C# 利用FluorineFx-4.0 RTMP-Server 真实可用

利用FluorineFx-4.0开发RtmpServer

效果展示

Rtmp客户端使用手机导播软件可以实现Rtmp推流，我用的是芯象导播。Rtmp接收流是自己写的服务。图片如下：

            table.RtmpPullKeys = new List<RtmpPushKey>();

            RtmpPushKey key = new RtmpPushKey();

            key.Channels.Add(channel);


            table.RtmpPullKeys.Add(key);
            Console.WriteLine("-------------------RtmpPush1111111111111111111");

            //开启Rtmp服务并注册回调
            FLApplication.Start(RtmpHandshakeIPPoint, table);

            }
        }

操作流程

1、启动Rtmp
2、等待Rtmp启动完成点击获取流按钮

遗留问题

项目目前对音频支持不好，音频播放我测试是卡顿的。后续会继续优化。

未来计划

1、优化音频
2、使用UDP转发音视频流包括乱序重拍、流控、丢包补偿（nack和Fec）

项目说明

未来开发的服务主要针对以下几个方向：
1、监控SDK方向
2、视频传输SDK
3、视频会议方向
