android手机直播推流

这个项目是手机的摄像头作为硬件，采集视频流信息，把视频流推流到rtmp服务器，然后在本地使用vlc打开推流的视频，如果可以收到视频流，则证明推流成功

直播
采集端：
音视频采集，视频处理（美颜，水印） 音视频编码压缩  把音视频封装FLV  TS
常用框架
AVFoundation:数据
GPUImage：美颜
FFmpeg： 音频压缩
X264：   视频压缩
libremp：  推流

服务器流程：
数据分发CDN  鉴黄  截屏:展示主播画面  录制视频 实时转码

流媒体服务器
常用服务器  SNS BMS  nginx

播放端流程
从FLV TS 分离中音视频数据  音视频解码  播放  聊天互动

播放端 观众
ijkplayer :播放 
FFmpeg: 视频解码
VideoToolbox：视频硬解码
AudioToolbox：音频硬解码

github上有现成的开源实现，
推流、美颜、水印、弹幕、点赞动画、
滤镜、播放都有。技术其实不是很难，
而且现在很多云厂商都提供SDK，
七牛云、金山云、乐视云、腾讯云、百度云、
斗鱼直播伴侣推流端，功能几乎都是一样的，没啥亮点，
不同的是整个直播平台服务差异和接入的简易性。
后端现在 RTMP/HTTP-FLV 清一色，App挂个源站直接接入云厂商或CDN就OK。

1.先看效果图：

手机多种滤镜的运行效果：

因为代码实在太多，所以贴了一个项目地址，大概30M

项目地址：https://github.com/wrs13634194612/Rtmp-Video-Android.git

贴一下主要的核心代码：

1.清单文件申请权限：打开摄像头，麦克风采集声音信息，

2.主界面

布局：

说明：核心功能都在library里面，这个main只是调用一下方法，最后，启动，点击publish,开始推流，然后我们在vlc打开网络推流，就可以收到视频数据啦

vlc怎么使用，请看我上一篇博客，大疆无人机推流：https://blog.csdn.net/cf8833/article/details/92840672
