volume

In Android (using Java), how can I set the ring volume (to a specified number)?

青春壹個敷衍的年華 提交于 2019-12-05 14:57:14
So in my application, I have a seekbar that allows the user to set the ringer volume (0 - 100). I can't seem to find a way to set the ringer volume to a specified number. I looked through the AudioManager class but it tells me to either set ringermode to normal/silent/vibrate. That is NOT what I want. I want the volume to be a specific number . Here's an example of what I'm looking for: private void setRinger (int volume) // volume = 0 - 100 { setRingVolume (volume); // Whenever a person gets a call/sms/warning/anything etc., it should be this volume. } Is this possible in Android? If so, how?

pv(physical volume):对应物理磁盘 vg(volume group):由1个或多个物理硬盘组成 lv(logical volume):在vg上创建相应的逻辑分区,可以动态地扩大,缩小。将其格式化,mount到一个目录就成了可以直接访问的文件系统。 #lspv //查看所有的物理卷(物理磁盘) #lsvg //查看所有的卷组(物理磁盘组成) #lsvg -o //查看挂载成功的卷组 #lsvg -p glvg //查看glvg卷组包含哪些物理卷 #lsvg -l glvg //查看glvg卷组包含哪些逻辑卷 #lspv -l hdisk1 //查看hdisk1物理磁盘包含哪些逻辑卷 #lsvg rootvg //查看rootvg的详细信息 #lspv hdisk0 //查看hdisk0物理卷的详细信息 #lslv oralv2 //查看oralv2逻辑卷的详细信息 来源: https://www.cnblogs.com/zhxiaoxiao/p/11928175.html

Increase/Decrease audio volume using FFmpeg

怎甘沉沦 提交于 2019-12-05 10:07:02
I'm am currently using C# invokes to call the FFmpeg APIs to handle video and audio. I have the following code in place to extract the audio from a video and write it to a file. while (ffmpeg.av_read_frame(formatContext, &packet) >= 0) { if (packet.stream_index == streamIndex) { while (packet.size > 0) { int frameDecoded; int frameDecodedResult = ffmpeg.avcodec_decode_audio4(codecContext, frame, &frameDecoded, packet); if (frameDecoded > 0 && frameDecodedResult >= 0) { //writeAudio.WriteFrame(frame); packet.data += totalBytesDecoded; packet.size -= totalBytesDecoded; } } frameIndex++; }

Disable the Volume Toast

I'm trying to increase the volume using AudioManager. But it showing Native Android Volume UI(Volume Seekbar) toast.I want to disable this. I know this can be possible in Activity using Key Event but i want to do it through service. How to disable the toast? Here is a screenshot of the toast: The AudioManager -class offers the following methods to adjust the volume of certain streams: adjustVolume(int, int) adjustStreamVolume(int, int, int) adjustSuggestedStreamVolume(int, int, int) setStreamVolume(int, int, int) All those methods take a flag -parameter as their last argument. The flag which

Marching Cube Question

别等时光非礼了梦想. 提交于 2019-12-05 05:56:45
i currently writing a program to implement Marching Cube using C++ and Opengl. However, my best reference is only from http://local.wasp.uwa.edu.au/~pbourke/geometry/polygonise/ in the web, the provided codes are written in C. my problem here is that i don't understand the triTable and edgeTable and how they are related. can anyone help me on the explanation or guide me on converting the algorithm into codes? These Tables are used for finding out how to tesselate the surface: The first table gives you the necessary edges to interpolate. The second table gives you the way you have to tesselate,

Intersecting Volume in Matlab

匆匆过客 提交于 2019-12-05 05:56:07
问题 I have developed a code that takes a set of 3D coords, and performs triangulation to generate the convex hull/Delaunay . This has gone well and using the Deluanay triangulation I can test whether points are contained in a given volume using tsearchn. Now I want to take two of such 3D volumes, and test whether they intersect. Futhermore I would like to know what the percentage of volume A is intersected by Volume B. I think that I could generate a mesh grid of points that are within one of the

How do I edit the Default Volume?

问题 I'd like to set the default audio volume on the wordpress mediaelement.js player to be at 100% volume. It appears that the default is somewhere around 80%. Can anyone tell me which bit of code I need to change in order to do this? It'd be great if future versions of Wordpress come with a basic 'Settings' function for the now native player so we can alter thing like default volume and colours. 回答1: Got interested too with that question. So you have to go to your folder like: /wordpress/wp

概述 docker volume 命令 背景 docker 容器的存储, 通常需要独立于镜像 docker volume 就是负责这块的命令 1. 写在 docker volume 之前 概述 docker run 与 volume 相关的介绍 背景 其实在使用 docker [container] run 的时候, 我们已经在使用 volume 了 volume 概述 卷 卷 类似 linux 里的 卷 windows 里的 盘 作用 对接其他设备 拓展存储空间 隔离存储区域 对数据的迁移, 复用, 也有支持 1. 首先, 这个不是 volume 概述 docker run -v 中, 本地目录 与 容器路径 对接, 不是 volume 命令 > docker run --name some-nginx1 -v $(pwd)/html:/usr/share/nginx/html -d nginx 结果 容器成功启动 容器的 '/usr/share/nginx/html' 目录, 与 宿主机 的 '$(pwd)/html' 目录, 成功关联 但是 并没有创建 volume 验证 docker container inspect HostConfig 下 Volumes 字段, 值为 null docker volume ls 无法查到 新的 volume 特性 触发 填写路径时,

Pyaudio : how to check volume

I'm currently developping a VOIP tool in python working as a client-server. My problem is that i'm currently sending the Pyaudio input stream as follows even when there is no sound (well, when nobody talks or there is no noise, data is sent as well) : CHUNK = 1024 p = pyaudio.PyAudio() stream = p.open(format = pyaudio.paInt16, channels = 1, rate = 44100, input = True, frames_per_buffer = CHUNK) while 1: self.conn.sendVoice(stream.read(CHUNK)) I would like to check volume to get something like this : data = stream.read(CHUNK) if data.volume > 20%: self.conn.sendVoice(data) This way I could

How to display a volume with non-cubic voxels correctly in mayavi

只谈情不闲聊 提交于 2019-12-04 20:00:01
问题 I'm using mayavi (3.3.2) to display volume isosurfaces. Generally, my volumes do not have cubic voxels; for example, the sampling grid might be 1mm x 1mm in X and Y, but 1.4mm in the Z direction. How can I get such volumes to display with the correct spatial proportions using mayavi's mlab.contour3d or mlab.pipeline.iso_surface ? I'd really prefer to not resample the volumes to a cubic grid. Another way of stating the problem: what can I do to get the below code to display a sphere instead of
