[英]A simple C program to play mp3 using libvlc
I am an average C/C++ programmer.我是一个普通的 C/C++ 程序员。 Recently I took a project to make a media player with a smart playlist that will work like Zune's SmartDj.最近我做了一个项目,制作一个带有智能播放列表的媒体播放器,它可以像 Zune 的 SmartDj 一样工作。 I have decided to use libvlc for playing.我决定使用 libvlc 进行播放。
I have never coded an open source software before, so I know nothing about git and all.我以前从未编写过开源软件,所以我对 git 一无所知。 Can you please help me to write at least a C program to play a mp3 file?你能帮我至少写一个 C 程序来播放 mp3 文件吗?
Where should I get started?我应该从哪里开始? How do you extract a song's artist and other information from the mp3 file itself?您如何从 mp3 文件本身中提取歌曲的艺术家和其他信息?
regards.问候。
