It has the same basic functions, and most of the keyboard commands are the same. DVXA2 and Direct3D11 Video Processor with hardware de-interlacing for NV12, YUY2, P010 formats. I seem to recall @rossy saying something about d3d11 not being as conducive to this method. DXVA2 (native) versus DXVA2 (copy-back) DXVA implementations come in two variants: native and copy D3D11 features a video api which is basically DXVA2 with a slightly altered interface above. ID3D11VideoProcessor also has these types of members: At any time, the primary video stream can switch between interlaced and progressive content, and the number of substreams can change. e. Both give me 650-710 fps on a test video d3d11 native 5 % at very low frequency DXVA copyback 3 % at even lower clocks DXVA native 0. Possibly it would work with an -DXVA2 Native DX9 hardware decoding returns bad quality (blurred chroma) on Nvidia GPUs. A few months ago at work, I was tasked with developing a custom, low-latency video player. If he is using MPCVR in DX11 mode, he will get a prompt to change MPCVR settings to DX9. LAV Splitter Many users of Freemake Movie Converter heard of CUDA and DXVA technologies integrated into the software to speed up video conversion. Using LibAV for H. I use DXVA2 native for TV (smoother handling or errors in streams, better deinterlacing with madVR), DXVA2 copyback for SD/HD movies (no chroma loss with NVIDIA, allows madVR black bar detection to remove TV logos on 2. I’ve already got the pricing models we use running through DirectX and the shader pipeline and I’m very interested in performance. But using DXVA2 for decoding (copy back), my RX580 can't cope with BD UHD 4k: is there a way to detect black bands even with native DXVA and D3D11 decoding? 12th October 2020, 15:21 Thanks for this suggestion! Definitely a new thing for me to learn. However, DXVA2 native works now with EVR at 50fps, using only iGPU. 264 parser at hand to extract fields of the SPS and PPS structures and all slices of an encoded frame. Thread Tools.

Same with x11vk. mkv -c:v hevc_amf output. Play a VP9 video with --hwdec=d3d11va or --hwdec=dxva2 on an AMD GPU that supports it (e. dll) 4. From what I can tell, Quick Sync support implies DXVA support, but I'm not 100% sure on that. I throttled my laptop CPU to minimum (at full speed I have 1% CPU usage) and took 4 avi files. It will most likely be removed in the future. Is there a way to use Nvidia GPU for MadVR and still use DXVA2/D3D11 native in LAV with Intel iGPU to support hardware decoding HEVC 4k @ 50/60fps? D3D11 acceleration instead of DXVA2. (Windows) DirectX Video Acceleration (DXVA/DXVA2) is a Microsoft API that allows video decoding/encoding to be hardware-accelerated. SampleFormat member of the DXVA2_VideoSample structure Второй момент: «Захотелось узнать про LAV VIDEO — NVIDIA CUVID и DXVA2 NATIVE — второй в контекстном меню выбора пакета кодеков K-Lite Codec Pack (для моей видеокарты GeForce GTX 750Ti). This video will show the difference between the accelerated speed we can get by enabling the 2 mechanism, nvidia's CUDA Cores And Microsoft's DXVA technology D3D11 requires us to insert a barrier between those draws. D3D11 Automatic is Native. ffmpeg -y -hwaccel_output_format d3d11 -hwaccel d3d11va -i input. Find the full change log below. 264 streams with only DTS timestamps would play out of sync with DXVA2; Fixed: DXVA2 could crash on some MPEG-2 streams; Fixed: Improved compatibility with a few HEVC streams when using DXVA2; 0. In 2 cases - I had 5% CPU load with CUVID, 7-10% with DXVA-native and 25% with "none". Due to the fact that DXVA2 and D3D11 are standard APIs on Windows and provided by the OS, in theory NO vendor-specific consideration is needed (in reality, app-specific workarounds would likely be VLC media player today got a major update. But cuda-copy and nvdec-copy, work E For D3D11 - on bugged frame image will freeze right at it or after, playback timeline will be stopped. I'm getting the problem with 4K videos, HEVC codec. 39 movies), and D3D11 native when I watch UHD (best performance and quality) which is not often. You need a good understand of h. would it be possible, not sure how much work this is, to implement D3D11 decoding support instead of DXVA for Windows 10? would it be possible doesn't cost us much to support, and there are platforms (older AMD drivers) where D3D11VA is significantly worse than DXVA2. 