@salmonwrap 你们这个没开硬件加速就不让看网页 4k 的限制是不是最近才加的啊，如果说我电脑之前硬件加速其实就没算开，但是我看 4k 也不卡啊，为啥要有这种限制啊。

@JackCh3ng 改回去又开始闪屏了，我太难了……

@salmonwrap
Choose ANGLE graphics backend 将这个选项改回去就可以了，但是当初刚改这个选项的时候没有引起这个问题，不知道是不是 Chrome 更新引起的。

我对比了一下 edge 和 chrome 的 gpu 信息，chrome 里 Video Acceleration Information Decoding 下面一项都没有了。
Video Acceleration Information
==============================
Decoding :
Encoding :
Encode h264 baseline : 32x32 to 1920x1088 pixels, and/or 30.000 fps.
Encode h264 baseline : 32x32 to 1088x1920 pixels, and/or 30.000 fps.
Encode h264 main : 32x32 to 1920x1088 pixels, and/or 30.000 fps.
Encode h264 main : 32x32 to 1088x1920 pixels, and/or 30.000 fps.
Encode h264 high : 32x32 to 1920x1088 pixels, and/or 30.000 fps.
Encode h264 high : 32x32 to 1088x1920 pixels, and/or 30.000 fps.
Encode av1 profile main: 32x32 to 1920x1088 pixels, and/or 30.000 fps.
Encode av1 profile main: 32x32 to 1088x1920 pixels, and/or 30.000 fps.

还有一些我觉得重要的不一样的信息
Chrome 里是这样的：
Graphics Feature Status
=======================
* Canvas: Hardware accelerated
* Canvas out-of-process rasterization: Disabled
* Direct Rendering Display Compositor: Disabled
* Compositing: Hardware accelerated
* Multiple Raster Threads: Enabled
* OpenGL: Enabled
* Rasterization: Unavailable
* Raw Draw: Disabled
* Skia Graphite: Disabled
* Video Decode: Hardware accelerated
* Video Encode: Hardware accelerated
* Vulkan: Disabled
* WebGL: Hardware accelerated
* WebGL2: Hardware accelerated
* WebGPU: Hardware accelerated
……

Problems Detected
=================
* GPU rasterization should only be enabled on NVIDIA, Intel, AMD RX-R2 GPUs with DX11+, certain QC devices+drivers or any GPU using ANGLE's GL backend.:
( http://crbug.com/1047002), ( http://crbug.com/1462800)
Disabled Features: gpu_tile_rasterization

* Some drivers are unable to reset the D3D device in the GPU process sandbox
Applied Workarounds: exit_on_context_lost


Edge 里：
Graphics Feature Status
=======================
* Canvas: Hardware accelerated
* Canvas out-of-process rasterization: Enabled
* Direct Rendering Display Compositor: Disabled
* Compositing: Hardware accelerated
* Multiple Raster Threads: Enabled
* OpenGL: Enabled

上面主要是这两项 Canvas out-of-process rasterization 和 Rasterization 不一致，还有 Chrome 里多了一项
* GPU rasterization should only be enabled on NVIDIA, Intel, AMD RX-R2 GPUs with DX11+, certain QC devices+drivers or any GPU using ANGLE's GL backend.:
( http://crbug.com/1047002), ( http://crbug.com/1462800)

@salmonwrap 好的，我回去看看

@salmonwrap 硬件加速是打开的，但是因为之前有显示器闪屏的问题，所以我将浏览器的 Chrome://flags 中的 Choose ANGLE graphics backend 这个选项手动选中为 OpenGL 了，不知道是不是这个原因，目前没办法测试。

你这题面上的 value 有做限制吗？如果你的例子里三个 id 的值都是 100 ，然后 n=2 ，请问要返回几个 id 呢？

我刚买了音箱，1000 块可以买个不错的音箱了。

你好，这是 Chrome 里的播放流水号
dcc4b01e5bbf49de88accdf8f18c432e 。
在 Chrome 里还是不行，只有客户端 4k 选项，选了之后弹下载客户端的弹窗。但是我试了用 edge 播放就可以有臻彩视听和 4k 超高清 sdr 选项了，选了之后可以正常播放。这是 edge 的播放流水号
