问题 I'm trying to write an application that controls the system volume on Windows 7 but I can't find any documentation on where IAudioEndpointVolume is located in the .NET class library. What is the full path? 回答1: The Core Audio API (where IAudioEndpointVolume is located) is not native to the .NET Framework. However, you can use this Codeplex project, which provides .NET wrappers for the Core Audio API. 回答2: IAudioEndpointVolume is part of the operating system API's, it's in a C++ dll. It doesn

How do I amplify sounds by a specified number of decibels in AS3?

由 谁说我不能喝 提交于 2019-12-10 11:04:20
问题 A few days ago, this was my question, and I found the answer. Maybe this will help someone else. A. The first part of the problem: can you amplify sound using Flash? The AS3 documentation for SoundTransform says this about the volume attribute: "The volume, ranging from 0 (silent) to 1 (full volume). At face value, this means you can only make sounds quieter. In fact, if you supply a value greater than one (1.0), sounds will be amplified. You risk saturating the sound and getting poor quality

Find volume of 3d peaks in matlab

由 我的未来我决定 提交于 2019-12-10 10:29:46
问题 right now I have a 3d scatter plot with peaks that I need to find the volumes for. My data is from an image, so the x- and y- values indicate the pixel positions on the xy-plane, and the z value is the pixel value for each pixel. Here's my scatter plot: scatter3(x,y,z,20,z,'filled') I am trying to find the "volume" of the peaks of the data, like drawn below: I've tried findpeaks() but it gives me many local maxima without the the two prominent peaks that I'm looking for. In addition, I'm

How to make a docker container directory accesible from host?

问题 I have a tomcat running in a docker container and would like to watch was is going on in the webapps directory from the docker host. Is it possible to do this by mounting a volume without setting up a sshd in the container and without starting a shell inside? 回答1: Instead of mounting volume, you could open a new bash in your running container with docker exec : docker exec -it <id of running container> bash That way, you can directly go to the folder managed by the webapp from within the

一、何为docker docker最早基于LXC实现（LinuX Container）从0.7版本以后开始去除LXC转而使用自行开发的libcontainer，从1.11开始，演进为runC和containerd;docker是go语言开发，基于Linux内核的cgroup,namespace以及AUFS类似的Union FS（联合文件系统）等技术，对进程进行封装隔离，属于操作系统层面的虚拟化技术，由于隔离的进程独立于宿主机和其他的隔离进程，因此也称其为容器。 docker在容器的基础上进行了进一步的封装从文件系统，网络互联到进程隔离等，极大简化了容器的创建和维护管理。使得docker技术比虚拟机技术更为轻便，快捷。 虚拟机与docker比较： 图片引用自网络 由上面的比较图可以看同样启动一个服务;虚拟机会多一层操作系统，而docker和宿主机共用内核系统;因此docker占用资源更少，资源利用率更高; 虚拟机与docker对比 docker优点总结： 高效的资源利用率 快速的启动 一致的运行环境 持续将会和部署 更轻松的迁移 便捷的维护和扩展 二、dcoker安装 系统要求：CentOS7.x_x64且安装Docker CE版本（社区版），不要使用epel仓库自带的docker docker从1.17后主要分docker-ce和docker-ee（企业版，你懂滴

iphone - MPMoviePlayerController - How can I decrease volume of the video programmatically

由 ぐ巨炮叔叔 提交于 2019-12-09 22:15:22
问题 I'm using MPMoviePlayerController to play a video which has audio as well. It's working fine. I'm hiding the default controls. So no controls are showing on the video. I want to place a slider on the video (I successfully placed a slider as well over the video). With the slider, I want to control the volume of the video that is being played. How can I control volume of video? 回答1: See the documentation for MPVolumeView. Here is a sample code that I use in my view controller. MPVolumeView

基于GFS实现KVM的高可用及热迁移

一、GlusterFS概述 GlusterFS (Gluster File System) 是一个开源的分布式文件系统，主要由 Z RESEARCH 公司负责开发。GlusterFS 是 Scale-Out 存储解决方案 Gluster 的核心，具有强大的横向扩展能力，通过扩展能够支持数PB存储容量和处理数千客户端。GlusterFS 借助 TCP/IP 或 InfiniBand RDMA 网络将物理分布的存储资源聚集在一起，使用单一全局命名空间来管理数据。GlusterFS 基于可堆叠的用户空间设计，可为各种不同的数据负载提供优异的性能。 GlusterFS 总体架构与组成部分如图1所示，它主要由存储服务器（Brick Server）、客户端以及 NFS/Samba 存储网关组成。不难发现，GlusterFS 架构中没有元数据服务器组件，这是其最大的设计这点，对于提升整个系统的性能、可靠性和稳定性都有着决定性的意义。 GlusterFS 支持 TCP/IP 和 InfiniBand RDMA 高速网络互联。 客户端可通过原生 GlusterFS 协议访问数据，其他没有运行 GlusterFS 客户端的终端可通过 NFS/CIFS 标准协议通过存储网关访问数据（存储网关提供弹性卷管理和访问代理功能）。 存储服务器主要提供基本的数据存储功能，客户端弥补了没有元数据服务器的问题

OpenGL stencil buffer OR operation?

由 余生颓废 提交于 2019-12-09 11:59:25
问题 I'm not sure if this is possible to do, but it's worth a shot. I'm using the stencil buffer to reduce overdraw for light volumes in a deferred renderer using this algorithm (when the camera is outside the volume): Using a cheap shader, draw back faces with depth testing set to LEQUAL, marking them in the stencil buffer. Using the expensive lighting shader, draw front faces with depth testing set to GEQUAL. This will cause only pixels within the light volume to be shaded. The problem with this

Batch: list available hard drives and work with chosen option

由 白昼怎懂夜的黑 提交于 2019-12-09 04:28:24
I would like to list all available, removable hard drives in a batch script and continue to work with the chosen option. I know there are options like wmic logicaldisk get caption,volumename to list the hard drives and SET /P M=Type 1 or 2 then press ENTER: IF %M%==1 GOTO One IF %M%==2 GOTO Two to create a menu. But how do I store the volumes in variables and list them in a menu? Something like: Choose from list: 1) D:\Harddrivename1 2) E:\Harddrivename2 Enter option: 2 Any help is appreciated! Here's a function that'll let you create an array of drives that are not of type 3 (fixed): rem //
