直播软件开发如何使用FFMPEG推流并保存在本地

            #region RTMP推流(**已成功推流至服务器**)
            Network.Create()
                .WithSource(inputPath)//inputPath可以改成获取设备的视频流
                .WithDest("rtmp://192.168.61.128/live/livestream")//可以根据自己的需求更新RTMP服务器地址
                .WithFilter(new X264Filter { ConstantQuantizer = 20 })
                .WithFilter(new ResizeFilter(Resolution.X720P))
                .Push();
