我正在尝试迁移到Windows Server 2016,但我有问题。 nvfbc无法捕获以chrome格式播放的全屏视频 requiremens重现问题: Windows Server 2016 x64 quadro卡+电视连接到hdmi 369.49司机或任何其他人 chrome web浏览器 测试应用。 您甚至可以使用NvFBCHWEncode.exe(或任何其他示例)重现它 重现它的步骤: 开铬 2.进入高级设置,检查是否启用了hw加速(应该) 3.导航到您最喜爱的YouTube视频 4.关闭所有广告 5.启动NvFBCHWEncode.exe 6.使视频全屏并将鼠标移出屏幕 7.从pc断开任何vnc / teamviewer应用程序 8.在电视上观看视频30秒 9.检查由NvFBCHWEncode.exe创建的视频。 我现在看到的: 视频在某个时刻停滞不前(它反复重复一些帧) 任何事件的nvfbc更新框架(在广告上播放按钮弹出/鼠标移动) 我希望看到的内容: 从youtube录制的流畅视频。 我无法在win8.1上重现相同的问题。 以上来自于谷歌翻译 以下为原文 Hello Guys!

您可以尝试使用抓取超时消除“事件触发器”问题(如果有)。
fbcHwEncGrabFrameParams.dwWaitTime = 16; 以上来自于谷歌翻译 以下为原文 You can try to eliminate "event trigger" problem (if any) with grab timeout. fbcHwEncGrabFrameParams.dwWaitTime = 16; |

嘿mcerveny :)
ofcource我试着这样做。 它在超时后使用最后一个可用图像作为源。 问题是:如果“chrome正在运行全屏视频”,则“nvfbc无法捕获屏幕”。 我看到视频正在电视上播放(HDMI),但nvfbc没有制作任何帧。 我试图更改超时参数 - >(无等待/无限等待)它无法捕获屏幕。 没有报告任何错误。 没有“受保护的来源”或任何其他错误。 我需要捕捉改变的图片:D我不需要任何重复的图片:D 如果你愿意,我可以用手机录制这个问题的视频...... 以上来自于谷歌翻译 以下为原文 Hey mcerveny :) ofcource I tried to do that. It uses last avaliable image as source after timeout. Issue is: if "chrome is running fullscreen video" then "nvfbc unable to capture screen". I see video is playing on TV (HDMI) but no frames were produced by nvfbc. I tried to change timeout param -> (no wait/infinity wait) it just unable to capture screen. No any error is reported. no "protected source" or any other error. I need to capture changed picture :D I don't need any duplicate pictures :D I may record video of this issue using phone if you like... |

“最后可用”表示“视频卡住 - 从头开始的相同图像”(例如,捕获问题)或“视频播放 - 图像是及时的”(例如,触发问题)。
也许最后一些提示--Win2016 / Quadro驱动程序 - 尝试版本375.86是第一个符合Video SDK 7.0和Capture SDK的视频SDK。 我对下一步的看法:如果这没有帮助你可以尝试https://nvidia.custhelp.com/app/utils/login_form/redirect/ask(但是MTTR~1年)和/或GRID-devtech-support @nvidia .com(但没有回应)(http://on-demand.gputechconf.com/gtc/2016/presentation/s6307-shounak-deshpande-get-to-know-the-nvidia-grid-sdk.pdf)和/ 或等待NVidia或#NCACA(http://www.nvidia.com/object/grid-advisory-council.html)的回答和/或加入#NCACA或签署NVidia NDA以获得威廉希尔官方网站 支持和更新的NDA 捕获SDK。 以上来自于谷歌翻译 以下为原文 "last available" means "video stuck - the same image from beginning" (eg. problem with capture) or "video playing - the image is right in time" (eg. problem with trigger). Maybe some last hint - Win2016/Quadro driver - try version 375.86 is the first qualified for Video SDK 7.0 and Capture SDK depends on Video SDK. My opinion for next step: If this does not help you can try https://nvidia.custhelp.com/app/utils/login_form/redirect/ask (but MTTR ~1 year) and/or GRID-devtech-support@nvidia.com (but no respond) (http://on-demand.gputechconf.com/gtc/2016/presentation/s6307-shounak-deshpande-get-to-know-the-nvidia-grid-sdk.pdf) and/or wait for answer here from NVidia or #NGCA (http://www.nvidia.com/object/grid-advisory-council.html) and/or join #NGCA or sign NVidia NDA to get access to technical support and newer NDA Capture SDK. |