265/HEVC, VP8, VP9, H. 2 drivers with Microsoft Direct3D 10-, 10. 0 does not use the IAMVideoAccelerator and IAMVideoAcceleratorNotify interfaces, because the decoder can access the DXVA 2. The rendering of the decoded frames is done entirely in D3D11 (via Direct2D). . So I would grab the latest nightly and test those modes and if they are working fine leave it at that. The most interesting aspects of D3D11VA are the ability to support HDR and Rec 2020 color, UWP support, and waitable Dxva2 and d3d11va are two video decoding accelerator. VLC Player, MPC-HC, etc. 3 % at idle mpcVR d3d11 d3d11 native 2% at idle 300mhz DXVA copyback 3 % at up to 1300 usually much lower DXVA native 1. This post is an attempt to explain NVIDIA CUDA and DXVA in plain English. vaapi is Linux-only as far as I know. According to the manual, dxva2 can result in video quality reduction, so I suggest changing it to d3d11va / d3d11va-copy if you're on highlight recovery strength performs considerably faster when paired with D3D11 Native hardware decoding in LAV Video compared to DXVA2 (copy-back). I have to build FFMPEG with --enable-dxva2 and --enable-hwaccel=h264_dxva2 ? or Zeranoe build I have never use Direct X, do I need Direct X knowledge, or ffmpeg with --enable-dxva2 and --enable For DXVA2 Native there are additional requirements: You must use one of the following video renderers: EVR Custom Presenter, EVR Sync, EVR, MPC Video Renderer, or madVR. 13023.

You should never use DXVA2 native, it’s not a lossless quality video decoder. Video game streaming Many users of Freemake Movie Converter heard of CUDA and DXVA technologies integrated into the software to speed up video conversion. Strangely, it's not listed here, but I'm pretty confident it's just missing because Windows automatically installed it (which it would only do for WHQL drivers). Don't enable deinterlacing unless the source is interlaced. 0 - 2014/10/03. I think I'm done with madVR after all the time I spent trying it before, rather go with something simpler. The following table lists the GUIDs that identify Direct3D 12 video decoding profiles. 264/AVC, H. D3D9: NVIDIA GeForce GTX 1650 with Max-Q Design(\. 这里通过对比potplayer的DXVA2模式和MPC-HC的D3D11模式，可以发现DXVA2模式在同样播放同一个视频的时候功耗确实偏低，但是低的并不多，只有0. D3D11 will be more modern and technically I am trying to test decoding a h264/h265 video (with just a single iframe) using DX11 and DXVA2. DirectX - Uses DirectX VA2 and D3D11. Then driver crash follows DXVA2 (native), and CPU rendering will just show partial frame corruption. This is on windows 7 so I probably have to interop between 2 d3d11 devices, one with 11. I'll change that setting to D3D11 in MPC-HC then, thanks! Wonder why the default's DXVA2-native. I'm using MPC video decoder with MPC-BE, and all decoders (DXVA2, D3D11 and D3D11CB) has this problem, but NVDEC doesn't. Junior Member. Hi All! I've been reconfiguring my HTPC and discovered that even though new versions of MadVR haven't been released in a while, it's website has The better GPU will obviously have significant performance boosts for me across a variety of tasks and applications, but one I was wondering about and can't seem to find any real information on is in ffmpeg tasks where I employ DXVA2 hardware decoding. Each structure describes one possible configuration for the decoder device. mp4 The parameter hwaccel_output_format will specify the raw data (YUV) format after decoding. hi, recently i found that when I use FFmpeg + DXVA2/D3D11VA accelerator to decode H264 1080P video. The reasoning for this, is I can then decode the YUV format directly on the GPU and then display it without having to Marshall it back to the CPU. Possible Fix. When using feature levels 9_x, all partially encrypted buffers must use the same EncryptedBlockInfo, and partial encryption cannot be turned off on a per frame basis. Reply reply [deleted] • Thanks LAV author said DXVA2 (copy-back)/d3d11 should usually be preferred over CUVID because of problems/limitations (though I don't know the details). AMD is using UVD in a strange way. My gameplay feels smooth!I realized I flinched playing the game expecting lag and FPS drops, which never came. Reply. Requirement Using DXVA Checker, it says that GPU supports hevc 10bit with both DXVA2/D3D11. To Reproduce. I'm not sure, but I think it used to work correctly. For QSV