But since this project is mostly meant for Chinese user and rely on a Chinese website BiliBili (wikipedia), most things related to this project like code comments, documentations and other related repositories are written in Chinese. This README file will always use English so people like you can understand what is this, and perhaps make some use out of it.

Feature

• Easy to use
• Start recording automatically when stream starts
• Record multiple stream at same time
• Fix broken recording caused by broken bilibili stream server
• Toolbox mode to fix broken bilibili stream recording recorded by other software¹
• Pure C#, no native dependency like ffmpeg²
• Open source!

¹: Only unprocessed flv file downloaded directly from stream servers can be fixed. If the file is downloaded or processed by FFmpeg it no longer can be fixed, FFmpeg will fvck up the already broken recording even further.
²: A minimal version of FFmpeg is bundled with the desktop edition of BililiveRecorder for the remux feature in toolbox.
