需要概要:实现视频拨打、接听、挂断、视频界面大小窗口、点击小窗口实现大小窗口调换。
实现思路:一方拨打后,另一方要能收到相应事件,而后接听。接通后,渲染对方视频画面。那么己方视频画面什么时候渲染呢?对于呼叫方,能够在呼叫后开始渲染,也能够接通事件事件产生后再开始渲染。对于接通方能够在点击接听按钮后开始渲染,也能够在接通事件产生后开始渲染。
有了上述思路,在模块文档中查找相应 api,编写代码,就能够验证咱们的思路是否能够实现。如果遇到问题,再调整实现思路。
以下是融云模块文档链接:https://docs.apicloud.com/Cli…
简要介绍用到的次要 API:
**startCall 发动音视频通话
addCallReceiveListener 音视频复电事件监听
accept 接听复电
addCallSessionListener 音视频通话事件的监听(蕴含响铃、接通、挂断等多个事件监听)setVideoView 设置视频区域
resetVideoView 重设视频区域
removeVideoView 移除视频区域
hangup 挂断 **
上面解说代码。
要调用音视频通话性能前应先调用 api.hasPermission 接口查看是否有麦克风、相机权限,如果没有,要先申请权限。
api.requestPermission({list: ['microphone', 'camera', 'storage', 'photos'],
code: 1
})
融云初始化胜利之后,可增加相应事件的监听。didReceiveCall 接到复电事件后,弹出接听页面。接听后,会执行到 didConnect 事件, 此时可设置本地窗口 setVideoView;稍后会执行到 remoteUserDidJoin(对端用户退出通话事件),此时能够通过 setVideoView 设置对端用户窗口。通过 videoViewBringToFront 接口将本地小窗口调整到最后方。
apiready = function () {rong = api.require('rongCloud2');
rong.init({huaweiPush: false}, function (ret, err) {if (ret.status == 'error') {
api.toast({msg: err.code});
} else {console.log('初始化胜利');
rong.setConnectionStatusListener(function (ret, err) {console.log("连贯状态监听:" + ret.result.connectionStatus);
});
// 收到复电事件监听
rong.addCallReceiveListener({target: 'didReceiveCall'}, function (ret) {console.log('didReceiveCall:' + JSON.stringify(ret))
callId = ret.callSession.callId;
api.toast({msg: '复电请接听'})
fnopenbtnframe(); // 关上接听、挂断按钮所在的 frame});
// 通话连贯胜利监听
rong.addCallSessionListener({target: 'didConnect'}, function (ret) {console.log('didConnect:' + JSON.stringify(ret))
var myname = api.getPrefs({
sync: true,
key: 'myname'
});
// 关上本地窗口
fnsetVideoView(api.winWidth - 200, 100, 160, 200, myname);
// 将本地窗口显示到最后方
setTimeout(function () {
rong.videoViewBringToFront({userId: myname})
}, 1000)
})
// 通话已完结的事件
rong.addCallSessionListener({target: 'didDisconnect'}, function (ret) {console.log('didDisconnect:' + JSON.stringify(ret))
})
// 对端用户退出了通话的事件
rong.addCallSessionListener({target: 'remoteUserDidJoin'}, function (ret) {console.log("对端用户退出了通话的事件:" + JSON.stringify(ret));
var uid = ret.userId;
// 设置远端窗口
fnsetVideoView(0, 0, api.winWidth, api.winHeight, uid);
});
// 监听视频区域点击事件,实现大小窗口切换
rong.addVideoViewListener(function (ret) {
// 判断点击的是否是初始小窗口
if (ret.userId == myname && meissmall) {fnresetVideoView(0, 0, api.winWidth, api.winHeight, ret.userId);
fnresetVideoView(api.winWidth - 200, 100, 160, 200, hename);
meissmall = false;
setTimeout(function () {
rong.videoViewBringToFront({userId: hename})
}, 1000)
setTimeout(function () {fnopenbtnframe()
}, 1200)
}
if (ret.userId == hename && !meissmall) {fnresetVideoView(0, 0, api.winWidth, api.winHeight, ret.userId);
fnresetVideoView(api.winWidth - 200, 100, 160, 200, myname);
meissmall = true;
setTimeout(function () {
rong.videoViewBringToFront({userId: myname})
}, 1000)
setTimeout(function () {fnopenbtnframe()
}, 1200)
}
})
}
});
};
实现成果如下:
其余经验总结:
返回错误码 34001,重启 loader 可解决,可能换账号登录,wifi 同步重启 loader 有缓存用户信息导致。
接听不到复电事件,可尝试用 4g 网络测试。有些公司防火墙,或者电脑共享的 wifi 热点网络有限度或不稳固。
以上教训都是无数次排错总结进去的,看了至多能帮你节俭两个工作日。