based decoding on Windows OS either DXVA2 (Direct-X Video Acceleration API) or D3D11VA (Direct 3D 11 Video API) support is required. SVP developers and other users reply with explanations and suggestions You should switch to D3D11 Automatic which is hardware accelerated like DXVA2, but it's a perfect quality lossless decoding. I compiled an official example hw_decode. Microsoft provides wrappers over hardware accelerated decoders in the format of Media Foundation API primitives, such as H. Playback. Describes the configuration of a Microsoft Direct3D 11 decoder device for DirectX Video Acceleration (DXVA). Excessive unrolling increases compile times and makes it harder for Vulkan drivers to optimize. It's DirectX 11 evolution is D3D11 Video Device part of D3D11 API. Maintainer - vk的问题faq里也早提到了，我已经引导他去完整看faq 了 D3D11 Decoding The main motivation behind offering D3D11 decoding is the ability to be able to process the resulting image on the GPU without any loss - something that was not always possible on DXVA2. See how they affect performance, post-processing and compatibility with MadVR and LAV Video. Requirements. ; During media type negotiation, the In Preferences go to Filter Control in the side tab and into the Video Decoder settings. Upon further investigation I saw that I receive a lot of "Invalid data found when processing input" errors when calling avcodec_send DXVA2 (DirectX Video Acceleration 2) 和 D3D11 (Direct3D 11) 是两个不同的API，用于在Windows平台上加速视频和图形处理。 DXVA2是一个用于视频解码加速的API，它可以在GPU上执行视频解码，从而减轻CPU的负担。 Hardware decoder to use -> D3D11 (win 8/10/11) or DXVA2 (copy-back) Hardware device to use -> Your_GPU_Device (leave on Auto with D3D11) Dithering mode -> Ordered dithering; Start -> K-lite Codec Pack -> LAV Audio D3D11（native）模式还行，封装功耗内显是10W出头，主要还是GPU相比DXVA2（native）多出了约1W的功耗 DXVA2（native）是最省电的，不过实际上整机功耗和D3D11（native）比降低幅度不算太大，两者都是可以接受的水平。 Many video playback applications (e.

It means you need configuring and building FFmpeg with the following options: The decoding happens part in hardware via DXVA2/Intel Media SDK and in part in sofware via ffmpeg. Intel® Media SDK provides an API to access hardware-accelerated video decode, encode and filtering on Intel® platforms with integrated graphics. That has similar performance as "DXVA2 Copyback", while "D3D11 Native" is faster with 4k content. AMD AMF: ffmpeg -hwaccel dxva2 DXVA2 (native): Can be used by any hardware that supports DXVA2 (Intel might have some issues with VC1 video). 264 bitstreams to proceed (really!). Code. Common Issues and Solutions. Subtitle and OSD display. Try CopyResource() instead of CopySubresourceRegion(). All reactions. However, not everyone knows how and when these technologies actually work and what The binding flags (BindFlags) should include the D3D11_BIND_DECODER flag and any bind flags set through the MF_SA_D3D11_BINDFLAGS attribute in the output stream attributes. To be able to actually leverage this, you'll need a renderer which also supports D3D11 input from a decoder - currently this is only madVR. The DX11 hardware decoding API (D3D11VA) that is used when LAV Video is set to D3D11 Automatic (so native decoding is We will likely have to support both DXVA2 and D3D11VA for the near future, even on Windows 10. During testing I noticed that I get some strange artefacts when using D3D11VA or DXVA2 hw acceleration. Constant buffers. Receives a pointer to the ID3D11VideoDecoder interface. While the hardware decoders produce textures in NV12 format directly, the software decoder has to upload the NV12-formated frames to GPU memory. 2: Minimum Windows version: 8: Driver implementation—Full graphics and Render only: Mandatory for all WDDM 1. Inheritance. 94: 1530. 51: 839. Expected behavior. Note that when you select a card instead of Automatic then you no longer use "D3D11 Native" but "D3D11 Copyback"! (I know it's a bit confusing). Closed Aleksoid1978 opened this issue Nov 10, 2020 · 0 comments Closed Yes dxinterop uses d3d9 to present the opengl surfaces. mkv > > D3D11va decoder (Using d3d11 native, since it's way faster than copyback. mp4 Hardware video decoding comes from DXVA (DXVA2) API. I'll test the Intel driver and LAV filters later. Faster: DXVA2 Copy-Back in direct output mode uses up to 50% less CPU and performance is improved accordingly; Fixed: H. 1-capable hardware (or later) DXVA2 hardware acceleration only works on Windows.

