阅读更多关于 Convert * (mp3, m4p, and the likes) to OGG via Command Line for HTML5 compatibility

问题 What options do I have for converting MP3's to OGG on the fly using PHP? I assume the only way to do this is via the command line with an execute statement. Is this true? If so, what converters (and associated commands) would I be best off using? I have tried: oggenc2.exe but was told by the program that the MP3 I passed was not a valid filetype ffmpeg.exe but was unable to figure out how to go from mp3 to ogg (found how to go from ogg to mp3 though) Convert mp3 to ogg via php 回答1: You didn't

阅读更多关于 Is it possible to read music file metadata using R?

问题 I've got a bunch of audio files (let's say ogg or mp3), with metadata. I wish to read their metadata into R so to create a data.frame with: file name file location file artist file album etc Any way you know of for doing that ? 回答1: You take an existing mp3 or ogg client, look at what library it uses and then write a binding for said library to R, using the existing client as guide for that side -- and something like Rcpp as a guide on the other side to show you how to connect C/C++ libraries

Adding DLL reference to VB.NET project

阅读更多关于 Adding DLL reference to VB.NET project

问题 Just to start off, this question does seem very similar to another post Add the DLL (lame_enc.dll) reference to my project , but I haven't been able to successfully apply that answer. I am pretty new to VB.NET so it is very possible I'm simply missing something obvious. I am trying to link a DLL to a VB.NET 2010 project to allow my VB app to play *.ogg files.

阅读更多关于 CentOs 下安装 ffmpeg 以及添加 ogg 音频支持

简单介绍 FFmpeg 是一个自由软件，可以运行音频和视频多种格式的录影、转换、流功能 [1] ，包含了libavcodec ─这是一个用于多个项目中音频和视频的解码器库，以及libavformat——一个音频与视频格式转换库。（来自维基百科）安装前提由于在centos下使用 yum install ffmpeg 是找不到安装包的，所以需要通过其他方法来安装：（以下摘自网络 http://aqbjzxl.iteye.com/blog/1408478 ）一、安装ffmpeg 操作系统：centos 5.6 (一)安装编译环境 #yum install -y automake autoconf libtool gcc gcc-c++ (二)安装所需程序库的RPM包到 centos(因为centos自带的库中没有ffmpeg包，这里相当于是扩展) view plaincopy to clipboardprint? #rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm (三)安装 Install ffmpeg 等模块 yum -y install ffmpeg ffmpeg-devel 本人就是使用以上方法安装成功的。

问题 I was doing some audio analysis stuff with Jupyter and tried to play .ogg files with IPython.display.Audio . Since PyCharm often failed to open big .ipynb files, I mostly used web browser to view my Notebook files at localhost:8888 . This picture is what I get with Chrome. As you can see, FailToDisplay.ogg is taken from my work, the audio play bar is not activated. File-ACDC_-_Back_In_Black-sample.ogg and song sample.mp3 are all downloaded from Internet. The integrity of 3 files are all

问题 I am making a site which will have music playing on the site using HTML5 tags and was wondering if there was any way to protect the files from being downloaded? I am calling the music file through PHP and if needed it selects an OGG file for browsers that don't support MP3. The actual files are inaccessible to the public but the PHP file can be downloaded and played. I was wondering if there was anything I could do which would stop people downloading the file but allow it to be played through
