more bloat solution for this would be to make an IPC. + The simple solution would be to use SIGUSR2 for starting/stopping recording since SIGUSR2 is unused for replays. That would mean SIGUSR2 for pausing recording would be ignored. + It also means that the video will be created in the same directory as the replay (or have option to specify another location for that) but the filename would have to be generated automatically. + To rename the file you would have to use -sc to rename it with a script, or add an option to provide a template for the name. + +Dynamically change bitrate/resolution to match desired fps. This would be helpful when streaming for example, where the encode output speed also depends on upload speed to the streaming service. +Implement opengl injection to capture texture. This fixes VRR without having to use NvFBC direct capture and also allows perfect frame timing. +Always use direct capture with NvFBC once the capture issue in mpv fullscreen has been resolved (maybe detect if direct capture fails in nvfbc and switch to non-direct recording. NvFBC says if direct capture fails). + +Support ROI (AV_FRAME_DATA_REGIONS_OF_INTEREST). + +Default to hevc if capture size is larger than 4096 in width or height. + +Set low latency mode on vulkan encoding. + +Support recording/replay/livestreaming at the same time by allowing commands to be run on an existing gpu screen recorder instance. + +Test if `xrandr --output DP-1 --scale 1.5` captures correct size on nvidia. + +Fix cursor position and scale when scaling x11 display. + +Support surround audio in application audio recording. Right now only stereo sound is supported. + +Support application audio recording without pulseaudio combined sink. + +Support transposing (rotating) with vaapi. This isn't supported on many devices with rgb buffer, but its supported with nv12 buffer (on intel at least). + +Cleanup pipewire_audio.c (proper error handling and memory cleanup of proxies). + +Hide application audio module-null-sink by using sink_properties=media.class="Audio/Sink/Internal". + +Improve software encoding performance. |