Steps to reproduce the behavior: Load a particular Video An emulation layer is provided that converts between either version of the API and the opposite version of the DDI: If the graphics driver conforms to the Windows Display Driver Model (WDDM), DXVA 1 API calls are converted to DXVA 2 DDI calls. NVIDIA CUVID + Reply to Thread. As I understand, this is infact possible. 3) LAV DXVA2 native performance, like MS MFT DXVA2/D3D11 native, is the lowest and copy-back is the highest, probably because clocks are pushed higher for 3D (copy-back) mode and it's lower than real-time (47fps vs 60fps) I didn't monitor GPU clocks, but i have no other explanation. 4001, released 12/16/21. To avoid raw data copy between GPU memory and system memory, use -hwaccel_output_format dxva2_vld when using DX9 and use -hwaccel_output_format d3d11 when Pass in the same decoder device GUID, along with a DXVA2_VideoDesc structure that describes the proposed output format. The DX11 hardware decoding API (D3D11VA) that is used when LAV Video is set to D3D11 Automatic (so native decoding is used), and madVR is set to use Direct3D 11, avoids these problems. mpv always fallback to software decoding when I set hwdec=d3d11va log file if you are interested log. Quote reply. 1 The DXVA2 option silently falls back to software decoding for both H. They each have their own way of parsing etc. to be more specified, the FPS can up to 400+ if use DXVA2, but is < 100 fps when using D3D11VA.

For example, here is NVidia capabilities (from june 2016 codec sdk) : Also, for NVidia, if you check this link Nvidia PureVideo, some widths can't be decode :. Your Intel GPU will be used by default if you use DXVA2. The following GUIDs support Direct3D 12 Video APIs. Joined Jul 14, 2014 Messages 7,154 Reaction score 3,519 Points 1,555 Location This sample is essentially a port of the DXVA2_VideoProc Sample. QuickSync does not offer any benefits. Then driver crash follows For DXVA2 (copy-back) - on bugged frame image will still freeze, but playback timeline WON'T be stopped. Aquí nos gustaría mostrarte una descripción, pero el sitio web que estás mirando no lo permite. There was a fix in LAV Filters today that solves a startup delay with D3D11 decoding. The pipeline allows certain CPU-intensive operations such as iDCT, motion compensation and deinterlacing to be offloaded to the GPU. Someone changes the LAV settings to DXVA2 Native. This decoder is offering use of hardware decoding capabilities as well as fallback to Emby only supports headless operation (and running as a service) with D311VA codecs. D3D11: MFX MSMF: D3D11-Hardware Use D3D11 or DXVA2 (copy-back). Command line options: Option Description-hh: Switch between windowed mode and full-screen mode. But i really don't know how to proceed. But if SMPlayer+mpv's video quality looks better than MPC-HC/BE and I notice it's darker, I'll look for gamma so thanks for that too! as he said use dxva2 or d3d11 instead. For example: VLC Player allows you to enable: QuickSync and/or DXVA; Freemake allows you to enable: CUDA and/or DXVA; What I am trying to understand is what is the relationship between hardware acceleration and these technologies? Can work with DXVA2 and Direct3D 11 hardware decoder. 0 Kudos Copy link. This is due to D3D11 Native's better optimization for DX11 D3D11 native, D3D11 copy-back, and DXVA2 copy-back are the only perfect quality decoders. Vulkan is a massive improvement . Dxva2 and D3d11 are almost exactly the same, except dxva2 uses d3d9 while D3d11 uses D3d11 functionality, the can both decode the exact same formats. You signed out in another tab or window. 8 How to properly use a hardware accelerated Media Foundation Source Reader to decode a video? 