converter

I'm trying to convert aac/wav/wma audio files to mp3 with Xuggler in Java. Unfortunately, I have a big loss of quality. My input file size is about 7MB and my output file size is only 1,5MB. The sample rate is set to 44100 Hz, is there other parameters to set? Thank you for your answers. if (args.length <= 1) throw new IllegalArgumentException("must pass an input filename and output filename as argument"); IMediaWriter writer = ToolFactory.makeWriter(args[1]); String filename = args[0]; // Create a Xuggler container object IContainer container = IContainer.make(); // Open up the container if

How to get from a opencv Mat pointcloud to a pcl::pointcloud? The color is not important for me only the points itself. you can do this like: pcl::PointCloud<pcl::PointXYZ>::Ptr SimpleOpenNIViewer::MatToPoinXYZ(cv::Mat OpencVPointCloud) { /* * Function: Get from a Mat to pcl pointcloud datatype * In: cv::Mat * Out: pcl::PointCloud */ //char pr=100, pg=100, pb=100; pcl::PointCloud<pcl::PointXYZ>::Ptr point_cloud_ptr(new pcl::PointCloud<pcl::PointXYZ>);//(new pcl::pointcloud<pcl::pointXYZ>); for(int i=0;i<OpencVPointCloud.cols;i++) { //std::cout<<i<<endl; pcl::PointXYZ point; point.x =

public static T Convert<T>(String value) { return (T)Convert.ChangeType(value, typeof(T)); } public enum Category { Empty, Name, City, Country } Category cat=Convert<Category>("1");//Name=1 When I call Convert.ChangeType , the system throws an exception on the impossibility of conversion from String to Category. How to do the conversion? Maybe I need to implement any converter for my type? Use Enum.Parse method for this. public static T Convert<T>(String value) { if (typeof(T).IsEnum) return (T)Enum.Parse(typeof(T), value); return (T)Convert.ChangeType(value, typeof(T)); } .Net Core version :

I have started writing an application using nodejs and jade, but after a while my team decided to switch to Django. I would still like to use the web pages written using jade, without having to re-write them by hand. Does anyone know of a tool that transforms jade code into html? As far as I've seen, most of the tools involving jade concentrate on the opposite transformation. Jade is supposed to come with a command line utility that does exactly that. See here https://github.com/visionmedia/jade#jade1 Or see just above it for a make file that runs it. - Edit - it seems Jade was renamed to Pug

There is IP address: 66.102.13.19, and from this address as that received this address http://1113984275 But how? And how I can make this with the help of bash. For example, this service can do it, but I do not understand the algorithm. ip=66.102.13.19 IFS=. read -r a b c d <<< "$ip" printf '%s%d\n' "http://" "$((a * 256 ** 3 + b * 256 ** 2 + c * 256 + d))" By the way, the number in your question doesn't match the IP address. To convert a decimal to an IP: #!/bin/bash dec2ip () { local ip dec=$@ for e in {3..0} do ((octet = dec / (256 ** e) )) ((dec -= octet * 256 ** e)) ip+=$delim$octet delim
