使用适用于 HEVC 的 NVIDIA 视频编解码器 SDK 12.2 提高视频质量 -编码功能 UHQ 调整信息：新的调整信息在延迟容忍用例中提供最佳质量（仅支持 HEVC）。前瞻级别：增加前瞻分析以提高质量（仅支持 HEVC）。时间滤波：帮助滤除噪音以提高压缩效率（仅支持 HEVC）。单向 B 帧：使用单向 B 帧代替 P 帧来提高质量，在延迟敏感用例中特别有用（仅支持 HEVC）。更高位深度编码：将 8 位内容编码为 10 位（支持 HEVC 和 AV1）。解码功能： SEI 消息提取：使用 nvcuvid 解析器时，从输入文件中提取 SEI 消息。

ffmpeg 7.0发布了 http://tieba.baidu.com/mo/q/checkurl?url=https%3A%2F%2Fgit.videolan.org%2F%3Fp%3Dffmpeg.git%3Ba%3Dblob_plain%3Bf%3DChangelog%3Bhb%3Dn7.0&urlrefer=3bef97dcb5eb46fd22d404f42539a678

关于码率控制 VBR ■ Capped CRF ■ VBR ■ Capped VBR ■ Constrained VBR 你们一般会采用那种，原因是什么？

来自doom9的VVC测试情况 http://tieba.baidu.com/mo/q/checkurl?url=https%3A%2F%2Fdwzz.cn%2Fj8Il3A&urlrefer=c31baa27a58bf5540937f2da0cc3dffd The following inputs have been produced from TX Ready XDCAM-50 files: Sample 1: ColorBars FULL HD H266 YV12 BT709 SDR 10bit.ts Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts The decoding has been carried out using the following hardware: A) Intel Xeon E5-2637 v4 3.50GHz dual socket 8c/16th, 64GB RAM B) Intel i7 5930K 3.50GHz single socket 6c/12th 32GB RAM C) Intel Xeon Gold 6238R 2.20GHz dual socket 56c/112th 128GB RAM The tests have been conducted both using FFMpeg's new decoder and Fraunhofer's VVDec standalone decoder (i.e WITHOUT using the FFMpeg integration patch). Colorbars have been skipped in the benchmark decoding test due to the fact that it's quite literally the same frame repeated all over again and it would yield no significant speed outcome. Now, on to the FFMpeg decoder results: Intel Xeon E5-2637 v4 3.50GHz dual socket 8c/16th, 64GB RAM Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU constantly at around 89-100% fps= 35 Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts CPU oscillated between 78% and 93% without ever touching full 100%. fps=194 Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU oscillated between 41% to 76% without ever touching full 100%. fps= 24 Intel i7 5930K 3.50GHz single socket 6c/12th 32GB RAM Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps= 34 Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=193 Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU oscillated between 65% and 93% with occasional very rare spikes to 100% fps= 28 Intel Xeon Gold 6238R 2.20GHz dual socket 56c/112th 128GB RAM Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 23% overall with cores being used on one single socket fps= 44 Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 13% overall with cores being used on one single socket fps=249 Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 18% overall with cores being used on one single socket fps= 26 And now on to the VVDec results: Intel Xeon E5-2637 v4 3.50GHz dual socket 8c/16th, 64GB RAM Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=111 Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=618 Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=119 Intel i7 5930K 3.50GHz single socket 6c/12th 32GB RAM Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=108 Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=634 Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 100% fps=115 Intel Xeon Gold 6238R 2.20GHz dual socket 56c/112th 128GB RAM Sample 2: Chicago Fire FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 65% on one single socket fps=226 Sample 3: Judas and the Black Messiah SD H266 Main10 3Mbits 25p YV12 BT601 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 55% on one single socket fps=722 Sample 4: The Creator FULL HD H266 Main10 12Mbits 25p YV12 BT709 SDR 10bit AC3 2ch 48000Hz.ts CPU steadily at 66% on one single socket fps=211 This shows that not only VVDec is more optimized and makes use of the CPU resources in a better way (being able to scale even with CPUs that have a lot of cores, although not quite in every dual socket configuration) but the fps results tell the whole story, it's just faster. Before I made some claims about libav (i.e FFMpeg) being faster, however that was truly a mistake in my testing as it was just me not using VVDec directly but rather through an old unapproved patch via FFMpeg which was totally not optimized. Now that I compared libav via FFMpeg and VVDec using the native Fraunhofer executable, the whole story is completely different and VVDec appears to be miles ahead. On top of that, upon further testing, I had to throw away some samples as they reported the following error while trying to decode them with libav/FFMpeg: frame 78, P( 14, 1) failed with -1163346256 Intra Block CopyIntra Block Copy is not implemented. your file has a feature which has not been implemented. Decoding error: Not yet implemented in FFmpeg, patches welcome yet, VVDec managed to decode even those files without the blink of an eye. Nonetheless, here are the results of my tests:

玩家普及 Windows 11 的速度远逊于 Windows 10 微软已经一段时间没有披露 Windows 11 的普及率数据了，在发布半年之后，来自不同来源的数据都显示其普及率远逊于 Windows 10 同期水平。以最大的 PC 游戏平台 Steam 为例：Windows 10 发布半年之后普及率达到了 31%，而 Windows 11 只有 17%，Steam 统计的四分之三的计算机仍然运行 Windows 10。 Windows 11 硬件需求过高是影响它普及率的一个重要因素，许多旧电脑都无法升级到新系统，因此它的后续增长依赖于新计算机的采购。另一个重要因素是 Windows 10 取代的是不怎么受欢迎的 Windows 8 和 Windows 8.1，而 Windows 11 所取代的 Windows 10 很多用户都是相当满意的。 http://tieba.baidu.com/mo/q/checkurl?url=https%3A%2F%2Fwww.solidot.org%2Fstory%3Fsid%3D71254&urlrefer=b5e469fe3dddec5eebd372dad3aee170