0 which h264 profile supported by dxva2 hardaware decoder. But the automatic detection of black bars in madvr doesn't work with DXVA2/D3D11 (native). The sample programmatically generates video with a primary stream Requirement Value; Minimum supported client: Windows 8 [desktop apps | UWP apps] Minimum supported server: Windows Server 2012 [desktop apps | UWP apps] A pointer to a D3D11_VIDEO_DECODER_DESC structure that describes the video stream and the decoder profile. In order to build FFmpeg with DXVA2 support, you need to install the dxva2api. d3d11 pixel format is not supported as input to h264_qsv encoder (should be qsv). I'm not sure if it's still true but I A user asks whether to use DXVA2 or D3D11 for SVP, a video frame rate conversion software. Results 1 to 1 of 1 HEVC acceleration: DXVA copy-back vs. This is showing up as a response to a question on intel vs intel vpp decoding. to iGPU, which now gives me This browser is no longer supported. This will improve transcoding speed greatly. On Windows I support D3D11VA, DXVA2 and Cuvid for hardware acceleration (and software decoding as fallback). Chainik; SVP developer; Offline; Thanks: 1629; 3) LAV DXVA2 native performance, like MS MFT DXVA2/D3D11 native, is the lowest and copy-back is the highest, probably because clocks are pushed higher for 3D (copy-back) mode and it's lower than real-time (47fps vs 60fps) I didn't monitor GPU clocks, but i have no other explanation. D3D9: Auto 3. EVR Simple + D3D11 CB direct - GPU Load 83 % EVR Custom + DXVA2N - GPU Load 55 % EVR Custom + DXVA2CB direct - GPU Load 67 % For example, it may ignore DXVA2 processing (resizing and colorspace conversion, unrelated to decoding!), which is used by EVR simple. Represents a video processor for Microsoft Direct3D 11. But I believe that issue is fixed. 0. Reload to refresh your session. Render directly after GPU decoding. Intel Beta - As it states, this is for Intel and is in Beta testing. Мы хотели бы показать здесь описание, но сайт, который вы просматриваете, этого не позволяет. 5. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. With DXVA2 and HDR (10-bit) both disabled: no crash, normal playback; Expected Behavior. I need to find why DXVA2 copy-back makes this lag. For D3D11, selecting your GPU from the dropdown is copy-back mode and selecting Automatic is native mode. I did the comparison on an i7-8700 desktop with UHD630 iGPU. Supported pixel formats: nv12 yuv420p p010le bgra bgr0 d3d11 dxva2_vld hevc_amf AVOptions: -usage <int> E. ) are highly configurable. Navi and likely also Raven Ridge/Renoir APUs). You switched accounts on another tab or window. I am back to using D3D11 Native hardware decoding in LAV Video rather than DXVA2 (copy-back). The QuickSync implementation in LAV is obsolete, outdated, and has no benefits over the other hardware acceleration choices. CUVID also does not offer any benefits. This is the best setting we recommend for transcoding. One of the reasons to use hardware accelerated decoding is to reduce power consumption. The SampleFormat. You signed in with another tab or window. Running OK with d3d11 + shaders shows me that the system can run it properly. If "Hardware decoder to use" DXVA2 or D3D11 = (copyback) is set, The Windows Driver version is 30. ) Note, that I don't use madvr's pixelshader hdr2sdr conversion, I use hdr passthrough. Only CPU (No acceleration) The DXVA2_VideoProc sample builds a Windows application. This is probably the cause of your problem. If I select any of them and try to work with any video then the video is glitched. I also did few simple CPU load tests on diffrent hardware acceleration settings CUVID vs DXVA vs none. When I Hi, I’ve just started looking into CUDA as an option. For example it was really bad on windows, Tried D3D11 automatic (with Nvidia GPU disabled, otherwise LAV refuses to use GPU altogether), but LAV still uses copyback. Shader video processor for various YUV, RGB and grayscale formats. 2 Hardware Accelerated H264 Decode using DirectX11 It depends on your GPU hardware capabalities. Interlacing can be done in madvr as well, but does not work with D3D11. DXVA2 for H. 99: 841. Drakko01; 哔哩哔哩 (゜-゜)つロ 干杯~-bilibili D3D9 and D3D11 are listed in Hardware Decoder Mode. For plain DXVA2 you will need to connect a physical monitor to the video output. 7,709 Views Mark as New; DXVA2 and D3D11 use the exact same hardware decoder on your Intel GPU. Olga Bulava Offline. Run in OpenGL ES2 mode (ANGLE) to enable 0-copy. Prior to this, I had worked only briefly with FFmpeg and not at all with DirectX 11. vo=gpu is redundant as it's enabled by default. 