| "readme": "#### [RecordRTC to Node.js](https://github.com/muaz-khan/WebRTC-Experiment/tree/master/RecordRTC/RecordRTC-to-Nodejs)\r\n\r\nThis experiment:\r\n\r\n1. Records audio/video separately as wav/webm\r\n2. POST them in single HttpPost-Request to Node.js (FormData)\r\n3. Node.js code saves them into disk\r\n4. Node.js code invokes ffmpeg to merge wav/webm in single \"webm\" file\r\n5. The merged webm file is returned and played on the end!\r\n\r\n=\r\n\r\n##### How to install this package?\r\n\r\nIn node.js command prompt window:\r\n\r\n1. Type `npm recordrtc`; it will install in \"node_modules\" directory\r\n2. `cd node_modules\\recordrtc` to locate the directory\r\n3. `node index` to start `http://localhost:8000/`\r\n\r\n=\r\n\r\n##### Windows Batch File (`merger.bat`)\r\n\r\n`merger.bat` file is executed to invoke ffmpeg functionalities:\r\n\r\n```\r\n@echo off\r\n\"C:\\ffmpeg\\bin\\ffmpeg.exe\" -i %1 -i %2 %3\r\n```\r\n\r\n**It is assumed that you already have installed ffmpeg on your system.** Though, EXE file is hard-coded to \"C:\\ffmpeg\\bin\\ffmpeg.exe\" however you can easily edit it according to your own installations.\r\n\r\n=\r\n\r\n##### How to install ffmpeg on windows?\r\n\r\n1. Download ffmpeg and extract ZIP file\r\n2. Rename extracted directory to \"ffmpeg\"\r\n3. Right click over \"My Computer\" icon and select \"Properties\" context-menu option\r\n4. Select \"Advance system settings\" from top-left section\r\n5. Click \"Environment Variables...\" button from \"Advanced\" tab\r\n6. Click \"New...\" button and in the \"Variable name\" box, enter \"Path\".\r\n7. In the \"Variable value\" box, enter extracted directory full URI e.g. \"C:\\ffmpeg\"\r\n8. Click \"OK\" and done!\r\n\r\nhttp://www.wikihow.com/Install-FFmpeg-on-Windows\r\n\r\n=\r\n\r\n##### How to test?\r\n\r\nIn the node.js command prompt window; type `node index`; then open `http://localhost:8000/`.\r\n\r\n=\r\n\r\n##### `index.html`\r\n\r\n```html\r\n<!DOCTYPE html>\r\n<html>\r\n\t<head>\r\n\t\t<title>RecordRTC over Node.js</title>\r\n\t\t<script src=\"https://www.WebRTC-Experiment.com/RecordRTC.js\"> </script>\r\n\t</head>\r\n\t<body>\r\n <video id=\"camera-preview\" controls style=\"border: 1px solid rgb(15, 158, 238);
