调用处于无效状态的Android应用程序setOutputFormat：1 [英] Android application setOutputFormat called in an invalid state: 1

问题描述

Hiiii，



我正在开发一个在线视频流应用......我需要通过wifi将捕获的视频从一个Android设备发送到另一个设备.. .at目前我需要通过套接字连接流式传输捕获的视频，并将视频文件保存在其他设备中。我能够在设备之间建立套接字连接并保存离线视频......还可以捕获视频并保存sdcard中的视频文件...现在我必须在捕获视频时保存文件..

Hiiii,

I am developing a online video streaming application...i need to send the captured video from one android device to another device over wifi...at present i need to just stream the captured video over socket connection and save the video file in other device.. i am able to establish socket connection between the devices and save an offline video...and also capture the video and save the video file in sdcard...now i have to save the file while its capturing the video..

clientSocket = new Socket(SERVERIP,SERVERPORT);
                             pfd = ParcelFileDescriptor.fromSocket(clientSocket);
 mediaRecorder.setOutputFile(pfd.getFileDescriptor());

结果强制关闭申请并导致例外，因为





E / MediaRecorder（9341） ：setOutputFormat在无效状态下调用：1



即使我指定输出格式也是



mediaRecorder.setOutputFormat（MediaRecorder.OutputFormat.THREE_GPP）;



或者如果我删除也会得到相同的例外





并导致一系列错误和申请人关闭

It results in force close of an application and result in exception as


E/MediaRecorder(9341): setOutputFormat called in an invalid state: 1

even though if i specify the output format also

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);

or if i remove also i am getting the same exception


and results in a series of error and application force close