2#1440p#drivercomparisonFollow me on my Website, https://deseffekt. Look for a configuration that the decoder supports. In response to Mark9_Intel. Comment options {{title}} Something went wrong. 0 update codenamed “Vetinari” comes with several new improvements like HEVC hardware decoding on Windows, using DxVA2 and D3D11, support for 360 video and 3D audio, support for Chromecast streaming and more. In this article. cpp that process frames but I cannot figure out what the difference is between them. Core Support network browsing for distant filesystems (SMB, [] As discussed here, I feel that DXVA2 Copy-Back in LAV Video is a better choice than CUVID for hardware acceleration with Nvidia graphics cards. GstD3D11 plugin supports H. This plugin consists of various video filter, screen capture source, video sink, and video decoder elements. F1–F8: Enter one of the modes shown in the following table. In shader code, avoid unrolling large loops. 1-, 11-, or 11. I personally can't see a real difference in quality or performance, I asked because I thought one could perform better with SVP than the other. If I’ve already got the algorithms vectorized and take advantage of all On 13/04/18 10:21, Alexander Kravchenko wrote: > > This patch contains DXVA2 textures support implementation by AMF encoder (in addition of D3D11 textures) > > Samples of usage: > DXVA2 decoder -> dxva2_vld texture -> AMF Encoder: > ffmpeg -hwaccel dxva2 -hwaccel_output_format dxva2_vld -extra_hw_frames 16 -i input. The latest nightlies contain experimental dxva2 hw decoding through libavcodec Only h264/h265 **8** bits are supported Normally no, vdpau keeps the video on the video card as long as possible (which dxva does not, i think i'll need to go D3D11 to do that) It could be something else. Disabling HDR (apparently) removes the delay before the crash. The GPU also can run at different clock speeds depending on the load. I read that D3D11 uses DirectX 11 and DXVA2 uses DirectX 9, but they both should work similar. make sure you have a h. DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. i. PC User Offline. ProcessFrameUsingD3D11()uses VideoProcessorBlt() to actually do the render. g. Microsoft Direct3D11 plugin. The performance of D3D11VA is rather slow. I've briefly updated the code to be compatible with Qt6 hoping it could fix the audio, but no luck so far. CUVID forces the graphics card into its highest performance state. Encoder Usage (from 0 to 5) (default transcoding) transcoding 0 E. 28th Jul 2017 00:59 #1. I'm trying to get FFMPEG to output D3D11 2D textures directly as Frames. At the bottom of this section click on Built-in Video Codex/DXVA Settings (DirectX Video Acceleration, I didnt know what the acronym stood for) and look for DXVA2 Copy-Back. (A known problem). Use *SetConstantBuffers1 to bind sub-ranges of a larger constant buffer. D3D12_VIDEO_DECODE_PROFILE GUIDs. Opposite case. 264 videos using DirectX Video Acceleration 2 (DXVA2), Direct3D 11 (D3D11), and Video Acceleration API (VA) for hardware-accelerated decoding. DXVA2 native and CUVID degrade quality. Various frame resizing algorithms, including Super Resolution. Latest Git build, but it's been this way for as long as I've had my GTX 1050 (a few months) Windows 10 Reproduction steps Using hwdec=cuda or hwdec=nvdec in the mpv. 262/MPEG-2 video, and AV1 codecs for decoding as well as hardware-accelerated video deinterlacing. For QSV based encoding libmfx (Intel proprietary library that provides hardware based video encoding) support is required. (adding -loglevel debug we can see that the output of ddagrab is pixfmt:d3d11). And that's on an old ass computer that would literally drop to 20 hideout fps for Using DX11 and DXVA2. D3D11 consumes less resources. Has issues with Blu-ray support in MediaPortal 1 (dropped frames on clip boundaries as DXVA requires video decoder to flush few frames). yhysp yqgkj tpxlli ldmer giwlup qjnojyv flcsnw adbhj kncl flhft
