VLC集成与使用

VLC的集成和使用

VLC介绍

VLC Media Player (VideoLAN) 为 Windows、Linux、OS X、Android、iOS、Windows Phone等平台提供一个视频播放器、解码器。它可以播放来自网络、摄像头、磁盘、光驱的文件，支持包括MPEG 1/2/4, H264, VC-1, DivX, WMV, Vorbis, AC3, AAC等格式的解码。在 Windows 和 Linux 上的 VLC 是使用C++/Qt写成，提供了一致的用户体验。同时 VLC 还专门为 OS X 提供了原生版本，OS X 版的 VLC 的用户界面使用Cocoa框架编写，在 OS X 下拥有卓越的原生体验。

• VLC还有一个非常好的功能——播放那些没有下载完整的视频文件。
• VLC几乎覆盖所有媒体格式。

VLC集成

在iOS下，我们可以很方便的使用VLC，因为它经行了优秀的封装，源码中最核心的部分被封装成了独立的库（MoblieVLVKit.framework库），它是基于FFmpeg，Live555提供完整的媒体播放库，所以整一个库体积还是比较大（目前已经超过600M了），不过并不会太影响App的大小，经行App打包发布的是会自动超级压缩的。经过测试它比使用FFmpeg库仅仅是多7M左右的大小。

• VLC cocoapods方式集成

VLC可以有多种的方式安装，目前最简单的方式就是cocoapods安装，以前需要下载源码后经行编译，编译后的还分模拟器版和真机版，最后还得使用lipo 命令经行合并，比较麻烦，这里我就不进行介绍了，因为没必要（喜欢折腾的可以自行搜索相关资料）,最终编译得到的结果一样是MoblieVLCKit.framework库，即使项目不允许使用cocoapods，也可以建立空项目后使用cocoapods得到MoblieVLCKit.framework在经行移植。

• 步骤

```objc
1.在podfile中写入：pod 'MobileVLCKit'
2.终端执行pod install即可（成功后会在项目里看到MoblieVLCKit.framework库）
3.添加依赖库：libz.tbd、libbz2.tbd、libiconv.tbd、libstdc++.6.0.9.tbd
```

VLC使用

MoblieVLCKit为我们提供了很多功能接口，不过我们不需要全部了解，只需要懂得几个常用的API接口就可以轻轻松松的写出一个播放器出来。因为它支持定制化UI，所以有心的开发者可以结合漂亮的UI设计一套专属的播放器

• MoblieVLCKit 常用API介绍
  • VLCMediaPlayer

    VCL对象，管理着播放的开始暂停等操作，有着几个代理方法可以经行状态和时间的监听回调
    

  • VLCMediaPlayer属性

    // 播放设置，比如设置播放路径是本地播放还是网络播放，以及播放的画面映射到哪个View
    

  @property (NS_NONATOMIC_IOSONLY, strong) VLCMedia *media;

  - VLCMediaPlayer方法
  ```objc
  // 开始播放
  -(BOOL)play;
  // 暂停播放
  - (void)pause;
  // 停止播放
  - (void)stop;
  /**
    *快进播放
    *interval:需要快进的秒数
  */
  - (void)jumpForward:(int)interval;
  /**
    *快退播放
    *interval:需要快退的秒数
  */
  - (void)jumpBackward:(int)interval;
  // 短时间的快退（10秒）
  - (void)shortJumpBackward;
  // 短时间的快进（10秒）
  - (void)shortJumpForward;
  /**
    * 以一定倍速播放
    * rate：倍速
  */
  - (void)fastForwardAtRate:(float)rate;
  

  • VLCMediaPlayer代理

    // 播放状态改变的回调
    - (void)mediaPlayerStateChanged:(NSNotification *)aNotification;
    // 播放时间改变的回调
    - (void)mediaPlayerTimeChanged:(NSNotification *)aNotification;
    

• MoblieVLCKit使用demo

我就抛砖迎玉贴上自己写的一份播放器demo封装(有时间我在放进github)
